Abstract
Tubular ectasia of the rete testis (TERT) presents as multiple cystic structures within the rete testis, often incidentally detected on ultrasound as echo-free intratesticular cystic lesions. Despite its benign nature, assessing testicular cystic lesions can sometimes be challenging. The primary importance of identifying this uncommon condition lies in its distinction from cystic testicular malignancies and thus avoiding further radical procedures. We report an instance of TERT within the right testis discovered incidentally in a patient with a medical background of epididymitis, presenting for management of left testis cryptorchidism, and bilateral inguinal hernia.

Abstract
Follicular atresia (FA) has been assumed to serve different functions in reptiles, e.g. helping to develop hierarchies, limiting clutch size, and regression of ovarian structures. Reproductive output is dependent on a balance between ovulations and FA. Excessive rates of FA may not only be detrimental for the survival of a population, but have also been associated with pathological conditions. In order to gain insights into the physiological and potentially pathological processes of FA, we performed a decriptive study on the morphological features of the ovaries in sexually mature female veiled chameleons (Chamaeleo calyptratus, VC). Of 60 clinically healthy female VC with continuous ovarian cycling and at least one confirmed cycle with FA over at least 1.5 years, 30 were selected for macroscopic evaluation of ovarian appearance and 7 were subjected to histology and immunohistology. While FA of previtellogenic follicles happened at a low rate, expected for a species with two germinal beds per ovary and polyautochronic reproductive pattern, atresia in the late vitellogenic stage affected entire generations of follicles, consequential to ovulatory failure. Histologically, no pathological processes were identified in any of the animals. Rather, three stages of FA (early, middle, late) were defined and vitellogenic follicles showed two distinct morphological types of FA: yolky and cystic. Yolky FA was found in 21/30 (70%) animals, while cystic FA co-occurred in 9/30 (30%) of the animals.

Abstract
Ovarian lesions represent a diagnostic challenge for the radiologist and should be approached according to the patient's age, menstrual cycle, and imaging characteristics. These lesions can be cystic, mixed, or solid-predominant structures. Generally, the occurrence of benign lesions surpasses that of malignant ones at a ratio of 3:1. However, within infantile and juvenile age groups, this becomes an infrequent occurrence, making up only about 5% of ovarian tumor cases. This case report sheds light on a unique scenario involving a pediatric patient who harbored 2 benign tumors simultaneously: a mature cystic teratoma and a serous cystadenoma.

Abstract
To evaluate the outcomes of robot-assisted partial nephrectomy (RAPN) for solid and cystic renal tumors. We systematically searched the Cochrane Library, PubMed, EMBASE, and Scopus databases up to March 2023. Review Manager 5.4 performed a pooled analysis of the data for random effects. Besides, sensitivity and subgroup analyses to explore heterogeneity, Newcastle-Ottawa scale, and GRADE to evaluate study quality and level of evidence. Five observational studies comprising 1353 patients (Cystic tumor: 183; Solid tumor: 1083) were included in this study. Compared to solid masses, cystic masses were associated with fewer major complications (odds ratio [OR] = 2.2; 95% confidence intervals [CI] = 1.17 to 4.13; p = 0.01). Additionally, no significant differences were observed between the two groups in terms of operative time, warm ischemia time, blood loss, hospital stay, intraoperative complications, postoperative complications, transfusion rate, postoperative estimated glomerular filtration rate (eGFR), eGFR preservation, positive surgical margin (PSM), recurrence, overall survival (OS), cancer-specific survival (CSS), recurrence-free survival (RFS) and trifecta achievement. RAPN can be performed in cystic renal tumors with perioperative, functional, and oncologic outcomes like those achievable in solid tumors. However, our findings need further validation in a large-sample prospective randomized study.

