Clin Case Rep 2024; 12:e8344. [PMID: 38161647 PMCID: PMC10753629 DOI: 10.1002/ccr3.8344] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Revised: 11/21/2023] [Accepted: 11/29/2023] [Indexed: 01/03/2024] Open
Abstract
Primary mediastinum immature teratoma with somatic-type malignant transformation (SM) is extremely rare, and the clinical prognosis is poor. Immature teratoma with SM is difficult to eradicate by chemotherapy due to poor sensitivity; therefore, surgical resection is recommended whenever possible because it may offer better survival.

Abstract
In this case report, we describe a patient who developed metastatic liver cancer of unknown primary origin one year following the surgical removal of a retroperitoneal adenocarcinoma. The retroperitoneal adenocarcinoma is considered a malignant transformation of teratoma (MTT), given the patient's distant history of testicular tumor excised 25 years prior and treated with chemotherapy. Despite no primary tumor being identified, the leading primary hypothesis is that the liver metastasis stemmed from the resected retroperitoneal adenocarcinoma from one year prior. We theorize that the patient's cisplatin-based chemotherapy 25 years ago may have triggered the MTT, as documented in the existing literature. Using TEMPUS gene testing on both the retroperitoneal adenocarcinoma and the recently discovered liver metastasis, we identified several genes with variants of unknown significance (VUS) that could potentially be linked to cisplatin chemotherapy resistance. While we cannot conclude that this patient definitively underwent MTT, it remains the most plausible explanation. Future research should investigate both the validity of the genes we have uncovered with respect to cisplatin resistance, as well as other genes associated with cisplatin resistance to further understand the pathogenesis of cisplatin resistance for better prediction of treatment response. As the world of medicine shifts towards individualized therapies and precision medicine, reporting and analyzing genetic mutations derived from tumors remains imperative. Our case report aims to contribute to the growing database of defined mutations and underscores the immense potential of genetic analysis in directing personalized treatment options.

J Cardiothorac Surg 2022; 17:333. [PMID: 36550490 PMCID: PMC9783718 DOI: 10.1186/s13019-022-02091-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Accepted: 12/11/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Mature teratomas are benign germ cell tumors. On rare occasions, they have been associated with somatic malignancies and are termed rare germ cell tumors with a somatic-type malignancy (GCTSM). Mature teratomas commonly comprise adenocarcinomas; only seven previous cases of mature teratomas with neuroendocrine tumors have been reported to date. Here, we report a patient with a neuroendocrine tumor whithin a mature teratoma. CASE PRESENTATION A 26-year-old man visited our department complaining of chest tightness. Contrast-enhanced computed tomography (CT) scans showed a strongly enhanced lesion within a 10-cm encapsulated cystic lesion in the anterior mediastinum. Positron emission tomography (PET) scans showed no areas of significant 18F-fluorodeoxyglucose (18F-FDG) accumulation. He underwent complete tumor resection via the transsternal approach. Histopathological examination of the specimen indicated a neuroendocrine tumor contained within a mature teratoma. CONCLUSIONS In this case, a neuroendocrine tumor was contained within a mature teratoma. Our patient had no specific symptoms and his serum markers were within the normal range. Although PET is beneficial for diagnosing other GCTSM, it is not useful in detecting a neuroendocrine tumor. Therefore, the preoperative diagnosis of neuroendocrine tumors contained within mature teratomas remains challenging. However, GCTSM should be suspected in patients exhibiting CT findings of a mediastinal tumor, measuring ≥ 6 cm, in addition to characteristic GCTSM findings. Moreover, surgery should be performed carefully in such cases.

The Role of CT in the Staging and Follow-Up of Testicular Tumors: Baseline, Recurrence and Pitfalls. Cancers (Basel) 2022; 14:3965. [PMID: 36010958 PMCID: PMC9406011 DOI: 10.3390/cancers14163965] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 08/08/2022] [Accepted: 08/12/2022] [Indexed: 11/30/2022] Open
Abstract
Ultrasound imaging of the testis represents the standard-of-care initial imaging for the diagnosis of TGCT, whereas computed tomography (CT) plays an integral role in the initial accurate disease staging (organ-confined, regional lymph nodes, or sites of distant metastases), in monitoring the response to therapy in patients who initially present with non-confined disease, in planning surgical approaches for residual masses, in conducting follow-up surveillance and in determining the extent of recurrence in patients who relapse after treatment completion. CT imaging has also an important place in diagnosing complications of treatments. The aims of this article are to review these different roles of CT in primary TGCT and focus on different pitfalls that radiologists need to be aware of.

