The Diagnostic Accuracy of Serum Alpha-Fetoprotein Levels in Follow-up for Recurrence of Sacrococcygeal Teratoma; a Nationwide Review of SCT Cases in the Netherlands. J Pediatr Surg 2024; 59:1740-1745. [PMID: 38418277 DOI: 10.1016/j.jpedsurg.2024.01.048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Revised: 01/20/2024] [Accepted: 01/31/2024] [Indexed: 03/01/2024]
Abstract
BACKGROUND Serum alpha-fetoprotein (AFP) is often used as tumour marker for recurrent sacrococcygeal teratoma (SCT). We aimed to assess the normal dynamics of serum AFP levels after initial resection and diagnostic accuracy of serum AFP levels the follow-up for recurrence in SCT. METHODS This retrospective study included 57 patients treated for SCT in the six pediatric surgical centers in the Netherlands from 1980 to 2018. MAIN RESULTS 57 patients were included in the study of whom 19 children developed 20 recurrences at a median of 14.0 months after initial resection. No significant difference was found in serum AFP level dynamics between the recurrence and non-recurrence group after initial resection (p = 0.950). Serum AFP levels did not significantly increase before recurrence (p = 0.106) compared to serum AFP levels of children without recurrence at the same time. However, serum AFP levels did significantly increase in malignant recurrences (n = 7) (p = 0.03) compared to patients without recurrence. A cut-off value of 55 μg/L was found to be predictive for recurrent SCT with an Area Under the Curve (AUC) of 0.636 with sensitivity of 50% and specificity of 100%. CONCLUSION Dynamics of serum AFP levels are not different between patients with and without recurrence after initial resection of SCT. Serum AFP levels are not predictive for mature or immature recurrent SCT and normal AFP levels do not rule out recurrent SCT. However, serum AFP levels exceeding 55 μg/L can indicate recurrent SCT, especially malignant recurrences.

Abstract
Ovarian germ cell tumors constitute a rare and intricate spectrum of neoplasms characterized by diverse histological subtypes. This comprehensive review elucidates the classification, diagnosis, treatment, prognosis, and unique challenges associated with these tumors. The classification is rooted in histological attributes, with principal subtypes encompassing dysgerminoma, immature teratoma, yolk sac tumor (endodermal sinus tumor), choriocarcinoma, and mixed germ cell tumors. Each subtype bears distinct characteristics and clinical implications, necessitating precise diagnosis and tailored therapeutic strategies. Diagnosis hinges upon recognizing the broad clinical presentation, employing imaging techniques (such as ultrasound and MRI), evaluating tumor markers (alpha-fetoprotein and beta-human chorionic gonadotropin), and conducting histopathological examinations where necessary. Staging, primarily utilizing the International Federation of Gynecology and Obstetrics (FIGO) system, is pivotal in determining the extent of disease, guiding treatment choices, and facilitating prognostic assessment. Treatment modalities encompass surgery, chemotherapy (including standard regimens and emerging therapies), radiation therapy, targeted therapies, and immunotherapy. Prognosis is influenced by histological subtype, tumor stage, patient age, surgical success, response to chemotherapy, and tumor markers, while predictive biomarkers are continually emerging. Despite advances in treatment, ovarian germ cell tumors pose distinct challenges, including late diagnosis, treatment-related side effects, and the enigma of chemoresistance. An integral aspect of comprehensive care is supportive strategies to manage symptoms and offer psychological and emotional support. This review accentuates the vital role of early diagnosis and multidisciplinary care in optimizing outcomes. Future research directions and evolving clinical practices are explored in these intricate and distinctive malignancies, highlighting the dynamic landscape of ovarian germ cell tumors.

Abstract
OBJECTIVE Our meta-analysis was performed to explore the prognostic factors for overall survival among post-hepatectomy patients with spontaneous ruptured hepatocellular carcinoma (SRHCC). METHODS PubMed, EMBASE, the Cochrane Library, and Web of Science were all searched up for relevant studies regarding prognostic factors with SRHCC. RevMan5.3 software and Stata 14.0 software were used for statistical analysis. RESULTS A total of nineteen studies with 1876 resected SRHCC patients were finally identified. Pooled results indicated that preoperative AFP (high vs low) (P = 0.003), concurrent liver cirrhosis (yes vs no) (P = 0.02), preoperative liver function (child A vs non-child A) (P = 0.0007), tumor size (large vs small) (P < 0.00001), tumor number (solitary vs multiple) (P = 0.002), satellite foci (yes vs no) (P = 0.0006), micro-vascular invasion (yes vs no) (P < 0.00001), type of hepatectomy (major or minor) (P = 0.04), surgical margin (R + vs R -) (P < 0.00001), and type of hepatectomy (emergency hepatectomy vs staged hepatectomy) (P = 0.005) were prognostic factors for overall survival among post-hepatectomy SRHCC patients. CONCLUSION Apart from some conventional prognostic factors identified in resected patients with SRHCC, numerous prognostic factors have also been unmasked, which might provide clinical reference to stratify patients with different therapeutic regimes.

Abstract
Introduction Teratomas, tumors derived from all 3 fetal germ cell layers, are rarely located in the head and neck region and extremely rare in the Eustachian tube area. Case report The authors present the case of a 2 years old child with chronic ear discharge. Referral diagnosis was tumor or cyst of the temporal bone. Intraoperatively, a solid, hairy tumor located inside the Eustachain tube, with extension into the middle ear space was discovered and removed. Histology revealed a mature teratoma. Review of the literature showed reports of rare similar cases of Eustachian tube teratomas, differentiating themfrom hairy polyps of the rhynopharynx. The imaging of our patient, the surgical techique for removal of the tumor and long term follow-up are detailed. Conclusions Teratomas located inside the Eustachian tube are exceptional. Their removal should be carefully planned in view of their long term anatomical sequelae and in order to avoid long term postoperative morbidity.