Abstract
INTRODUCTION AND IMPORTANCE Meningiomas, the most prevalent extra-axial neoplasm, are frequent tumors of the central nervous system that make up around 15 % of all intracranial malignancies. Although atypical and malignant meningiomas do exist, benign meningiomas make up the majority of cases. On both computed tomography and magnetic resonance imaging, a well-circumscribed, homogeneously enhancing, extra-axial mass is a typical imaging feature. An associated cyst is a rare imaging characteristic that may make it challenging to differentiate the tumor from a primary intra-axial glial neoplasm. Peritumoral edema can also lead to false positive results. CASE PRESENTATION A 64-year-old female patient presented to the emergency department of our hospital due to difficulty of the speech with a 3-week duration associated with unilateral headache, gait unsteadiness, and urinary incomitance. Neuroimaging of the brain by magnetic resonance imaging (MRI) with and without gadolinium contrast revealed an extra-axial cystic lesion located in the left fronto-temporal area, measuring about 4 cm × 4 cm × 4 cm. The patient underwent a craniotomy for removal of the lesion and the resected tissue was sent to pathology. Histopathological assessment revealed a pure cystic meningioma. CLINICAL DISCUSSION Cystic meningioma's preoperative diagnosis is not often easy to make. Compared to CT screening, brain MRI with gadolinium offers a higher diagnostic yield. To confirm the category and subtype of the tumor, a histopathological assessment of the tumor cells should always be performed. CONCLUSION Although its rare, cystic meningioma should be considered in the differential diagnosis of cystic brain lesions.

Abstract
INTRODUCTION AND IMPORTANCE Peritoneal inclusion cyst is a rare benign condition with low potential for malignant transformation but high recurrence rates. Debulking surgery is the recommended first line management for these patients, however, recurrence rates are up to 50 % (Padmanabhan et al., 2020; Chapel and Husain, 2021). CASE PRESENTATION A 26-year-old male being worked up for non-specific abdominal pain with cross-sectional imaging showing multiple multicystic lesions in the abdomen and pelvis. There was a pre-operative suspicion of Pseudomyxoma Peritonei and decision was made for diagnostic laparoscopy and biopsy. Mucin and an abnormal small bowel mesentery was found intraoperatively and sampled leading to the diagnosis of peritoneal inclusion cyst. CLINICAL DISCUSSION Treatment of peritoneal inclusion cyst range from surveillance to aggressive treatment with complete cytoreductive surgery with involved field peritonectomy and hyperthermic intra-peritoneal chemotherapy. CONCLUSION First line management of peritoneal inclusion cysts is for debulking surgery. Arguments for less invasive and more aggressive management has been proposed, however, further data needs to be collected to determine gold standard of treatment.

Abstract
PURPOSE The purpose of this study was to retrospectively evaluate the clinical, arthroscopic and radiological outcomes of autologous osteoperiosteal transplantation for massive cystic osteochondral defects of the talus. METHODS Cases of autologous osteoperiosteal transplantation for medial massive cystic defects of the talus between 2014 and 2018 were reviewed. The visual analogue scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) score, Foot and Ankle Outcome Score (FAOS), and Ankle Activity Scale (AAS) were assessed preoperatively and postoperatively. The Magnetic Resonance Observation of Cartilage Tissue (MOCART) system and the International Cartilage Repair Society (ICRS) score were evaluated after surgery. The ability to return to daily activity and sport, as well as complications, were recorded. RESULTS Twenty-one patients were available for follow-up, with a mean follow-up of 60.1 ± 11.7 months. All subscales of preoperative FAOS had significant (P < 0.001) improvement at the final follow-up. The mean AOFAS and VAS scores significantly (P < 0.001) improved from 52.4 ± 12.4 preoperatively to 90.9 ± 5.2 at the last follow-up and from 7.9 ± 0.8 to 1.5 ± 0.9, respectively. The mean AAS decreased from 6.0 ± 1.4 preinjury to 1.4 ± 0.9 postinjury and then increased to 4.6 ± 1.4 at the final follow-up (P < 0.001). All 21 patients resumed daily activities after a mean of 3.1 ± 1.0 months. Fifteen patients (71.4%) returned to sports after a mean of 12.9 ± 4.1 months. All patients underwent follow-up MRI with a mean MOCART score of 68.6 ± 5.9. Eleven patients underwent second-look arthroscopy, and the average ICRS was 9.4 ± 0.8. No donor site morbidity was found in any patient during the follow-up. CONCLUSION Autologous osteoperiosteal transplantation provided favourable clinical, arthroscopic and radiographic outcomes in patients with massive cystic osteochondral defects of the talus during a minimum 3-year follow-up.