Abstract
AIMS Somatic malignant transformation (SMT) arising in germ cell tumours (GCTs) is an infrequent, but clinically relevant event. There is only limited knowledge on the morphological spectrum of SMT, and therapeutic management of these patients is poorly defined. In this work we revisit two consecutive case series (n=756) of GCTs. Clinicopathological data of SMT arising in GCT were determined, with focus on the histopathological spectrum, and molecular aspects were obtained by Fluorescence in situ Hybridization (FISH) and Next Generation Sequencing (NGS). METHODS AND RESULTS 30 male patients (28 primary testicular, 2 primary extragonadal) were included. These patients represent 4% of GCT patients diagnosed in two institutes (University Hospital Zurich and IPO Porto). The most common SMT were adenocarcinoma (n=8), embryonic-type neuroectodermal tumours (ENETs, n=8) and rhabdomyosarcoma (n=6), but a wide range of challenging morphologies were depicted, including low-grade neuroglial tumour, adenosquamous carcinoma, neuroblastoma and neuroendocrine carcinoma. SMT was found in 15 primary tumour samples and in 27 metastatic samples of these 30 patients, the latter showing poorer overall-survival. Adenocarcinoma occurred only in metastasis post-chemotherapy and in one primary retroperitoneal GCT with SMT, but not in GCT of the testis. 12p gains were identified by FISH in all cases. NGS results were available in 6 patients. Clinical trials and/or targeted treatments based on the molecular profile of SMT were recommended in 4 patients. CONCLUSIONS SMT arising in GCTs represents a diagnostic challenge and should be confirmed by a specialized uropathologist. NGS based treatment recommendations may improve outcome of these patients.

Abstract
Introduction Germ cell tumor with malignant transformation is extremely rare. We present a case of testicular primitive neuroectodermal tumor with multiple metastases that was effectively managed by surgery, irradiation, and second‐line chemotherapy. Case presentation A 22‐year‐old man was diagnosed as having teratoma including primitive neuroectodermal tumor with lymph node and multiple bone metastases. Five months afterwards the first‐line therapy, his skull metastasis recurred. Vincristine, doxorubicin, and cyclophosphamide therapy followed by vincristine, actinomycin D, and cyclophosphamide therapy was given as second‐line chemotherapy. Computed tomography revealed no disease progression 3 months after the treatments. Conclusion Metastatic primitive neuroectodermal tumor may be successfully managed by multidisciplinary cancer treatment.

Abstract
INTRODUCTION AND IMPORTANCE Teratoma is a rare clinical entity in adults and commonly arises from gonads. Being rare, retroperitoneal teratomas account for 4 % of all primary teratomas. A teratoma can be mature or immature, of which mature is more common in adults and immature is more common in neonates or children. It is labeled immature if at least one from the three germ layers lacks differentiation. To the best of our knowledge, this is the first case of primary retroperitoneal 'immature' teratoma in a male adult. CASE DESCRIPTION A 53-year-old male, following a road traffic accident, was investigated for the same and was incidentally detected with a retroperitoneal mass based on Chest X-ray, USG abdomen, and CT scan reports. CLINICAL FINDINGS AND INVESTIGATIONS A painless palpable mass was identified on examination after the patient was referred to our tertiary care hospital for surgical benefit. AFP, HCG and LDH were tested and reported normal. INTERVENTIONS AND OUTCOMES An exploratory laparotomy was done and the mass was surgically removed and sent for histopathological examination, which revealed an 'immature' retroperitoneal teratoma. After resection, a rent was identified in the IVC, following which the IVC was clamped. On follow-up, the patient has been compliant and the prognosis is good. CONCLUSION Retroperitoneal teratoma is a very rare clinical entity in adults. Being such massive, it can remain asymptomatic to be detected incidentally. Diagnosis is made with help of radiological findings and can be confirmed after surgical resection and histopathological examination. Surgery remains the mainstay of treatment.

Abstract
Somatic malignant transformation in a germ cell tumor (GCT) is the development of non-germ malignancies; much of available literature refers to teratoma with malignant transformation (TMT). There are various transformation histologies such as sarcoma, adenocarcinoma, primitive neuroectodermal tumors, and more rarely carcinoid tumors, hemangioendothelioma, lymphoma, or nephroblastoma. The treatments of these entities include surgery and/or chemotherapy. A standard approach in choosing chemotherapy in TMT cases has not yet been established. Many authors suggest using chemotherapeutic agents based on the transformed histology, while others recommend GCT-oriented therapy combined with surgery as the primary treatment, reserving histology-driven chemotherapies for metastatic relapse. We report the clinical findings and the genomic profile of a mixed GCT case with somatic-type malignancy of sarcoma type. We achieved a complete radiological response with GCT-oriented chemotherapy performed as salvage therapy after sarcoma-histology therapy. In addition, molecular profiles with RNA-sequencing and exome sequencing analyses of the primary tumor and the tumor with somatic-type malignancy of sarcoma type were explored.

Abstract
Germ cell cancers are the most common solid tumors among men between 15 and 40 years. Non-seminomatous germ cell tumors (NSGCTs) represent a unique and exclusive cohort of germ cell tumor patients. Non-seminoma can harbor different histologic components. The most commonly found histologies are embryonal cell cancer, teratoma, yolk sack tumor and choriocarcinoma, as well as teratocarcinoma and seminoma, in combination with non-seminomatous germ cell tumors histologic types. The clinical definition of stage I non-seminoma is the absence of metastatic lesions on imaging and normal tumor markers. The cure rate for clinical stage I NSGCT is 99% and this can be achieved by three therapeutic strategies: Active surveillance with treatment at the time of relapse, retroperitoneal lymph node dissection or adjuvant chemotherapy. The balancing of these various strategies should always be based on an individual risk profile of NGSCG patient depending on the lymphovascular invasion of the tumor.

