An abdominoscrotal hydrocele (ASH) is an uncommon condition characterized by cystic mass that occupies the scrotum and abdomen. The characteristic aspect is the presence of two hydrocele sacs in the abdominal cavity and the scrotum, and compression of one side causes enlargement of the other side, thereby connecting the two sacs. There are several hypotheses regarding the occurrence of ASH. However, the evidence of the hypotheses is lacking. The patient was a 52-year-old male. During observation of the right inguinoscrotal hydrocele, the patient complained of a palpable mass lesion on the right lower quadrant of the abdomen. Physical examination revealed ASH that occurred with the growth of the inguinoscrotal hydrocele. This was further confirmed by sequential imaging test thereby proposing the verification of cephalad extension of hydrocele. The surgical excision was recommended and inguinal exploration was performed under general anesthesia. No evidence of relapse was observed during the 2-year follow-up period after surgery. The present case proves the cephalad extension of hydrocele among other hypotheses on the etiology of ASH.

Pancreatic neuroendocrine tumor (Pan NET) accounts for only 1–2% of pancreatic neoplasms and <1% of tumors present as cystic lesions. A diagnosis of cystic tumor in the pancreas can be very challenging and confusing. Endoscopic ultrasound (USG) and fine needle aspiration (FNA) of these cystic lesions can help the clinician to narrow down the differential diagnosis. A multidisciplinary approach is warranted for a definitive diagnosis and optimal treatment. Here, we present to you a very rare case of Pan NET presenting as a cystic mass. A 65-year-old man was admitted with a history of abdominal pain. Laboratory tests showed increased levels of serum amylase, and other biochemical tests were normal. The patient underwent transabdominal USG and computed tomography (CT). CT showed well-defined cystic lesion in the proximal body of the pancreas. Endoscopic guided FNA (EUS-FNA) using 22 gauges was done. Cytological examination demonstrated clusters and sheets of plasmacytoid cells. EUS core needle biopsy was done which showed loose clusters of cells with fine uniformly distributed chromatin that stained positively for insulinoma associated protein-1 which was suggestive of a Pan NET. The differential diagnosis of cystic lesions in the pancreas is very difficult with conventional radiology such as CT and magnetic resonance imaging. Cytology is helpful for a pre-operative diagnosis of cystic Pan NET. A diagnosis of Pan NET in a pancreatic biopsy or FNA with limited and suboptimal material is often challenging. This unusual case highlights the importance of pre-operative workup of EUS followed by FNAC in cystic pancreatic lesions.

Objective; We present a case report regarding a 71-year-old woman with postmenopausal virilization caused by ovarian hilus cell hyperplasia and Sertoli-Leydig cell tumor who was suffered from hair loss, clitoromegaly and hirsutism. Case Report; The patient’s plasma testosterone levels were high.  In the MRI examination, a nodular formation of 20x26mm in size was observed in the right ovary. At the transvaginal ultrasound, a cystic mass of 28x28mm was seen in the right ovary. Then we performed a total laparoscopic hysterectomy and bilateral salpingo-oophorectomy. The final pathology showed a poorly differentiated Sertoli Leydig cell tumor at the right ovary and hilus cell hyperplasia at the left ovary. Sertoli-Leydig cell tumors, which are relatively less common, are extremely rare to be seen in the postmenopausal period. Conclusion; What distinguishes this case from others is that Sertoli-Leydig cell tumor and hilus cell hyperplasia may cause virilization symptoms together, in addition to its prevalence in advanced age.

Ovarian mucinous cystic tumors may be associated with various types of mural nodules, which can be classified as benign or malignant (anaplastic carcinoma, sarcoma, carcinosarcoma). However, anaplastic malignant nodules have rarely been reported. Here, we present a case of a 35-year-old woman who presented with abdominal discomfort. Ultrasonography showed a large cystic mass in the pelvic and abdominal cavities measuring 337 × 242 mm. Abdominal computed tomography revealed upper anterior and posterior uterine pelvic cystic lesions based on multiple nodule partition walls and classes. During hospitalization, the patient underwent exploratory laparotomy, which revealed a poorly differentiated ovarian malignant tumor, and subsequent surgical excision was performed. The pathological analysis of the surgical samples of the right ovary revealed a mucinous ovarian tumor, while the mural nodules were classified as anaplastic carcinoma. After surgery, the patient started receiving chemotherapy. Unfortunately, the patient died 6 months later. Mucinous tumor occurring with an anaplastic carcinoma is rare, and the current diagnostic methods are not sufficient in providing an early and accurate diagnosis. Most patients are already in the advanced stage upon diagnosis and combined with poorly differentiated pathological features, the prognosis is extremely poor. Clinicians need to improve the clinical evaluation before surgery and conduct preoperative preparation and communication to improve the prognosis of patients as much as possible.