Abstract
Progressive liver fibrosis is the most common phenotype in biliary atresia (BA). A number of pathways contribute to the fibrosis process so comprehensive understanding the mechanisms of liver fibrosis in BA will pave the way to improve patient's outcome after operation. In this study, the differentially expressed profiles of mRNAs and long non-coding RNAs from BA and choledochal cyst (CC) liver tissues were investigated and analyzed, which may provide potential clues to clarify hepatofibrosis mechanism in BA. A total of two BA and two CC liver tissue specimens were collected, the expression level of mRNAs and lncRNAs was detected by RNA sequencing. Differentially expressed mRNAs (DEmRNAs) were functionally annotated and protein-protein interaction networks (PPI) was established to predict the biological roles and interactive relationships. Differentially expressed lncRNAs (DElncRNAs) nearby targeted DEmRNA network and DElncRNA-DEmRNA co-expression network were constructed to further explore the roles of DElncRNAs in BA pathogenesis. The expression profiles of significant DEmRNAs were validated in Gene Expression Omnibus database. A total of 2,086 DEmRNAs and 184 DElncRNAs between BA and CC liver tissues were obtained. DEmRNAs were enriched in 521 Gene Ontology terms and 71 Kyoto Encyclopedia of Genes and Genomes terms which were mainly biological processes and metabolic pathways related to immune response and inflammatory response. A total of five hub proteins (TYRO protein tyrosine kinase binding protein, C-X-C motif chemokine ligand 8, pleckstrin, Toll-like receptor 8 and C-C motif chemokine receptor 5) were found in the PPI networks. A total of 31 DElncRNA-nearby-targeted DEmRNA pairs and 2,337 DElncRNA-DEmRNA co-expression pairs were obtained. The expression of DEmRNAs obtained from RNA sequencing were verified in GSE46960 dataset, generally. The present study identified key genes and lncRNAs participated in BA associated liver fibrosis, which may present a new avenue for understanding the patho-mechanism for hepatic fibrosis in BA.

Abstract
Vascular anomalies represent a diverse group of complex disorders that can cause significant complications, including coagulopathies, pain, and decreased function. The diagnosis of vascular anomalies is often challenging due to heterogeneity of presenting phenotypes and overlapping clinical features with other pediatric conditions. Pediatric hematologists/oncologists (PHO) are uniquely positioned for an essential role in diagnosing, managing, and coordinating the multidisciplinary care required to maximize the quality of life of these patients. Here, we review the diagnostic approach involved in patients with vascular anomalies and utilize cases to highlight the challenges involved, and how PHOs can play a vital part in the care of these patients.

Abstract
Pre- and post-pubertal testicular tumors are two distinct entities in terms of epidemiology, diagnosis and treatment. Most pre-pubertal tumors are benign; the most frequent are teratomas, and the most common malignant tumors are yolk-sac tumors. Post-pubertal tumors are similar to those found in adults and are more likely to be malignant. Imaging plays a pivotal role in the diagnosis, staging and follow-up. The appearance on ultrasonography (US) is especially helpful to differentiate benign lesions that could be candidates for testis-sparing surgery from malignant ones that require radical orchidectomy. Some specific imaging patterns are described for benign lesions: epidermoid cysts, mature cystic teratomas and Leydig-cell tumors. Benign tumors tend to be well-circumscribed, with decreased Doppler flow on US, but malignancy should be suspected when US shows an inhomogeneous, not-well-described lesion with internal blood flow. Imaging features should always be interpreted in combination with clinical and biological data including serum levels of tumor markers and even intra-operative frozen sections in case of conservative surgery to raise any concerns of malignity. This review provides an overview of imaging features of the most frequent testicular and para-testicular tumor types in children and the value of imaging in disease staging and monitoring children with testicular tumors or risk factors for testicular tumors.

Abstract
Infantile hepatic hemangioendothelioma/hemangioma is the most common benign hepatic vascular tumor of infancy, comprising approximately 1% of all childhood tumors. The tumor can present during the fetal or neonatal period as a hepatic mass. Common presentations include abdominal distension and a palpable hepatic mass. Clinico-radio-pathological correlation is essential for a definite diagnosis. Frequent complications such as congestive heart failure, thrombocytopenia, anemia, and Kasabach-Merritt syndrome should be investigated. Chemotherapy has been reported as an effective treatment option. Surgical resection has an essential role for symptomatic patients with medical treatment failure or other certain conditions such as refusal to take medication. Furthermore, prenatal diagnosis is essential for better patient outcomes due to prompt treatment in the neonatal period. We report a case of a female infant at 39 weeks of gestation who was delivered from a 32-year-old mother. The infant was in utero diagnosed by ultrasonography with a hepatic mass, most likely hemangioma. The mass was resected after birth and it was diagnosed as infantile hepatic hemangioendothelioma type II. The course of the disease was excellent and the patient was cured after treatment.

Abstract
OBJECTIVE To determine the overall survival (OS) and prognostic factors influencing outcomes in children and adolescents with malignant extracranial germ cell tumours (MEGCTs) in preparation for the development of a harmonised national treatment protocol. METHODS A retrospective folder review was undertaken at nine South African paediatric oncology units to document patient profiles, tumour and treatment-related data and outcomes for all children with biopsy-proven MEGCTs from birth up to and including 16 years of age. RESULTS Between 1 January 2000 and 31 December 2015, 218 patients were diagnosed with MEGCTs. Female sex (hazard ratio [HR] 0.284, p = .037) and higher socio-economic status (SES) (HR 0.071, p = .039) were associated with a significantly lower risk of death. Advanced clinical stage at diagnosis significantly affected 5-year OS: stage I: 96%; stage II: 94.3%; stage III: 75.5% (p = .017) and stage IV (60.1%; p < .001). There was a significant association between earlier stage at presentation and higher SES (p = .03). Patients with a serum alpha-fetoprotein (AFP) level of more than 33,000 ng/ml at diagnosis had significantly poorer outcomes (p = .002). The use of chemotherapy significantly improved survival, irrespective of the regimen used (p < .001). CONCLUSIONS The cohort demonstrated a 5-year OS of 80.3% with an event-free survival (EFS) of 75.3%. Stage, the use of chemotherapy and an elevated serum AFP level of more than 33,000 ng/ml were independently predictive of outcome. The relationship between SES and outcome is important as the implementation of the new national protocol hopes to standardise care across the socio-economic divide.