Abstract
BACKGROUND Testicular mixed germ cell tumors (GCTs) represent a spectrum of malignancies that differ in terms of histopathology, clinical complications, and overall outcome. A variety of aggressive combinations containing different histological types have been described among such testicular tumors. However, a histopathology characterized by a combination of teratoma and choriocarcinoma, as seen in this case, in which the teratomatous component shows a secondary transformation to chondrosarcoma, is considered very rare. CASE REPORT The patient presented with progressive hemoptysis and dyspnea secondary to bilateral pulmonary cannon-ball lesions indicative of a metastatic process. His workup was remarkable for primary testicular cancer complicated by liver metastasis and very high levels of B-HCG at more than 175 000 mlU/ml. He deteriorated quickly with no improvement following the first cycle of Etoposide/Cisplatin (EP) chemotherapy regimen and died 15 days after starting cancer treatment. Such non-seminomatous GCTs with extrapulmonary visceral metastasis associated with very high tumor markers are deemed poor risk based on the International Germ Cell Cancer Collaborative Group (IGCCCG) criteria, with a reported 5-year overall survival rate reaching up to 73%. CONCLUSIONS This case is considered unique in terms of rapid clinical deterioration and lack of improvement following the standard EP chemotherapy regimen. This unusual dramatic presentation should draw attention to the possible association between the aggressiveness of the disease and its very rare histopathology.

Abstract
BACKGROUND A teratoma is a germ cell tumor that is composed of tissue derived from two or three germ layers. Duodenal teratomas are extremely rare and have been exclusively reported in neonates and children. This is the third case of a teratoma primarily arising in the duodenum and the first case that occurred in an adult.
CASE SUMMARY A 31-year-old male presented with clinical partial gut obstruction (epigastric pain, nausea, and vomiting). The physical examination showed a palpable ill-defined mass on the left side of the abdomen. The computed tomography scan revealed a multiseptated cystic tumor at the retroperitoneal area. First, he underwent gastrojejunostomy to relieve the symptoms and was referred to a tertiary-care hospital. The second operation revealed a 10-cm solid-cystic mass originating from the third part of the duodenum and adhering to the abdominal aorta and pancreas. Segmental duodenectomy was performed. The pathological diagnosis was a mature cystic teratoma. The patient was asymptomatic at 5 mo after the operation.
CONCLUSION Duodenal teratomas are extremely rare but should be included in the differential diagnosis in patients who present with intestinal obstruction. Radiological imaging is helpful to reach the preoperative diagnosis. Multidisciplinary team planning is essential to avoid injury to the adjacent organ in duodenal operation.

Abstract
Testicular cancer is the most common solid malignancy in male adolescents and young adults, with germ cell derived seminomas and non-seminomas being by far the most common histologies. Teratoma with somatic-type malignancy is a rare chemo-resistant phenotype of testis cancer associated with poor prognosis in patients with advanced stage disease. Malignant gonadal-stromal tumors comprise 5% of testicular neoplasms and approximately 10% are malignant and considered chemo-radiation resistant. Prognostic factors and treatment strategies for these uncommon histologies are lacking.

Abstract
Testicular teratomas represent a specific entity within the group of germ-cell tumours. They may comprise elements of all three germ layers. In contrast to prepubertal benign teratomas observed in infants and adolescents, postpubertal teratomas originate from the malignant germ-cell precursor. Given the good prognosis and curability of most patients with germ-cell tumour, medical oncologists and urological surgeons must be well acquainted with the principles of teratomas management. Surgery plays the decisive part in teratomas treatment, as these tumours are resistant to radio- and, to some extent, chemotherapy. In this article we concentrate on the management of post-chemotherapy resection of teratomatous masses, with special attention to the phenomenon of 'growing teratoma syndrome' and somatic-type transformation of teratomas. To understand the nature of teratomas better, we begin with a glimpse of their biological, molecular and immunohistochemical features. Managing germ-cell tumours, teratomas in particular, in high-volume reference centres is of utmost importance to maintain and increase the survivorship rate in these patients.

Abstract
Mixed germ cell tumors (GCT) with teratoma components can transform into somatic malignancies which can include histologies outside of traditional germ cell lineages. We describe a case of an 18-year-old man with a metastatic testicular GCT with both mature and immature teratoma components containing malignant transformation into multiple histologies including PNET in the primary testicular tumor and osteosarcoma in a separate pulmonary metastatic lesion. Management with targeted chemotherapy resulted in a durable remission. This is the first reported case that we know of a patient with primary PNET malignant transformation with subsequent metastatic transformation to osteosarcoma.

Abstract
Presented herein is a case of mediastinal mature teratoma with adenocarcinomatous transformation predominantly composed of mucinous adenocarcinoma in a 25-year-old man. Disease progressed despite application of surgical removal, adjuvant radio- and chemotherapy. Further immunohistochemical stains indicated a gastrointestinal origin of the tumor. Consequently chemotherapy according to the FOLFIRI regimen was applied that resulted in good response. To our knowledge, this is the first report of a clinical remission from chemotherapy with the FOLFIRI regimen after comprehensive initial treatment with surgery, radio- and chemotherapy for a patient with teratoma with malignant transformation, highlighting the importance of choosing an appropriate chemotherapy regimen.