Carcinosarcoma of the pancreas is a rare entity with poor prognosis. Here, we report a case of pancreatic carcinosarcoma in a 68-year-old male patient who underwent a pancreatoduodenectomy for a unilocular cystic mass in the head of the pancreas. Histologically, the lesion showed a biphasic tumor with a carcinoma component and a spindle cell sarcomatous component, which were intimately intermingled. Most of the carcinoma components are well-differentiated ductal adenocarcinoma with small areas of moderately to poorly differentiated ductal adenocarcinoma. The sarcomatous component is a high-grade highly cellular spindle cell tumor with frequent mitosis and apoptosis. Immunohistochemical studies demonstrated that the carcinomatous component was positive for epithelial markers and cyclin D1, and the sarcomatous component was negative for these markers while positive for vimentin, p16, and DOG1 with patchy positivity for S100. Other markers, including SOX10, CD117, Melan A, HMB45, actin, desmin, myogenin, beta-catenin, TLE1, and p53, were negative in both components. Molecular studies demonstrated that the tumor was microsatellite stable. Whole exome next generation sequencing analysis was performed and no pathogenic alterations in the genes were identified.

Highlight :A 26-year-old woman have sterile aerobic and anaerobic bacterial cultures.Pus and splenic tissue examination revealed no bacterial proliferation, while the surgery revealed a splenic abscess.Abstract:We presented a rare case, a 26-year-old woman have sterile aerobic and anaerobic bacterial cultures. Clinical examination of the patient showed a dense cystic mass in the left upper abdomen. Ultrasonography examination suspected a dermoid cyst. However, MRI examination of the abdomen showed turbid cystic lesions. The surgery revealed a splenic abscess, while pus and splenic tissue examination revealed no bacterial proliferation. Based on the literature, the patient had a good prognosis.

Abstract Background Adult cases of retroperitoneal isolated enteric duplication cyst (IEDC) are rare, with only 17 case reports in the relevant literature. We herein present a case, which was characterized by changes in intra-cystic density on computed tomography (CT), which was safely resected by laparoscopic surgery. Case presentation The patient was a 60-year-old male who received abdominal CT to investigate the cause of increased serum CA19-9 levels. CT revealed a unilocular cystic mass located in the lower right retroperitoneum. The size increased from 5 to 10 cm in three and a half years and the CT value decreased from 101 Hounsfield Units (HU) to 20 HU. We performed laparoscopic surgical resection, because the possibility that the enlargement of the lesion represented malignant transformation could not be denied. The large cystic mass firmly adhered to the appendix and its mesentery via the retroperitoneum, the appendix was resected en bloc with the cystic lesion. Microscopically, it had no communication with the appendix, and had an intestinal wall structure of muscularis mucosae and muscularis propria. The final pathological diagnosis was IEDC in the retroperitoneal space. There was no histological evidence of malignancy. Conclusion When we encounter a retroperitoneal cystic lesion, we should consider the possibility of malignancy to determine the treatment strategy and perform a careful operation without breaking the cyst wall, irrespective of the preoperative diagnosis.

Background: Cystadenomas of the seminal vesicles are benign cystic tumours, currently classified into the group of mixed epithelial-stromal tumours (MEST). Primary tumours arising in the seminal vesicles are quite rare, benign tumours being rarer than malignant ones, with only a few cases reported in the English literature since 1944. Cystadenomas represent a potential diagnostic pitfall, as they can be clinically confused with malignant neoplasms and histologically with non-neoplastic inflammatory lesions or other cystic tumours, even malignant. Objective and methods: We report a case of a 23-year-old man presenting with a cystic mass of the seminal vesicle, clinically suspected to be a malignant neoplasm. On pathological examination, a diagnosis of cystadenoma was made. Diagnostic criteria to make a diagnosis of this tumour are questionable. Therefore, we carried out a literature review in attempt to compare clinico-pathological findings of 28 cases reported in the English literature as cystadenomas of the seminal vesicle. Results: Only 28 cases of cystadenomas of seminal vesicles were reported in the English literature. The available data show the difficulty to rule out malignancy preoperatively in a patient with a solid-cystic mass in the pelvic region, and that morphological findings observed were often reported incompletely. Conclusions: The current classification appears debatable, as well as histopathological criteria to diagnose a cystadenoma of the seminal vesicle. For the proper management of these lesions, a multidisciplinary approach is mandatory. Level of evidence: Not applicable