Abstract
Germ cell tumors (GCTs) are a heterogenous group of neoplasms in children and young adults, in which serum tumor markers have been demonstrated to be highly sensitive diagnostic and monitoring tools. The known "old" serum biomarkers, alpha-fetoprotein (AFP), human choriogonadotropin (β-hCG) and lactate dehydrogenase (LDH), have some limitations in sensitivity and specificity. MIRNAs from the miR-371~373 (chromosomal locus 19q13.41) and miR-302/367 (4q25) clusters are universally over-expressed in malignant GCT tissue samples. The levels of miRNAs from these clusters are elevated in the serum. They seem to be highly sensitive and specific in malignant GCTs diagnosis and disease assessment during treatment and follow-up. The aim of our review was to present the role of serum tumor markers in the clinical staging, treatment monitoring and follow-up of pediatric patients with GCTs and show new possibilities. The serum levels of miRNAs seem to be a new, promising essential tool in the clinical management of GCTs.

Abstract
Alpha-fetoprotein (AFP) is an oncofetal glycoprotein that has been used as a tumor marker for hepatocellular carcinoma (HCC) in combination with ultrasound and other imaging modalities. Its utility is limited because of both low sensitivity and specificity, and discrepancies among the different methods of measurements. Moreover, its accuracy varies according to patient characteristics and the AFP cut-off values used. Combination of AFP with novel biomarkers such as AFP-L3, Golgi specific membrane protein (GP73) and des-gamma-carboxyprothrombin significantly improved its accuracy in detecting HCC. Increased AFP level could also signify severity of hepatic destruction and subsequent regeneration and is commonly observed in patients with acute and chronic liver conditions and cirrhosis. Hereditary and other non-hepatic disorders can also cause AFP elevation.

Cattoni A, Albanese A. Case report: Fluctuating tumor markers in a boy with gonadotropin-releasing hormone-independent precocious puberty induced by a pineal germ cell tumor. Front Pediatr 2022; 10:940656. [PMID: 36081625 PMCID: PMC9445167 DOI: 10.3389/fped.2022.940656] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Accepted: 08/04/2022] [Indexed: 11/25/2022] Open
Abstract
GnRH-independent precocious puberty (GIPP) can be the presenting clinical picture experienced by patients with secreting germ cell tumor (GCT). Indeed, as luteinizing hormone (LH) and human chorionic gonadotropin (hCG) share identical α-subunits and similar β-subunits, an increased secretion of β-hCG may result in a precocious activation of Leydig cells. Though the co-occurrence of raised β-hCG levels and signs of precocious virilization usually prompts a complete oncological work-up, the diagnostic and therapeutic management of GCT-induced GIPP may be challenging. We report the case of a 6.2 year-old boy presenting with clinical and biochemical findings consistent with GIPP (discrepancy between overt virilization and pre-pubertal testicular volume, suppressed gonadotropins and remarkably raised testosterone). Brain imaging detected a bilobed cyst of the pineal gland, while serum and cerebrospinal baseline assessment initially ruled out raised alpha-fetoprotein or β-hCG levels. Nevertheless, a strict biochemical follow-up highlighted a fluctuant trend of tumor markers, with a more aggressive behavior and recurrent erections occurring as a result of unpredictable phases of raised testosterone and serum/cerebrospinal β-hCG, followed by sudden spontaneous decrease. Accordingly, a secreting pineal GCT was suspected. Given the fluctuating trend of tumor markers, surgery was initially kept on hold and a combined treatment with bicalutamide (androgen receptor blocker) and anastrozole (aromatase inhibitor) was undertaken in order to prevent the patient from experiencing further virilization and excessive bone age maturation. Subsequently, a progression in the size of the pineal tumor prompted surgical resection and a diagnosis of secreting GCT was histologically confirmed. Accordingly, the patient was started on adjuvant chemo- and radiotherapy. Antineoplastic treatment was followed by persistent and remarkable decrease of tumor markers and by a complete pubertal arrest. We reported the challenging diagnosis of a secreting pineal GCT in a patient with GIPP and a fluctuating trend of tumor markers, testosterone levels and associated clinical signs, hence prompting the indication for a systematic assessment and a strict monitoring whenever a patient with GnRH-independent precocious puberty shows clinical or radiological markers potentially consistent with a GCT.

Abstract
BACKGROUND Testicular tumors in prepubertal boys account for 1-2% of all solid pediatric tumors. They have a lower incidence, a different histologic distribution and are more often benign compared to testicular tumors in the adolescent and adult group. This fundamental difference should also lead to a different approach and treatment. OBJECTIVE To provide a guideline for diagnosis and treatment options in prepubertal boys with a testicular mass. METHOD A structured literature search and review for testicular tumors in prepubertal boys was performed. All English abstracts up to the end of 2019 were screened, and relevant papers were obtained to create the guideline. RESULTS A painless scrotal mass is the most common clinical presentation. For evaluation, high resolution ultrasound has a detection rate of almost 100%, alpha-fetoprotein is a tumor marker, however, is age dependent. Human chorionic gonadotropin (HCG) was not a tumor marker for testis tumors in prepubertal boys. CONCLUSION Based on a summary of the literature on prepubertal testis tumors, the 2021 EAU guidelines on Pediatric Urology recommend a partial orchiectomy as the primary approach in tumors with a favorable preoperative ultrasound diagnosis.

Abstract
RATIONALE Teratomas are solid tumors that may occur in both gonadal and extragonadal locations, depending on the age of the child. Benign cystic teratomas are relatively common tumors among women of reproductive age, but they can occur at any age. The clinical presentation is not specific. They can be found incidentally when patients are investigated for other conditions or they can present as emergencies when the ovarian teratoma is torsioned or ruptured. PATIENT CONCERNS We present the case of a 17-year-old adolescent girl that was seen in our emergency department on several occasions for recurrent episodes of abdominal pain ongoing for 6 months. DIAGNOSIS An ultrasonography (US) was performed as an outpatient and a left ovarian mass was found along with right ureterohydronephrosis (UHN). Further assessment of the mass was done by abdominal and pelvic CT and tumoral markers. CT appearance was more suggestive of a teratoma. INTERVENTIONS She underwent laparotomy with complete excision of the tumor. OUTCOME The patient had an uneventful recovery. A renal US follow up showed reduction of the dilatation, demonstrating that the condition was secondary to tumor compression. LESSONS In a teenager with nonspecific symptoms, a high suspicion index for tumors is mandatory. An early diagnosis and management avoid complications like UHN.