Abstract
A 61-year-old man had undergone resection of teratoma with a histological component of seminoma occurring in the anterior mediastinum at 26 years of age in 1978, followed by radiation treatment to the resected area. He had a recurrence tumor in the left retroperitoneum 2 years later, which was resected combined with left nephrectomy and was proved to be the same pathology as the initial tumor. At 36 years after the initial treatment, the tumor recurred in the right lung. Although he underwent surgical treatment after chemotherapy, he died due to the tumor recurrence 16 months later.

Abstract
BACKGROUND Germ cell tumors with somatic malignant transformation (GCT with SMT) are rare in children and poorly described. Data are missing to determine if therapies should target the GCT, the SMT compound, or both simultaneously. PATIENTS AND METHODS A retrospective national study was conducted in the Société Française des cancers de l'Enfant (SFCE) Centers. Medical records from patients aged 0 to 18 years diagnosed with GCT with SMT between 2000 and 2015 were analyzed. Any stages and primary sites were considered as well as synchronous and metachronous cases. RESULTS Fifteen patients were identified. Thirteen patients had synchronous GCT with SMT. In the latter cases, primaries were ovary (5), mediastinum (3), pineal gland (3), sacrococcyx (1), and parametrium (1). SMT histologies were central primitive neuroectodermal tumor (5), embryonal rhabdomyosarcomas (3) or thyroid papillary adenocarcinoma, leukemia, poorly differentiated carcinoma, mixed sarcomas, and miscellaneous histology (1 case each). Chemotherapy was targeted against the GCT (3), the SMT (6), or both components (3). The last patient received surgery exclusively. Partial or complete response to chemotherapy was observed in 5/10 assessable cases: 2/3 patients treated with GCT-dedicated chemotherapy, 3/6 patients treated with SMT-dedicated therapy, and 0/1 treated with combined therapy. In addition, 2 patients with mediastinal GCT primary had metachronous SMT, with acute myeloid leukemia and thyroid papillary adenocarcinoma, 8 months and 8 years, respectively, after the diagnoses of GCT. Two patients (1 synchronous and 1 metachronous) were cured with surgery exclusively. At the end of follow-up, 6 patients died of their disease including all 4 with postsurgical macroscopic residue. CONCLUSIONS GCT with SMT constitutes a very rare entity in children and adolescents. Surgical removal of the tumor is the cornerstone of the treatment and might be sufficient in selected cases. In the remaining cases, the best management is still unknown and should take into account both components and their respective chemosensitivity. Long-term surveillance is advised for patient with unresected teratoma as late transformation can occur.

Abstract
Background. Somatic type malignancy (STM) occurs in 2% of all germ cell tumours (GCTs). The prognosis is unfavourable and the origin is poorly understood. Pathogenetic hypotheses involve direct transformation of teratoma, origin from totipotent cancer cells, or derivation from yolk sac tumour elements. Case Presentation. A 31-year-old patient was cured from testicular seminoma clinical stage IIc by orchiectomy and cisplatin-based chemotherapy. Nine years later, he experienced a late relapse with a mass sized 5 × 6 cm located at the former metastatic site. As no remission occurred after chemotherapy with three cycles of cisplatin, ifosfamide and etoposide, the mass was surgically resected. Histologically, the specimen consisted of neurofibroma with areas of malignant peripheral nerve sheath tumour and spots with mature bone formation. FISH analysis disclosed isochromosome 12p in the majority of evaluated cells suggesting somatic type malignancy (STM) of GCT. The patient is well 1 year after surgery. Conclusion. The pathogenesis of this STM remains enigmatic. The origin from GCT was evidenced by documentation of isochromosome 12p. Unrecognized teratomatous elements in the primary and totipotent cancer cells surviving the first chemotherapy could be hypothesized to represent the origin. STM developing from seminoma cells would be another novel hypothesis.

Abstract
We present a case of a teratoma with somatic type malignancy (TSM) in the form of papillary renal cell carcinoma (pRCC) within supraclavicular and retroperitoneal lymph node metastases of a testicular pure teratoma. Resection of both masses revealed a teratoma without any other germ cell tumor component. A papillary carcinoma component was also detected intermingled with the teratomatous elements. The carcinoma cells displayed eosinophilic cytoplasm and prominent nucleoli. Groups of foamy histiocytes in the fibrovascular cores was a striking finding that brought pRCC to mind. Immunoreactivity for CK7, PAX8, AMACR, CD10, napsin, and vimentin along with morphologic findings confirmed renal cell differentiation. No radiological evidence of a primary renal cell carcinoma was found in the kidney. Consequently, pRCC arising in a teratoma was diagnosed. TSM is described as teratoma with a malignant component that is typically encountered in other organs and tissues. TSM in the form of pRCC is an extremely rare entity. Our case is the second example of a testicular germ cell tumor metastasis with a somatic malignancy in the form of pRCC. In conclusion, carcinomas of renal cell differentiation should be kept in mind as a rare form of TSM, especially in metastatic germ cell tumors.