Abstract
PURPOSE We aimed to evaluate whether the heterogeneity of tuber imaging features, evaluated on the structural imaging and apparent diffusion coefficient (ADC) map, can facilitate detecting epileptogenic tubers before surgery in tuberous sclerosis complex (TSC) patients. METHODS Twenty-three consecutive patients, who underwent tuber resection at our institute, were retrospectively selected. A total of 125 tubers (39 epileptogenic, 86 non-epileptogenic) were used for the analysis. Tuber heterogeneity was evaluated, using a 5-point visual scale and standard deviation of ADC values (ADCsd). A 5-point visual scale reflected the degree of T1/T2 prolongation, presence of internal cystic degeneration, and their spatial distribution within the tuber. These results were statistically compared between epileptogenic and non-epileptogenic groups, and their performance in predicting the epileptogenicity was also evaluated by receiver operating characteristic (ROC) analysis. RESULTS A 5-point visual scale demonstrated that more heterogeneous tubers were significantly more epileptogenic (p < 0.001). Multiplicity of internal cystic degeneration moderately correlated with epileptogenicity (p < 0.03) based on the comparison between class 4 and class 5 tubers. ADCsd was significantly higher in epileptogenic tubers (p < 0.001). ROC curves revealed that a 5-point visual scale demonstrated higher area under the curve (AUC) value than ADCsd (0.75 and 0.72, respectively). CONCLUSION Tuber heterogeneity may help identify the epileptogenic tubers in presurgical TSC patients. Visual assessment and standard deviation of ADC value, which are easier to implement in clinical use, may be a useful tool predicting epileptogenic tubers, improving presurgical clinical management for TSC patients with intractable epilepsy.

Abstract
INTRODUCTION AND IMPORTANCE Leiomyoma is the most common gynecologic tumor which may show atypical locations and degenerations. Cystic degeneration is said to be found in 4 % of all degenerations. Endometriosis, the presence of endometrial glands and stroma at extrauterine sites, is a common gynaecological condition seen in 10 % to 15 % of reproductive-age women usually being associated with various degrees of fertility problems. CASE PRESENTATION 40 years old woman with P1L1A2, with secondary sub-fertility for 5 years, presented with chief complaints of dysmenorrhoea for 1 year initially around the menstrual cycle relieving with analgesics but later not limited to the menstrual cycle and pain not relieving with analgesics since 1 month. The patient underwent fertility-sparing laparoscopic removal avoiding a laparotomy and definitive hysterectomy. Manual morcellation was achieved. CLINICAL DISCUSSION Cystic degeneration is rare in Leiomyoma although it is the more common gynaecological tumor in women and is associated with endometriosis probably due to retrograde menstruation. CONCLUSIONS Laparoscopic removal of leiomyoma without laparotomy and definitive hysterectomy for a case of cystic endometriosis in a degenerated subserous myoma which to the best of our knowledge according to our search of articles on the relevant topic is the first reported case pertaining to the topic from Nepal.

Abstract
The incidence of cystic fibrosis remains constant in North America and Western Europe is 1 in 3500 live births, but survival and quality of life have improved. The cystic fibrosis population has shifted toward the adult age range with a concomitant shift in the spectrum of complications. Survival increased because of aggressive symptomatic therapy, earlier diagnosis by newborn screening, and the introduction of modulators of the cystic fibrosis transmembrane conductance regulator, so that predicted median survival age is now about 50 years. In the United States, members of low socioeconomic status populations or members of racial or ethnic minorities have benefitted less from these advances.