Abstract
Owing to advances in treatment paradigms across the last five decades, testicular cancer is now eminently curable. However, current serum tumour and imaging biomarkers lack adequate sensitivity, specificity, and predictive value. Subsequently, their utility in detecting active malignancy and informing treatment decisions is minimal in a large proportion of men with testicular cancer. Micro-ribonucleic acids (miRNA), pertinently miR-371a-3p, offer a new tool, which based on early data, appears to fill many of the gaps that existing biomarkers leave. This paper reviews the evolution of the technology, potential limitations, and discusses the clinical relevance of miRNA as it moves towards the clinic.

Abstract
Pancreatoblastoma (PBL) is a rare malignant epithelial neoplasm that affects typically young children. Signs related to advanced upper-abdominal tumor accompanied by elevated serum α-fetoprotein levels in a young child suggest PBL, however histopathological confirmation is mandatory. The mainstay of the treatment is a complete surgical resection. Unresectable and/or metastatic PBL may become amenable to complete delayed surgery after neoadjuvant chemotherapy. This manuscript presents the international consensus recommendations for the diagnosis and treatment of children with PBL, established by the European Cooperative Study Group for Pediatric Rare Tumors (EXPeRT) within the EU-funded PARTNER (Paediatric Rare Tumors Network - European Registry) project.

Abstract
As part of the European Union-funded project designated Paediatric Rare Tumours Network - European Registry (PARTNER), the European Cooperative Study Group for Pediatric Rare Tumors (EXPeRT) is continuously developing consensus recommendations in order to harmonize standard care for very rare solid tumors of children and adolescents. This paper presents the internationally recognized recommendations for the diagnosis and treatment of sex cord stromal tumors (SCST). The clinical approach to sex cord stromal tumors of the testis (TSCST) and ovary (OSCST) depends on histological differentiation and tumor stage. Virtually all TSCSTs present as localized nonmetastatic tumors, with excellent prognosis after complete resection. In contrast, the prognosis of OSCSTs may be adversely affected by tumor spillage during surgery or presence of metastases. In these cases, cisplatin-based chemotherapy is recommended. Of note, some SCSTs may develop in the context of tumor predisposition syndromes, for example, DICER-1, so that specific follow-up is indicated. SCSTs should be diagnosed and treated according to standardized recommendations that include reference pathology, genetic testing for tumor predisposition syndromes in selected cases, and stratified adjuvant chemotherapy in patients with unfavorable risk profile. To ensure high quality of diagnosis and therapy, patients should be enrolled into prospective registries.

Abstract
BACKGROUND The incidence of children developing recurrent sacrococcygeal teratoma (SCT) is 2-35%. Serum alpha-fetoprotein (AFP) is often used as a tumor marker for (malignant) recurrences of SCT and could potentially be used during routine follow-up after SCT resection. However, the diagnostic accuracy of serum AFP levels during follow-up has not been well established. Therefore, we aimed to systematically review the diagnostic accuracy of serum AFP levels in recurrent SCT. METHODS We queried Search Premier, COCHRANE Library, EMCARE, EMBASE, PubMed, ScienceDirect and Web of Science databases to identify studies regarding patients with SCT with follow-up using serum AFP levels postoperative. We estimated sensitivity and specificity of serum AFP levels. RESULTS Fifteen studies (613 patients, 121 recurrences) were included and these mainly described serum AFP levels in patients with recurrent SCT (n = 111); 83 (75%) patients with recurrent SCT had elevated serum AFP levels. A subgroup analysis of articles that measured serum AFP levels in all patients (n = 6, 136 patients, 14 recurrences) showed a sensitivity and specificity of 79% and 95%, respectively. The sensitivity of AFP levels to detect malignant recurrence was 96%. CONCLUSION Diagnostic accuracy of serum AFP levels to detect recurrent SCT seems promising, though sensitivity could be overestimated since serum AFP levels are mainly described in patients with elevated AFP levels or at recurrent SCT. Furthermore, serum AFP levels could be helpful to detect malignant recurrences. TYPE OF STUDY Systematic review of level 2-4 studies. LEVEL OF EVIDENCE Level 2-4 (mostly level 2).

Abstract
BACKGROUND Pancreatoblastoma is an extremely rare neoplasm that accounts for 0.5% of all pancreatic exocrine tumors. These rare entities typically manifest in the pediatric population but can rarely occur in adults. Systemic seeding has been described before but intracranial metastasis in adults has yet to be described. CASE DESCRIPTION A 28-year-old woman with a history of pancreatoblastoma that had been in remission for 51 months after treatment with cisplatin, doxorubicin (Adriamycin), and etoposide had presented to the emergency room with chronic recurrent headaches. Conservative management of the headaches failed, which led to a diagnostic workup with magnetic resonance imaging of the brain. Magnetic resonance imaging demonstrated a well-circumscribed solitary cerebellar lesion. Metastatic disease was suspected, and the patient underwent suboccipital craniotomy for tumor resection with adjuvant gamma knife radiosurgery. CONCLUSIONS Central nervous system seeding of pancreatoblastoma is rare, and the available evidence suggests that the strategy we used could be adequate for treating such occurrences.

Abstract
AbstractChoriocarcinoma can occur at ectopic extragenital locations such as lungs, mediastinum, retroperitoneum, and even in the brain (nongestational choriocarcinoma). Choriocarcinoma arising in the urinary bladder is extremely uncommon with only a few cases reported worldwide. It is important to recognize and give comprehensive diagnosis of this entity, as it has poorer prognosis as compared to the conventional gestational choriocarcinoma and requires stepped-up chemotherapy. Here, we present such a case in a 19-year-old girl and the diagnostic conundrum associated with it.

Abstract
In prepubertal boys, testicular tumors are rare with an incidence between 2 and 5/million. In contrast to testicular tumors in adolescents and adults, more than 2/3 of these tumors are benign. Unfortunately, in Germany in most cases, only malignant tumors (usually yolk sac tumors) are reported to the study center (MAKEI IV and now V). Therefore, the incidence in Germany is unknown. Since the introduction of polychemotherapy in the 1970s, the prognosis of malignant testicular tumors has improved enormously and has become a curable disease, even in the case of recurrence. Today the orchiectomy, which was usually carried out in the past, appears to be no longer justified in most prepubertal boys due to the high incidence of benign tumors. It has been shown in various studies that organ-sparing surgery in germ cell tumors (epidermoid cysts, teratoma); gonadal stoma tumors (Sertoli, Leydig and granulosa cell tumors) and cystic lesions (intratesticular cysts and tubular ectasia of the rete testis) is reliable and safe. In cases with preoperative significantly increased AFP (caution: norm values not valid in the first year of life) and a clear testicular tumor in the ultrasound (yolk sac tumor) or if no testicular parenchyma is sonographically detectable, orchiectomy can still be carried out. Today orchiectomies in prepubertal boys should be an exception and the reasons for an orchiectomy must be well documented.