Abstract
INTRODUCTION Up to 25% of patients with metastatic testicular germ cell tumour (GCT) are not cured by first line therapy and require treatment for refractory or relapsed disease. METHODS A literature search was conducted through PubMed, Medline, Cochrane and EMBASE from January 1950 to April 2014 for articles relating to trials of chemotherapy for patients with relapsed or refractory germ cell tumours. Relevant review papers and conference proceedings were hand searched for additional references. RESULTS A range of conventional dose chemotherapy (CDCT) regimens can provide durable remissions in 20-30% of patients at first or subsequent salvage. CONCLUSIONS This article reviews the evidence underlying commonly used salvage CDCT based on ifosfamide and cisplatin such as TIP, VIP and VeIP; other active combinations; and single agent salvage regimens. The treatment of growing teratoma syndrome and malignant transformation of teratoma will also be discussed. Companion articles will explore the role of high dose chemotherapy (HDCT) and novel targeted agents.

MATERIAL AND METHODS The multidisciplinary working group has conducted a literature search on Pubmed with keywords: adult teratoma; malignant transformation; growing teratoma; chemotherapy; surgery with focus on the different forms of adult testicular teratoma. RESULTS Teratomas of the adults are malignant and subdivided into localized and metastatic forms that may be distinguished under exclusive teratoma form, growing teratoma or teratoma with malignant transformation. The management is based on an enlarged surgical excision (testis and metastasis) with, in metastatic forms, a chemotherapy adjusted with histology. Extended follow-up beyond 10 years is necessary because of the risk of late relapse. CONCLUSIONS Testicular teratoma is a rare tumor, which is considered malignant with a potential of metastasis. The treatment is based mainly on surgical management.

Abstract
Teratoma with malignant transformation is an uncommon, very aggressive germ cell tumor that has undergone transformation of a somatic teratomatous component to a histologic type identical to a somatic malignancy. We review the clinical presentation, imaging appearances, and prognosis of this entity and highlight its aggressive behavior by reporting on three patients with metastatic testicular nonseminomatous germ cell tumor with histologically proved malignant transformation.

Abstract
Background Malignant transformation describes the phenomenon in which a somatic component of a germ cell teratoma undergoes malignant differentiation. A variety of different types of sarcoma and carcinoma, all non-germ cell, have been described as a result of malignant transformation. Case presentation A 33-year-old man presented with a left testicular mass and elevated tumour markers. Staging investigations revealed retroperitoneal lymphadenopathy with obstruction of the left ureter and distant metastases. Histopathology from the left radical orchiectomy showed a mixed germ cell tumour (Stage III, poor prognosis). The ureter was stented and four cycles of cisplatin, etoposide and bleomycin chemotherapy administered. After initial remission, the patient recurred four years later with a large retroperitoneal mass involving the renal vessels and the left ureter. Left retroperitoneal lymph node dissection with en-bloc resection of the left kidney was performed. Histopathology revealed a germ cell tumour metastasis consisting mainly of mature teratoma. Additionally, within the teratoma a papillary renal cell carcinoma was found. The diagnosis was supported by immunohistochemistry showing positivity for AMACR, CD10 and focal expression of RCC and CK7. There was no radiological or histo-pathological evidence of a primary renal cell cancer. Conclusions To the best of our knowledge, malignant transformation into a papillary renal cell carcinoma has not been reported in a testicular germ cell tumour metastasis following platinum-based chemotherapy. This histological diagnosis might have implications for potential future therapies. In the case of disease recurrence, renal cell cancer as origin of the recurrent tumour has to be excluded because renal cell carcinoma metastases would not respond well to the classical germ cell tumour chemotherapy regimens.

Abstract
Testicular teratoma typically consists of heterogeneous mixtures of diverse epithelial and stromal components. The biological nature and genetic characteristics of the fibrous stroma of testicular teratomas have not been thoroughly investigated. Chromosome 12p abnormalities are the hallmark genetic alterations of germ cell tumors. We studied chromosome 12p abnormalities in the fibrous stroma and other components of pure testicular teratomas from 32 patients using interphase fluorescence in situ hybridization. Overall, 72% (23/32) of pure testicular teratomas had chromosome 12p abnormalities. Isochromosome 12p or 12p overrepresentation independent of isochromosome 12p was detected in the fibrous stroma in 53% (17/32) and 41% (13/32) of cases, respectively. Among the 17 cases positive for isochromosome 12p, 8 (47%) also had 12p overrepresentation. In 31% (10/32) cases, the fibrous stroma showed neither 12p overrepresentation nor isochromosome 12p. Isochromosome 12p and 12p overrepresentation were identified, respectively, in the gastrointestinal-type epithelium of 14/23 (61%) and 15/23 (65%) cases; in the respiratory-type epithelium of 41% (7/17) and 41% (7/17) cases; in the squamous epithelium of 62% (8/13) and 54% (7/13) cases; and in the cartilage of 63% (5/8) and 38% (3/8) cases. Concordant chromosomal 12p abnormalities were observed between the fibrous stroma and epithelial elements of testicular teratomas. Our results indicate that the fibrous stroma of testicular teratomas frequently has genetic abnormalities similar to those of the epithelial components. Concordant chromosome 12p alterations between the fibrous stroma and epithelial elements provide further evidence that both epithelial and fibrous components of teratoma are derived from a common progenitor.