Abstract
INTRODUCTION Children with craniopharyngiomas (CP) can experience significant morbidities caused by extensive surgery and/or radiation. Ommaya reservoir insertion (ORI) into cystic CP represents a minimally invasive approach allowing immediate decompression and aims to avoid additional injuries. The purpose of this study was to determine the surgical outcome and relevance of upfront ORI (± intracystic treatment) for preservation of endocrine function. METHODS We performed a retrospective chart review of children with CP treated at the Hospital for Sick Children between 01/01/2000 and 15/01/2020. Endocrine function was reviewed at the time of initial surgery and throughout follow-up. New endocrinological deficits related to the index procedure were defined as immediate failure (IF), whereas postoperative duration of endocrinological stability (ES) was analyzed using the Kaplan-Meier method. The rate of IF and ES was compared between the treatment groups. RESULTS Seventy-nine patients were included and had a median age of 8.3 years (range 2.1-18.0 years); 31 were males. Fifty-three patients with upfront surgical treatment, including 29 ORI and 24 gross total or partial resections had sufficient endocrinological follow-up data. Endocrine dysfunction occurring immediately after the index procedure (IF) was observed in 15 patients (62.5%) in the resection group compared to two patients (6.8%) in the ORI group, odds ratio: 0.05 (CI: 0.01-0.26, p < 0.0001). Excluding those with immediate endocrinological deficits, mean ES after ORI was 19.4 months (CI: 11.6-34.2), compared to 13.4 months (CI:10.6-NA) after surgical resection. CONCLUSIONS Endocrine function was preserved in patients with upfront ORI (± intracystic treatment), which was confirmed as a minimally invasive procedure with an overall low morbidity profile.

Abstract
Cystic lymphangioma is a congenital benign lymphatic tumor commonly diagnosed in childhood. Cervical and axillary locations are the most usual, while retroperitoneal involvement is exceptional. Perirenal cystic lymphangioma may be revealed by urological signs or by incidental findings. Imaging plays an essential role in characterizing the tumor, however differential diagnosis with benign or malignant renal tumors is not always possible, thus requiring histological evidence. We report the case of a 50-year-old man who presented with a cystic lymphangioma of the left kidney revealed by lumbar pain with imaging features mimicking an exocortical developing renal cyst. The work has been reported in line with the SCARE criteria.

Abstract
In spite of the significant technical and technological progress in neurosurgery and the continuous discoveries by the basic research, adamantinomatous craniopharyngioma remains a significant clinical challenge. Actually, the huge size of the tumor, its multiple cystic components, the encasement of Willis' circle and optic pathways, and the invasion of the hypothalamus often prevent its safe surgical resection. Moreover, the local aggressiveness of the tumor accounts for a high risk of recurrence even after a gross total resection. For these reasons, more and more efforts are being dedicated to enhance the knowledge about AC and improve the tools for its treatment.This paper is dedicated to the most recent advances concerning the AC management. Promising, new insights come for the basic research, thanks to the updates on the role of the WNT-β-catenin pathway (important for the tumor genesis and progression, not yet developed enough for a safe target therapy in children but useful for determining the prognosis) and the inflammatory mediators (widely overexpressed, especially by the cyst of the tumor, and for which target therapies are being developed). Moreover, further factors and pathways are under investigation.Also the development of new treatment strategies accounts for the improvement of the prognosis and the quality of life of AC patients. The enhancement of the experience with the endoscopic techniques (both transsphenoidal and transventricular approaches) actually allows to perform a less invasive but effective surgery that can be coupled with new modalities of radiation therapy aiming at obtaining a reliable control of the disease and protecting the endocrinological, ophthalmological, and neurological functions. A special mention is finally deserved by the techniques specifically designed for the intracystic therapy (as cyst fenestration alone or in combination with administration of radionuclides or bleomycin or interferon-α) that are here analyzed together with the aforementioned advances.