Abstract
Infantile hepatic hemangioma, the most common vascular tumor of the liver in infancy, can occur with acute postnatal liver and congestive heart failure. Nevertheless, its course is often benign, and many children can be diagnosed and treated without surgical intervention. The distinction from malignant diseases is not always easy and it not clear whether invasive procedures for diagnosis and therapy should be performed. Here we report our experiences in our Center for Pediatric Liver Disease and postulate that large studies are needed to avoid unnecessary invasive procedures for these patients in the future.

Abstract
Hepatoblastoma (HB) is the most common malignant liver tumor in children. The level of alpha-fetoprotein (AFP) is used for monitoring the response to antitumor therapy and for diagnosing relapses. The occurrence of HB relapses with normal AFP levels in patients who had elevated levels of this tumor marker at disease onset is considered to be an uncommon situation. The aim of this study was to describe cases in which AFP-negative hepatoblastoma relapses developed. The study participants included two HB patients who were initially stratified into high-risk and standard-risk groups and who received treatment at the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology and the Petrovsky National Research Center of Surgery inMoscow. At the moment of relapse acknowledgement these patients had normal AFP levels, which was confirmed by serial measurements. Immunohistochemistry (IHC) tests were performed on paired samples of the tumor at disease onset and at disease relapse respectively to evaluate AFP expression. The presented clinical cases demonstrate that normal AFP levels, when accompanied by suspicious clinical symptoms, do not allow to exclude an HB relapse. The possibility of relapse with a normal AFP level reinforces the importance of following the current plan of screening tests, which includes not only an evaluation of AFP levels, but also other tests such as a chest X-ray and an abdominal ultrasound. Parents gave their consent to use information about the child in the article.

Abstract
OBJECTIVE To establish reference ranges for serum α-fetoprotein (AFP) at various ages in patients with Beckwith-Wiedemann spectrum (BWSp), to better predict the risk for hepatoblastoma in this population. STUDY DESIGN A retrospective analysis of AFP measurements collected from patients with BWSp was performed. Factors including sex, prematurity, molecular diagnosis of patients, and performing laboratory were evaluated for significant differences. In total, 1372 AFP values were collected from 147 patients and the predictive AFP values at various ages were calculated to establish reference ranges. Mixed-effects polynomial regression models were used to study various potential factors affecting log(AFP) values. RESULTS Overall, predicted AFP values declined to normal range for age (<10 ng/mL) by 14 months old. Patient sex and performing laboratory were found not to influence values. A significant difference was demonstrated between premature and nonpremature patients, and separate reference values were established. Significant differences in the predicted AFP value were not broadly apparent between molecular subtypes; however, interpretation was limited due to the small sample size of some of these subtypes. CONCLUSIONS Predictive AFP values were created for premature and nonpremature patients with BWSp to aid with interpretation and monitoring of the risk for hepatoblastoma. Further analysis is needed to determine whether AFP values differ within the less common molecular subtypes of patients with BWSsp.

Longitudinal Monitoring of Alpha-Fetoprotein by Dried Blood Spot for Hepatoblastoma Screening in Beckwith⁻Wiedemann Syndrome. Cancers (Basel) 2019; 11:cancers11010086.

Abstract
BACKGROUND Hepatoblastoma screening in the Beckwith⁻Wiedemann spectrum (BWSp) is currently based on measuring a specific serum marker alpha-fetoprotein (αFP) every three months until the fourth birthday. Frequent blood draws can be a burden for patients and their families. METHODS We have developed a less invasive alternative testing method based on measuring αFPs from dried blood spots (DBS). The method was validated with 259 simultaneous plasma and DBS αFP measurements in 171 children (132 controls and 39 patients with BWSp). RESULTS The DBS and plasma measurements overlapped across the wide range of αFP concentrations independent of patient age (p < 0.0001), demonstrating the utility of this method for longitudinal monitoring. Occasional differences between measurements by the two techniques fell within standard laboratory error and would not alter clinical management. CONCLUSIONS This novel method shows consistent overlap with the traditional blood draws, thereby demonstrating its utility for hepatoblastoma screening in this setting and alleviating the burden of frequent blood draws. This also may help increase patient compliance and reduce costs of health care screening. The DBS-based method for the measurement of cancer biomarkers may also be applied to several other chronic diseases with increased risks of αFP-producing liver tumors.

Abstract
BACKGROUND Alpha-fetoprotein (AFP) is useful as a tumor marker for sacrococcygeal teratoma (SCT). We investigated the half-life of AFP in SCT. METHODS Neonates who underwent surgical treatment for SCT between 1997 and 2016 were included in the study, whereas patients who died before or after surgery or had malignant germ cell tumors were excluded. RESULTS Fifty-five non-recurrent SCT patients (M:F = 18:37) were enrolled. They underwent surgery on average 7.4 ± 4.1 days after birth. Serum AFP was measured an average 4.25 ± 2.07 times per patient. We obtained 165 half-lives following the formula (M = Mo * (1/2) Δt/T). A positive correlation was observed between half-life and patient age using the formula T1/2 = 0.0597 × days +6.1643 (p < 0.001). It was different from recurrent SCT (T1/2 = 0.1196 × days -0.0633) (p < 0.05). Half-life was different between mature SCT (T1/2 = 0.0671 × days +4.3912) and immature SCT (T1/2 = 0.0433 × days +8.9339) (p < 0.05). CONCLUSION The half-life of AFP in neonatal patients with SCT was prolonged in proportion to the age, and it was getting longer in recurrent tumor than non-recurrent tumor. The half-life of AFP was longer in immature teratoma than in mature teratoma. LEVEL OF EVIDENCE IV.