Abstract
The perioperative management of the patient with an anterior mediastinal mass (AMM) is viewed as one of the more challenging anesthetic endeavors. Diligent preoperative planning is essential and often involves imaging studies using multiple modalities, pulmonary function assessment, and minimally invasive biopsy for tissue diagnosis prior to arriving in the operating room. Anesthetic induction, often without major risks in most patients, can be catastrophic in AMM patients, with possible complications that include complete airway obstruction and cardiovascular collapse. The authors present the case of a biopsy via anterior mediastinotomy under monitored anesthesia care (MAC)/sedation in a 39-year-old man, who presented with a large AMM causing significant right heart compression without tracheobronchial involvement. This procedure was followed by definitive mass resection approximately 6 weeks later. This review will explore the following: (1) the use of MAC/sedation for AMM biopsy, (2) methods of safely securing the airway in patients undergoing definitive mass resection via median sternotomy, (3) current opinions regarding the need for preoperative pulmonary function testing in these patients, (4) current opinions regarding the need for and timing of cardiopulmonary bypass in these cases, (5) the use of intraoperative transesophageal echocardiography during resection, and (6) the characteristics of mediastinal germ-cell tumors with sarcomatous conversion. Though multiple anesthetic methods have been proposed for the management of patients undergoing tissue biopsy and resection of an AMM, this case report presents 2 successful anesthetic options for 2 distinct surgical procedures. In every instance, the anesthetic management options must be tailored to the unique physiological needs of the patient presenting for surgery.

Abstract
Malignant transformation of germ cell tumors into somatic malignancy is uncommon. Its presentation differs from series to series, with 43 % of adult cases identified within the primary tumors and the remainder at the time of relapse or in the metastasis. Patients with stage I disease enjoy an excellent prognosis; whereas in metastatic sites when not completely resectable, the somatic type malignancies suffer a dismal prognosis. Radical surgery is significant for the prospects of cure and is standard chemotherapy for germ cell tumors; a transformation-oriented treatment can be effective for these patients. A deeper understanding of the biology of this phenomenon is essential for clinicians involved in such malignancies in order to permit a better control of the disease.

Abstract
An anterior mediastinal tumor had been found in a 65-year-old woman 10 years previously, and she had been followed-up under the diagnosis of a mature cystic teratoma. Changes in the structure of the inside of the mediastinal cystic tumor were observed on a chest computed tomography image, and she was referred to our hospital for surgical intervention. The tumor was removed and was determined to be a mature teratoma. An adenocarcinoma was also observed in part of this cystic lesion. From these findings, the lesion was diagnosed as a malignant change in a mediastinal mature teratoma. Because few if any changes tend to be observed in the cystic wall of such cases, an aggressive resection of such mature cystic teratomas is therefore recommended.

Abstract
Background. Teratoma with malignant transformation (TMT) is rare and most commonly encountered in adult patient with germ cell tumor (GCT). Method. We report a rare case of testicular teratoma with metastatic TMT/embryonal rhabdomyosarcoma (ERMS). A 44-year-old man underwent right orchiectomy which revealed a malignant teratoma, he subsequently had right pneumonectomy with two pulmonary masses containing a high-grade embryonal rhabdomyosarcoma. The patient developed liver metastasis three months after initial diagnosis. He was treated with a chemotherapy regimen with vincristine, dactinomycin, and cyclophosphamide (VAC) alternating with vincristine and irinotecan (VI) with complete resolution of his liver lesion. The tumors were examined with a battery of cytogenetic, immunohistochemical, and molecular assays. Results. The malignant cells were immunohistochemically positive for desmin, myogenin, and MyoD1. Molecular cytogenetics of embryonal rhabdomyosarcoma tissue revealed the presence of i(12p). The tumor expressed high level of TOPO2A, TOPO1, MRP1, MGMT, BCRP, ERCC1, RRM1, and TS. Conclusion. The activity of topoisomerase inhibitors and the potential usefulness of topoisomerase expression as biomarkers should be further tested in aprospective study.

Abstract
Currently, the outcome of patients with intermediate-and poor-risk germ cell tumors at diagnosis is optimized by the use of risk-appropriate chemotherapy and post-chemotherapy surgical resection of residual masses. Currently, there is no role for high-dose chemotherapy in the first-line setting. Patients who progress on first-line chemotherapy or who relapse after an initial complete response also have a poor prognosis. In the setting of early relapse, the standard approach at most centers is conventional-dose, ifosfamide-based regimens and post-chemotherapy resection of residual masses. The treatment of patients with late relapse is complete surgical resection whenever feasible. Salvage chemotherapy for late relapse may be used prior to surgery in patients where a complete resection is not feasible. A complete surgical resection of all residual sites of disease after chemotherapy is critical for the prevention of relapse and the long-term survival of patients with advanced germ cell tumors.

Abstract
Despite an excellent prognosis even for patients with disseminated disease, about 20% to 30% of men with advanced germ cell tumors are refractory to first-line chemotherapy or experience disease recurrence after an initial remission with such treatment. Many of these are cured with conventional dose cisplatin/ifosfamide-based regimen or high-dose chemotherapy with stem cell rescue. Controversy exists regarding the optimal choice between these 2 second-line approaches, and available data for each is reviewed here. Clinical factors can help prognosticate patients, and recently an international effort developed a prognostic model for the second-line setting that can be universally applied in future studies.