Abstract
Introduction Cystic lymphangiomas are rare benign tumors of the lymph vessels and are usually found in children. However, abdominal cystic lymphangioma in mesocolon is extremely rare in adult patients. Presentation of case We reported a 15-year-old female with giant cystic lymphangioma of the right mesocolon. On examination, only abdominal pain was confirmed. Abdominal computed tomography (CT) showed a large multiseptated cystic mass. The patient underwent a total right mesocolic excision with the lesion. The patient recovered well on postoperative follow-up and was discharged on the fifth day. No evidence of recurrence had also been found in three months follow-up period. Discussion The diagnosis of intra-abdominal cystic lymphoma is often dismissed because the clinical symptoms are nonspecific. It is easy confusion because the ultrasound and CT scan images are relatively similar to the mesenteric and omental cysts. Sclerosing therapies may cause long-term consequences such as local recurrences with a very high proportion. Complete resection, including resection of the involved organs, is necessary. With tumors surrounding the colon, surgeons should consider performing removal block colon-lesion. Conclusion Complete tumor removal is the optimal choice for the management of intra-abdominal cystic lymphangioma. However, incomplete resection may lead to local recurrence. Intra-abdominal cystic lymphangiomas are rare benign tumors. The most common location in mesenteric small bowel, in mesocolon is extremely rare. Complete tumor removal is optimal choice for lymphangioma

Abstract
BACKGROUND Adenomyoepithelioma (AME) of the breast is a rare subtype of breast tumor. Most of AMEs reported are solid, however, cystic or prominent cystic changes are extremely rare. CASE PRESENTATION A 51-year-old woman presented a lump in the upper outer quadrant of right breast, and it was accompanied by continuous breast pain and bilateral axillary itching for more than 2 months. There were no other symptoms found. Preoperative mammography and ultrasound examination were performed. Mammography showed a noncalcified lobulated mass, and it was considered to be a benign cyst with septum on ultrasound, but ductal carcinoma of breast, adenoid cystic carcinoma could not be excluded. At first, AME was not considered preoperatively, because the imaging features of this rare tumor may vary widely, which may result in an incorrect diagnosis. But eventually, AME was diagnosed by postoperative pathology and immunohistochemistry. CONCLUSION We herein present a rare case of breast AME with prominent cystic changes. AME has no-specific imaging features, but the benign or malignant nature of the lesion might be suspected on imaging.

Surgical outcomes of robot-assisted laparoscopic partial nephrectomy for cystic renal cell carcinoma. J Robot Surg 2021; 16:649-654. [PMID: 34342799 DOI: 10.1007/s11701-021-01292-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Accepted: 07/31/2021] [Indexed: 10/20/2022]
Abstract
To compare the surgical outcomes of robot-assisted partial nephrectomy (RAPN) between patients with cystic renal cell carcinoma (cRCC) and those with solid RCC (sRCC). We retrospectively analyzed 1065 patients who underwent RAPN between 2013 and 2020 for a pathological diagnosis of RCC. Patients were divided into two groups: cRCC and sRCC. cRCC was diagnosed according to the Bosniak classification system. To minimize selection bias between the two groups, patient variables (patient characteristics) and tumor factors (such as size and complexity) were adjusted using 1:1 propensity score matching. Of the 1065 patients, 94 (9%) were diagnosed with cRCC. Bosniak categories of IIF, III, and IV were noted in 4 (4.2%), 31 (33%), and 59 (63%) patients, respectively. After matching, 83 patients each were assigned to the cRCC and sRCC groups. The operation time in cRCC tended to be longer than in sRCC but not significantly different (164 vs. 150 min, P = 0.0767). Other surgical outcomes, such as change in estimated glomerular filtration rate ( - 5.2 vs. - 7.2%, P = 0.1577), perioperative complications (14.5 vs. 15.7%, P = 0.9225), estimated blood loss (62 vs. 58 mL, P = 0.5613), or negative surgical margin status (100 vs 99%, P = 0.236), were not significantly different between the two groups. During the follow-up period of about 2 years, one and two patients showed recurrence in the cRCC and sRCC groups, respectively. The surgical outcomes of RAPN were similar between cRCC and sRCC, demonstrating the feasibility of RAPN for cRCC.