Abstract
Abstract
Background
Measurement of α-fetoprotein (AFP) concentrations in the serum of infants is useful for the management of testicular germ cell tumors, hepatoblastoma and hepatocellular carcinoma. Here, we provide a critical review of the available information about pediatric reference intervals (RI), focusing on their utility in interpreting AFP as an aid for cancer diagnosis.
Content
Evidence sources in the available literature were critically appraised. Out of 3873 retrieved papers, 24 were finally selected and carefully inspected, and six of them overcame exclusion criteria (i.e. methodological limitations in the study design, statistical gaps, drawbacks in traceability of the AFP assay to higher order materials and/or biased reporting of AFP results). Preterm and term infants up to the 3rd month of life exhibited the highest average AFP concentrations, but the attempt of defining RI by data pooling and partitioning for age intervals was impeded by the wide variability of data. The inability of defining robust RI in the first months of life made difficult, if not impossible, using upper reference limits for ruling out malignancies with a single AFP result. Evaluating the behavior of AFP concentrations 5 days from the baseline result, if this exceeds risk thresholds partitioned for age, according to the formula Xt=X0*2−t/HL (where: t=days elapsed for AFP retest; HL=AFP half-life according to age; X0=AFP baseline concentration, and Xt=predicted AFP concentration at day 5), could give a better information.
Summary
Novel studies defining AFP RI in infants based on robust methodology are warranted to improve the interpretation of AFP results in pediatric oncology. In the meantime, algorithms based on both serum AFP absolute concentrations and HL may aid in cancer diagnosis.

Abstract
INTRODUCTION Testicular tumors in children have two peaks with different types of tumors; in the first 4 years of life a third to half are benign with increased risk of malignancy during puberty. The pathology of testicular tumors between these peaks, at the age of 5-12 years, is not known. We hypothesized that because of the low level of testosterone at this time, the incidence of malignant tumors is very low. OBJECTIVE To compare malignancy risk of primary testicular tumors in children in the prepubertal period (5-12 years) compared with younger (0-4 years) and pubertal (13-18 years) children. STUDY DESIGN We retrospectively (2002-2016) identified patients <18 years with surgery for primary testicular tumor. Patients with testicular tumor risk were excluded. Ultrasound studies were reviewed for contralateral testis volume, tumor morphology, and tumor maximal diameter, for three age groups: 0-4, 5-12, and 13-18 years. The Freeman-Halton extension of the Fisher exact probability test was adopted for categorical outcomes, and one-way ANOVA for continuous outcomes. RESULTS Fifty-two patients (mean age 11.0 years, range 6 days-18 years) were identified. Malignant tumor prevalence significantly differed (p < 0.01) among age groups (Fig).: 0-4 (72.7%, 8/11), 5-12 (0%, 0/16), and 13-18 years (44.0%, 11/25). The most common tumor types in 5-12 years were epidermoid cyst (31.3%, 5/16) and tumor mimics (37.5%, 6/16). Prevalence of cystic tumors in 5-12 year olds was not significantly different compared with other age groups. Contralateral testicular volume >4 mL (pubertal surge) significantly (p < 0.01) differed among groups: 0-4 years (0/11), 5-12 years (3/16), and 13-18 years (19/20). In children aged 13-18 years the mean tumor maximal diameter (29.8 ± 4.4 mm) was significantly larger (p < 0.01) compared with children 5-12 years (9.3 ± 5.5 mm) and all malignant tumors had contralateral testicular volume >4 mL. DISCUSSION We found that preadolescent children between the ages of 5 and 12 years have distinctive characteristics compared with the other age groups. Most importantly, no malignant testicular tumors were found in this age group. About a third of the children presented with an incidental testicular mass. The testicular tumors were significantly smaller (9.3 ± 6.7 mm) compared with those in children aged 13-18 years (29.8 ± 4.4 mm). There were limitations because of the retrospective nature of the study. CONCLUSION We found no malignant testicular tumors in children aged 5-12 years with no risk factors and prior to pubertal surge. Our study suggests use of more conservative treatment in this group of patients.

Abstract
Germ cell (yolk sac) tumors are rare tumors that often have a poor prognosis because they are not usually found until metastases have occurred. The diagnosis of yolk sac tumors is usually a multimodality diagnosis in conjunction with a biopsy of the lesion. This case study outlines the initial stages of diagnosing and treating a 22-month-old male patient who was found to have a widespread malignant yolk sac tumor in his abdominopelvic cavity. Sonography was used as the primary imaging modality due to the patient’s age, but it was soon determined that a follow-up with computed tomography was necessary. Because of the complicated nature and progression of the tumor, a surgical biopsy was then performed. During the procedure, it was also noted that the mass was hypervascular with extensive blood flow throughout the mass. Excision was not an option and chemotherapy treatment was recommended.

Abstract
PURPOSE This study retrospectively investigated the cases of testicular tumors/masses treated in our center from 2002 to 2017 and analyzed their epidemiologic features. METHODS Data were collected by searching our center's database using "testicular tumor" or "testicular mass" as keywords. Patients not operated in our hospital were excluded. Preoperative serum alpha-fetoprotein (AFP) levels were reviewed in germ cell tumor (GCT) cases and analyzed to predict malignancy in various age groups. RESULTS In total, 230 cases were identified: 151 were benign (78 in the left, 72 in the right, and 1 bilateral) with 3.63years mean age during the operation, and 79 were malignant (42 in the left, 36 in the right, and 1 bilateral) with 2.21years mean age during the operation. Main pathological diagnoses were mature teratoma (92, 40.00%), yolk sac tumor (53, 23.04%), dermoid cyst (23, 10.00%), embryonic carcinoma (15, 6.53%), immature teratoma (14, 6.09%), benign cyst (8, 3.48%), Leydig cell tumor (6, 2.61%), and paratesticular rhabdomyosarcoma (5, 2.17%). All GCT cases with AFP >1000ng/ml, >100ng/ml, >20ng/ml were malignant in <7-, 7-9-, and ≥10-month-old groups, respectively. CONCLUSIONS Radical inguinal orchiectomy without biopsy is suggested in 7-9- and ≥10-month-old cases with AFP >100ng/ml and >20ng/ml, respectively. TYPE OF STUDY Retrospective Study. LEVEL OF EVIDENCE Level III-IV.