Abstract
Teratoma with a malignant somatic component (MSC) is a rare phenomenon recognized when a somatic type malignancy occurs in the context of a germ cell tumor (GCT). The authors present their 29-year experience with 40 patients treated from 1981 to 2009 in their institution. The average age was 31 years. All patients underwent radical orchiectomy, which demonstrated a GCT in 19 with an MSC. The MSC was observed in the other 21 cases in metastatic sites, including lung (13), liver (3), pleura (1), mediastinum (7), supraclavicular lymph nodes (1), and retroperitoneal lymph nodes (9). The most common histologic types were rhabdomyosarcoma (n = 11) and primitive neuroectodermal tumors (n = 10), followed by adenocarcinoma (n = 9), sarcoma, not otherwise specified (n = 5), well-differentiated liposarcoma (n = 2), leiomyosarcoma (n = 2), chondrosarcoma (n = 2), nephroblastoma (Wilms’s tumor), carcinoid, malignant peripheral nerve sheath tumor, and a gemistiocytic astrocytoma with choroid plexus tumor (each n = 1). Clinical data were collected through a dedicated database and are available for all 40 cases. After a median follow-up of 37 months, 29/40 (72.5%) were alive and disease-free. Stage-specific survival was 100% for stage I, 87.5% for stage II, and 53% for stage III patients suggesting that patients with MSC confined to the testis have a good prognosis. A lower sensitivity to chemotherapy for a MSC when compared with typical GCT is reported. Surgical excision of the MSC is therefore an essential part of the management.

Abstract
OBJECTIVE • To investigate the optimal management and prognostic factors of patients with malignant transformation (MT) in germ-cell tumour (GCT) by re-evaluating Institutional series. PATIENTS AND METHODS • Patients with an MT within GCT have been identified from the institutional database and all slides have been reviewed by the referral pathologist. RESULTS • From June 1982 to October 2009, 48 patients and 13 somatic histologies have been identified. Twelve patients presented with stage I, 12 with stage II and 24 with stage III disease. All stage I patients are alive and disease-free after a median follow up of 88 months (interquartile range 38-103). • Of the 36 metastatic cases, 11 underwent GCT-oriented chemotherapy plus surgery and seven of them are currently disease-free. Three patients underwent MT-chemotherapy, one relapsed and is still under treatment. Overall, 17 patients relapsed (35%) and three of them have been rescued by GCT-chemotherapy. Five-year overall survival was 100% for stage I, 80% (95% CI 40-94) for stage II and 44% (95% CI 19-67) for stage III patients. Stage III disease at MT, incomplete surgical removal and primitive neuroectodermal tumours plus adenocarcinoma histologies were significant adverse prognostic factors for survival. CONCLUSIONS • New insights emerged into the impact of histology and chemotherapy on MT. The development of an adenocarcinoma component as well as the possible efficacy of a GCT-tailored chemotherapy in a multimodal strategy are addressed for the first time, while disease extent at transformation and extent of radical surgery are confirmed as significant prognosticators. • An international web database for registration of all cases of MT worldwide is presented.

Abstract
BACKGROUND Teratoma with a malignant somatic component (TMSC) is rare but described in adults, whereas information on pediatric presentation is sparse. PROCEDURE The Associazione Italiana Ematologia Oncologia Pediatrica identified 14 cases of TMSC. Clinical files and pathology specimens were reviewed. RESULTS The series (9 female, 5 male) showed the following disease: testis (2), sacrococcygeal (3), ovary (3), retroperitoneum (3), mediastinum (2), and foot soft tissue (1). Distribution of the somatic component was: carcinoma (4), pancreatic neuroendocrine tumor (1), neuroblastoma (3), rhabdomyosarcoma (3), rhabdomyosarcoma plus liposarcoma, chondrosarcoma, neurogenic sarcoma (1), chondrosarcoma plus neuroectodermal sarcoma (1), malignant peripheral nerve sheath tumor (1). Three patients were in stage I, four in stage II, three in stage III, and four in stage IV. All but one patient underwent surgery and only females showed carcinoma components. Nine patients relapsed or progressed and eight died. Six patients are alive and disease-free. Two patients underwent complete resection and four were treated based on transformed histologies. Relapse-free and overall survival rates were 35.7% and 42.8%, respectively (median follow-up, 31 months). CONCLUSIONS Prognosis for germ cell tumors (GCTs) containing MSC is worse than that for GCTs. The pediatric disease appears to be more heterogeneous in tumor site distribution and MSC histology than in adults. Our series suggests no effects of age, histology, or gender on outcome. Surgery has an essential role in localized disease, with complete resection highly desirable. Chemotherapy optimized for histology should include reagents directed to the somatic malignancy, if chemosensitive. Malignant GCT warrants GCT-directed chemotherapy.

Abstract
Malignant transformation of a germ cell tumor, referring to the occurrence of somatic, nongerm cell malignancy within a germ cell tumor is a rare entity. The authors report a case of malignant transformation of an unreseceted sacrococcygeal teratoma to neuroblastoma in a 6-year-old girl and discuss this case in the light of relevant literature. This case shows that complete resection of germ cell tumor is necessary to prevent malignant transformation. In addition, when malignant transformation occurs, the treatment strategy must include surgery together with histology adapted systemic chemotherapy.