Abstract
El carcinoma primario en el conducto cístico es un tumor raro y abarca del 0.1% al 0.2% de los carcinomas del tracto gastrointestinal. Presentamos el caso de un varón con pérdida de peso e ictericia, en el que se demuestra por imagen una dilatación de vías intrahepática y extrahepática condicionada por una compresión extrínseca del colédoco. Se realiza colangiografía pancreática retrógrada endoscópica que confirma la compresión, por lo que se lleva a cabo una exploración quirúrgica que evidencia una tumoración del conducto cístico. Se realiza colecistectomía con resección de ganglios linfáticos, además de anastomosis hepatoyeyunal. La tumoración se reporta como carcinoma del conducto cístico sin involucro ganglionar. Primary cystic duct carcinoma is a rare tumor and comprises 0.1% to 0.2% of carcinomas of the gastrointestinal tract. We present a case of a male with weight loss and jaundice. Evidence is shown by imaging of intrahepatic and extrahepatic duct dilatation conditioned by extrinsic bile duct compression. An endoscopic retrograde pancreatic cholangiography was performed confirming the compression, so a surgical exploration was preformed showing a tumor of the cystic duct, a cholecystectomy with resection of regional lymph nodes, as well as a hepatic-jejunal anastomosis. The tumor is reported as cystic duct carcinoma without lymph node involvement.

Abstract
Gall bladder is known for many congenital anomalies such as duplication, intrahepatic position, floating position etc. Most of its anomalies can be detected in ultrasound examination and radiography. We report an extremely rare congenital anomaly of gall bladder as observed in a male cadaver during dissection classes. The gall bladder was totally enclosed in the right free margin of the lesser omentum, in front of the usual contents of the right free margin of lesser omentum. The size, shape and blood supply of the gall bladder were normal. Though this anomaly might not cause any functional disturbances, it might result in complications during laparoscopic cholecystectomy.

[PMID: 33415383 DOI: 10.1007/s00261-020-02925-5] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2020] [Revised: 12/14/2020] [Accepted: 12/19/2020] [Indexed: 12/19/2022]
Abstract
PURPOSE To determine the accuracy of cystic appearance within adrenal masses on contrast-enhanced CT in distinguishing pheochromocytomas and malignant adrenal tumors from adenomas. METHODS We performed a retrospective review of adult patients with pathologically proven adrenal tumors who underwent contrast-enhanced abdominal CT. There were 92 patients (mean age 64.7 years, 52 men) with 22 pheochromocytomas, 34 malignant masses, and 36 adenomas. Two abdominal radiologists independently reviewed CT images to determine the presence of cystic appearance within the adrenal masses, defined as focal regions of low attenuation within the tumor that subjectively had fluid density. RESULTS Cystic appearance was present in 12/22 (55%, 95% CI 32-76%) pheochromocytomas (mean size 5.3 cm), 15/34 (44%, 95% CI 27-62%) malignant masses (mean size 5.8 cm), and 2/36 (5.6%, 95% CI 0.7-9%) adenomas (mean size 3.2 cm). Sensitivity and specificity of cystic appearance for distinguishing pheochromocytoma or malignant masses from adenomas were 48.2% (95% CI 34.7-62.0%) and 94.4% (95% CI 81.3-99.3%), respectively. Cystic appearance was a significant predictor of tumor type (p = 0.015) even after controlling for tumor size. Reader agreement for cystic appearance was almost perfect with a kappa of 0.85. CONCLUSION Cystic appearance in adrenal tumors on contrast-enhanced CT has high specificity and low sensitivity for distinguishing pheochromocytoma and malignant adrenal masses from adenomas.