Abstract
INTRODUCTION Ataxia-telangiectasia (A-T) a multisystem disorder primarily characterized by cerebellar degeneration, telangiectasia, immunodeficiency, cancer susceptibility and radiation sensitivity. Identification of the gene defective in this syndrome, ataxia-telangiectasia mutated gene (ATM), and further characterization of the disorder together with a greater insight into the function of the ATM protein have expanded our knowledge about the molecular pathogenesis of this disease. Area covered: In this review, we have attempted to summarize the different roles of ATM signaling that have provided new insights into the diverse clinical phenotypes exhibited by A-T patients. Expert commentary: ATM, in addition to DNA repair response, is involved in many cytoplasmic roles that explain diverse phenotypes of A-T patients. It seems accumulation of DNA damage, persistent DNA damage response signaling, and chronic oxidative stress are the main players in the pathogenesis of this disease.

Abstract
Background Pediatric germ cell tumors account for approximately 3.5 % of all childhood cancers for children under the age of 15 years. Up to one-third are extragonadal neoplasms. Germ cell tumors are a heterogeneous group of malignant tumors with a wide variety of histopathological features. Yolk sac tumor is the predominant variant in newborns and younger children. We report for the first time, the presentation of a primary yolk sac tumor in the abdominal wall of a small child. Case presentation An 18-month-old white girl underwent resection of a small, round subcutaneous lump (1.5×1.3×0.8 cm) of the abdominal wall in her right hypochondriac region. The histopathology was compatible with yolk sac tumor. Her alpha-fetoprotein was initially elevated but normalized after the resection. Magnetic resonance imaging of her abdomen was normal. The surgeon decided to observe and follow her alpha-fetoprotein level closely. One year after resection a local recurrence appeared and her alpha-fetoprotein rose to 58 ng/mL. The surgeon performed a wide resection of the lesion with normalization of her alpha-fetoprotein. Follow-up consisted of measuring alpha-fetoprotein, clinical evaluation, and abdominal ultrasound. Conclusions Clinicians should be aware that a yolk sac tumor can present in an unusual extragonadal place, for example in this case it was subcutaneous. In some cases, conservative treatment can be carried out with careful monitoring of the patient and their alpha-fetoprotein.

Abstract
Testicular germ cell tumours (GCTs) are the most common malignancy occurring in young adult men and the incidence of these tumours is increasing. Current research priorities in this field include improving overall survival for patients classified as being 'poor-risk' and reducing late effects of treatment for patients classified as 'good-risk'. Testicular GCTs are broadly classified into seminomas and nonseminomatous GCTs (NSGCTs). The conventional serum protein tumour markers α-fetoprotein (AFP), human chorionic gonadotrophin (hCG) and lactate dehydrogenase (LDH) show some utility in the management of testicular malignant GCT. However, AFP and hCG display limited sensitivity and specificity, being indicative of yolk sac tumour (AFP) and choriocarcinoma or syncytiotrophoblast (hCG) subtypes. Furthermore, LDH is a very nonspecific biomarker. Consequently, seminomas and NSGCTs comprising a pure embryonal carcinoma subtype are generally negative for these conventional markers. As a result, novel universal biomarkers for testicular malignant GCTs are required. MicroRNAs are short, non-protein-coding RNAs that show much general promise as biomarkers. MicroRNAs from two 'clusters', miR-371-373 and miR-302-367, are overexpressed in all malignant GCTs, regardless of age (adult or paediatric), site (gonadal or extragonadal) and subtype (seminomas, yolk sac tumours or embryonal carcinomas). A panel of four circulating microRNAs from these two clusters (miR-371a-3p, miR-372-3p, miR-373-3p and miR-367-3p) is highly sensitive and specific for the diagnosis of malignant GCT, including seminoma and embryonal carcinoma. In the future, circulating microRNAs might be useful in diagnosis, disease monitoring and prognostication of malignant testicular GCTs, which might also reduce reliance on serial CT scanning. For translation into clinical practice, important practical considerations now need addressing.

Abstract
OBJECTIVES Surveillance of hepatic nodules for malignant transformation to hepatocellular carcinoma is important in the monitoring of patients with biliary atresia (BA). To date, only 2 published case reports describe the finding of hepatoblastoma (HB) in this setting. The present study aimed to investigate this association of HB and BA, and to assess the utility of alpha-fetoprotein (aFP) as a marker in the diagnosis. METHODS A retrospective study of all patients who underwent isolated liver transplantation (LTx) for the primary diagnosis of BA at a single center, between January 1999 and June 2014, was conducted. Patient demographics, pre-LTx aFP levels, and histologic examination of native liver explants were reviewed. RESULTS One hundred two (44% men, median age 11 months) patients underwent LTx for BA. Two (2%) explants examinations were confirmatory for concomitant HB; both patients had abnormally elevated aFP. Overall, 56 (55%) patients had available pre-LTx aFP levels. Recipients with persistently abnormal aFP levels (n = 20, 36%) were older at hepatoportoenterostomy (107 vs 68 days, P = 0.02) and younger at LTx surgery (359 vs 1713 days, P < 0.01), compared to patients with constantly normal levels (n = 24, 43%). CONCLUSIONS In our cohort, HB was found to coexist in approximately 2% of patients with BA undergoing LTx, far exceeding the hypothetical anticipated incidence of 1:10 billion for the concomitant diagnoses. Elevated serum aFP levels may be sensitive but not specific for HB in this context. Further research is required to identify specific mechanisms and risk factors.

Abstract
Management of paediatric extracranial germ-cell tumours carries a unique set of challenges. Germ-cell tumours are a heterogeneous group of neoplasms that present across a wide age range and vary in site, histology, and clinical behaviour. Patients with germ-cell tumours are managed by a diverse array of specialists. Thus, staging, risk stratification, and treatment approaches for germ-cell tumours have evolved disparately along several trajectories. Paediatric germ-cell tumours differ from the adolescent and adult disease in many ways, leading to complexities in applying age-appropriate, evidence-based care. Suboptimal outcomes remain for several groups of patients, including adolescents, and patients with extragonadal tumours, high tumour markers at diagnosis, or platinum-resistant disease. Survivors have significant long-term toxicities. The challenge moving forward will be to translate new insights from molecular studies and collaborative clinical data into improved patient outcomes. Future trials will be characterised by improved risk-stratification systems, biomarkers for response and toxic effects, rational reduction of therapy for low-risk patients and novel approaches for poor-risk patients, and improved international collaboration across paediatric and adult cooperative research groups.