Abstract
A 48-year-old male who presented with an enlarged right scrotum was diagnosed with malignant transformation of testicular teratoma. Physical examination revealed a right scrotal mass of hard consistency with no inguinal lymphadenopathy. Since prepuberty, his right testis had been larger than the left one, with no pain or tenderness. Computed tomography and bone scan revealed retroperitoneal lymphadenopathy and multiple bone metastases. Right orchiectomy was performed immediately, and a pathological examination revealed a mature teratoma associated with adenocarcinoma, showing signet ring cell differentiation. Cisplatin-based combination chemotherapy was administered; however, the metastatic lesions progressed, and the patient succumbed to the disease after 15 months. Only a few cases of primary malignant transformation of teratoma in the testis have been reported, and this is the first case report of primary malignant transformation of teratoma in the testis with signet ring cell-type differentiation.

Abstract
The development of an angiosarcomatous component in germ cell tumors is rare. Here we studied 12 cases of mediastinal germ cell tumors with an angiosarcomatous component. All patients were men with a mean age of 34 years (range, 24-49 years). No patient had a documented testicular germ cell tumor. The mean size of mediastinal tumors was 12.9 cm (range, 5.5-16.0 cm). Grossly, the tumors were cystic with variegated hemorrhagic, mucinous, and fleshy solid areas. Microscopically, all tumors were composed of germ cell tumor. The most common germ cell tumor component was teratoma (n = 10); and other germ cell tumor components included seminoma (n = 3), yolk sac tumor (n = 3), embryonal carcinoma (n = 2), and choriocarcinoma (n = 1). The angiosarcomatous component was present in primary mediastinal tumors (n = 6), metastasis (n = 3), or both primary mediastinal tumor and metastasis (n = 3). The angiosarcomatous component accounted for an average of 30% (range, 5%-95%) of the primary mediastinal tumor. In addition, other non-germ cell components, including rhabdomyosarcoma (n = 3), leiomyosarcoma (n = 1), and poorly differentiated carcinoma (n = 1), were also present in the tumors. Of the 10 patients with follow-up available, all patients developed metastasis (n = 8) or local recurrence (n = 2); 7 died of disease at a mean of 33 months (range, 21-75 months), and 3 patients were alive at a mean of 75 months (range, 5-120 months). Our findings suggest that the presence of an angiosarcomatous component in mediastinal germ cell tumor, even in a small amount, is associated with a poor clinical outcome.

Abstract
Removal of residual masses after chemotherapy in non-seminomatous germ cell tumours (NSGCTs) remains the standard of care. We evaluated in a retrospective and monocentric study potential prognostic factors. Fifty-one patients underwent surgery after chemotherapy for NSGCT. We estimated event-free survival with Kaplan-Meier method and used Cox proportional hazards regression analysis to assess the prognostic significance of risk factors. Histology of residual masses revealed fibrosis in 25 (49%), mature teratoma in 18 (35%) and viable germ cells in 8 (16%). Alpha-fetoprotein mean level at diagnosis was higher in patients with residual masses showing mature teratoma and/or viable malignant cells (P = 0.036). In multivariate analysis, poor prognosis group according to International Germ Cell Cancer Collaborative Group was associated with worse outcome compared with good and intermediate prognosis groups (hazard ratio for events = 26.4; 95% confidence interval 2.46-283.9; P = 0.006) and primary testicular NSGCT was associated with better event-free survival than extragonadal NSGCTs (hazard ratio for events = 0.04; 95% confidence interval 0.004-0.48; P = 0.01). Resection of residual masses after chemotherapy in NSGCT results in favourable long-term survival in most patients. Our results compared favourably with those reported from higher volume centres.

Abstract
The development of sarcomatous component (SC) in testicular germ cell tumor (GCT) is an uncommon phenomenon. We searched our surgical pathology files from 1985 to 2007 and identified 33 cases of testicular GCTs with SC. The average age of patients was 31 years. All patients underwent radical orchiectomy, which demonstrated a GCT in all patients except for 3 patients who had received neoadjuvant chemotherapy. All testicular GCTs contained a teratomatous component. The GCTs were pure teratomas in 3 cases, and were mixed GCTs in the other cases. The SC was observed in primary testicular tumor (n=19), in metastasis (n=11), or in both primary testicular tumor and metastasis (n=3). The average percentage of the SC in the primary testicular GCT was 32% (range: 5% to 99%). The most common histologic type of SC was rhabdomyosarcoma (n=24), followed by high-grade unclassified sarcoma (n=5), rhabdomyosarcoma admixed with high-grade unclassified sarcoma (n=2), angiosarcoma (n=1), and low-grade myxoid sarcoma (n=1). Clinical follow-up information was available for 27 patients. Of the 13 patients whose SC was limited to the testicular GCT, 2 patients died of GCT not otherwise specified at 37 and 68 months, respectively; and 11 patients were free of disease at a mean of 46 months. Of the 14 patients with a SC in the metastasis, 7 patients died of GCT not otherwise specified at a mean of 95 months, and 7 patients were free of disease at a mean of 104 months. These results suggest that patients with a SC confined to the primary testicular GCT may not have a higher risk of mortality than those at a comparable stage without a SC. However, patients with a SC in the metastasis have an increased risk of mortality.