Abstract
PURPOSE Cochlear implantation became a valid hearing rehabilitation option in common cavity deformity. This study aimed to assess the audiological and speech outcomes of cochlear implantation in common cavity deformity patients and to address the surgical aspect used in this population. METHODS A comprehensive systematic literature review based on preferred reporting items for systematic reviews and meta-analyses (PRISMA) guideline from database inception through April 2020. Eighteen published articles including 138 patients with common cavity deformity met the inclusion criteria. These articles studied the surgical techniques and the audiological outcomes of cochlear implantation in patients with common cavity deformity in English language. RESULTS Trans-mastoid labyrinthotomy was the common surgical approach in these patients. The average speech intelligibility rating and categories of auditory performance scores in common cavity deformity were lower than in normal cochlea subjects (p < 0.05), and non-significant (p > 0.05) compared with other types of inner ear malformations. CONCLUSION Patients with common cavity deformity who underwent cochlear implantation showed a beneficial audiological and speech outcome. However, their performance is highly variable. Therefore, pre-operative counseling of the parents is necessary. The surgical approaches should be individualized according to clinical, radiological, and surgical findings.

Abstract
Adenomatoid odontogenic tumor (AOT) with its unique and varied presentations histologically and clinically has always been an enigma. AOTs are multifaceted in their appearance with reports pointing out to its occurrence as a synchronous tumor, a purely cystic variant or with multiple foci; however, the three commonly encountered forms are Follicular/Coronal, Extra Follicular/Extra Coronal and Peripheral variants. Here, we present a subtype of the Peripheral AOT (PAOT) seen synchronous with an intraosseous cystic variant of AOT in a 16-year-old female in the anterior mandible. This case is unique in that a PAOT occurring adjacent to a focally aggressive intraosseous cystic AOT (not associated with impacted tooth) could either be synchronous with no connection to the intraosseous component or could actually be an erupted intraosseous cystic variant with peripheral manifestation. Features of cortical expansion, perforation and displacement of teeth without resorption were seen. Histologically, all the classical features of AOT along with abundant eosinophilic amorphous fibrinous deposits, cellular vacuolization, clearing of cells, dystrophic and reactive bone formation and a cystic lining were seen. Thus, this case of PAOT would add to the myriad presentation of AOT making it one of the most often discussed odontogenic tumor.

Abstract
PURPOSE Hypervascularity is a main characteristic of pancreatic neuroendocrine tumors (PanNETs), and cystic PanNETs (CPanNETs) are unique type of PanNETs in which the microenvironment remains unknown. We aim to compare the micro-vasculature features and immune cell infiltration between CPanNETs and solid PanNETs (SPanNETs). METHODS Data of 301 SPanNET and 36 CPanNET patients from a high-volume institution were evaluated. CD4, CD8, CD11c, CD15, CD20, CD68, CD34 and α-SMA expression levels were assessed by immunohistochemistry and immunofluorescent double staining. The microvessel density (MVD) and microvessel integrity (MVI) were examined. RESULTS MVD and MVI expression levels in CPanNETs were significantly higher than those in SPanNETs (p = 0.025 and 0.0092, respectively). CPanNETs had higher proportions of T1 (p = 0.023) and G1 (p = 0.052) than SPanNETs. In SPanNETs, higher MVD occurred in stages T1, N0 and G1 than in the T2/T3, N1 and G2 subgroups. In CPanNETs, CD34-MVD was uncorrelated with the T stage or grade. Higher CD34-MVD, but not MVI, was associated with better DFS (HR 0.3209, 95% CI 0.1259-0.8176, p = 0.004). There were significantly more peritumoral infiltrating immune cells than their intratumoral counterparts (p < 0.001 for each) in CPanNETs and SPanNETs. The mean number of peritumoral CD68 + TAM in CPanNETs was significantly lower than that in SPanNETs (p = 0.008). The counts of other peritumoral immune cells did not significantly differ between CPanNETs and SPanNETs. CONCLUSIONS CPanNETs had a microenvironment distinct from that of SPanNETs, including higher CD34-MVD, higher MVI and lower TAM. This specific microenvironment structure may partially help predicting the prognosis of patients with PanNET.