Abstract
In males, precocious puberty (PP) is defined as the development of secondary sexual characteristics before age 9 years. PP is usually idiopathic; though, organic abnormalities including tumors are more frequently found in male patients with PP. However, advanced puberty in male also can be an important clinical manifestation in tumors. We report 2 cases of rapidly progressive puberty in males, each associated with a germ-cell tumor. First, an 11-year-old boy presented with mild fever and weight loss for 1 month. Physical examination revealed a pubertal stage of G3P3 with 10-mL testes. Investigations revealed advanced bone age (16 years) with elevated basal luteinizing hormone and testosterone levels. An anterior mediastinal tumor was identified by chest radiography and computed tomography, and elevated α-fetoprotein (AFP) and β-human chorionic gonadotropin (β-hCG) levels were noted. Histopathologic analysis confirmed a yolk-sac tumor. Second, a 12-year-old boy presented with diplopia, polydipsia, and polyuria for 4 months. Physical examination revealed a pubertal stage of G3P3 with 8-mL testes. Bone age was advanced (16 years) and laboratory tests indicated panhypopituitarism with elevated testosterone level. A mixed germ-cell tumor was diagnosed with elevated AFP and β-hCG levels. Of course, these patients also have other symptoms of suspecting tumors, however, rapidly progressive puberty can be the more earlier screening sign of tumors. Therefore, in male patients with accelerated or advanced puberty, malignancy should be considered, with evaluation of tumor markers. In addition, advanced puberty in male should be recognized more widely as a unique sign of neoplasm.

Abstract
Aims The embryonic-like stem cell origin of infantile hemangioma (IH) and the observed elevated serum levels of alpha-fetoprotein (AFP) in patients with hepatic IH led us to investigate if this tumor was the source of AFP. Materials and methods We measured serial serum levels of AFP in patients with problematic proliferating IH treated with surgical excision or propranolol treatment. We also investigated the expression of AFP in extrahepatic IH samples using immunohistochemical staining, mass spectrometry, NanoString gene expression analysis, and in situ hybridization. Results Serum levels of AFP normalized following surgical excision or propranolol treatment. Multiple regression analysis for curve fittings revealed a different curve compared to reported normal values in the general populations. AFP was not detected in any of the IH samples examined at either the transcriptional or translational levels. Conclusion This study demonstrates the association of proliferating IH with elevated serum levels of AFP, which normalized following surgical excision or propranolol treatment. We have shown that IH is not the direct source of AFP. An interaction between the primitive mesoderm-derived IH and the endogenous endodermal tissues, such as the liver, via an intermediary, may explain the elevated serum levels of AFP in infants with extrahepatic IH.

Abstract
Protocols for pediatric germ cell tumors (GCT) allow for chemotherapy (CHT) initiation without histological diagnosis, based on typical clinical and radiological picture and increased alphafetoprotein (AFP) or beta-human chorionic gonadotropin serum levels. Such strategy may result in misdiagnoses in rare cases. We present two patients with abdominal tumors and high serum AFP levels, diagnosed as GCT. In both, no tumor shrinkage and increasing AFP was observed after first cycles of multidrug CHT for pediatric GCT. Histological examination of biopsied tumor tissues revealed metastatic cholangiocarcinoma in patient 1 and pancreatoblastoma in patient 2, which implicated immediate change of therapy. Presented cases support the necessity to consider the tumor biopsy when patients diagnosed with GCT based on typical clinical presentation and elevated AFP do not respond to CHT with AFP decrease and tumor size reduction.

Abstract
BACKGROUND Beckwith-Wiedemann syndrome (BWS) and hemihyperplasia (HH) are overgrowth conditions with predisposition to hepatoblastoma for which early diagnosis patients undergo cancer screening based on determination of the tumor marker α-fetoprotein (αFP). Repeated blood draws are a burden for patients with consequent compliance issues and poor adherence to surveillance protocol. We sought to analyze feasibility and reliability of αFP dosage using an analytical micromethod based on blood dried on filter paper (DBS). METHODS Overall 143 coupled αFP determinations on plasma and DBS collected simultaneously were performed, of which 31 were in patients with hepatoblastoma predisposition syndromes and 112 were in controls. The plasma αFP dosage method was adapted to DBS adsorbed on paper matrix for newborn screening. RESULTS There was strong correlation between plasmatic and DBS αFP (r2 = 0.999, P < 0.001). Cohen's k coefficient for correlation was 0.96 for diagnostic cut-off of 10 U/ml (P < 0.001), commonly employed in clinical practice. The measurements on plasma and DBS were highly overlapping and consistent. CONCLUSION The DBS method allowed to dose αFP reliably and consistently for the concentrations commonly employed in clinical settings for the screening of hepatoblastoma, opening new scenarios about conducting cancer screening in overgrowth syndromes.

Abstract
The authors describe a series of 15 intracranial germ cell tumors (IGCTs) excluding mature teratomas; 3 cases in children younger than 3 years of age who were treated at 3 different international institutions over the course of 20 years, and 12 from a PubMed search. These tumors, with possible in utero origins, often occur in atypical locations. The clinical behavior differed significantly from these tumors' counterparts in older children. In this young age group germinoma is highly aggressive, whereas nongerminomatous germ cell tumors may be cured without radiotherapy. Ongoing genomic studies reveal insights to attain an understanding of the biology of these tumors. New treatment strategies are needed to improve outcomes for IGCTs in this age group, particularly for germinomas.

Abstract
The pathologic spectrum of diseases that infiltrate the pituitary infundibulum includes a broad variety of clinical entities. There are significant differences in the prevalence of these etiologies depending on the age of presentation. Lymphocytic infundibuloneurohypophysitis (LINH) predominates over other causes of infundibular disease in adults over age 21. Differentiating LINH from other causes of infundibular disease can be difficult because the various etiologies often have similar clinical presentations and radiologic imaging characteristics. We report the first case in an adult of a mixed germ cell tumor comprised of germinoma and embryonal cell carcinoma infiltrating the pituitary infundibulum. In our case, a 23-year-old female was initially misdiagnosed as having LINH. She presented with panhypopituitarism and diabetes insipidus, which is the most common initial presentation in both entities. The two diagnoses are difficult to distinguish based on MRI imaging, CSF findings, and histopathological examination. Our case demonstrates the need for close follow-up of patients with isolated lesions of the pituitary infundibulum and reinforces the need for biopsy of an infundibular lesion when progression of disease is demonstrated. In our case, biopsy with comprehensive immunohistochemical staining was the sole means of making a definitive diagnosis.
