Ectopic adrenal tissue in the ovary is a rare entity. We reported a case of ectopic adrenal tissue in borderline mucinous cystadenoma of the left ovary. A 22 year-old student presented with progressive abdomen distension associated with discomfort for 3 months. Imaging investigation was suggestive of mucinous left ovarian cyst. Left salpingo-oophorectomy was performed and the histopathology revealed borderline mucinous cystadenoma with an incidental finding of ectopic adrenal tissue. This is an interesting case because of its rarity and potential risk of neoplasm changes...

Mucinous cystadenomas and carcinomas of the ovary are well-established and common tumors. However, Primary retroperitoneal mucinous cystadenomas (PRMCs) are very rare. We present a 50-year-old woman referred to our institution with history of intermittent abdominal pain and palpable mass in her left flank. On CT-scan an unilocular cystic mass with thin wall measuring 171×155×108mm in the retroperitoneum was shown. Patient underwent surgical excision of the tumor. The histopathology examination showed a cystic mass with a fibrous wall and an epithelium composed of a single layer of columnar cells with mucin vacuoles compatible with PRMC...

AIM: Solid pseudopapillary neoplasm (SPN) is an uncommon pancreatic tumor characterized by solid and pseudopapillary growth patterns. We have observed SPNs can show a microcystic pattern (microcystic SPN), which has been poorly described and may be confused with microcystic neoplasms. We conducted the present study to clarify the clinicopathological and immunohistochemical features of microcystic SPNs. METHOD: We examined a consecutive series of 44 SPNs and 10 SCAs, and we classified them into 13 microcystic SPNs (29...

We describe the case of an oncocytic papillary cystadenoma with mucinous differentiation of the parotid gland in a 64-year-old male. Histologically, the tumor exhibited distinctive areas of intracystic papillary growth pattern with microcystic and macrocystic spaces containing mucinous secretions and small crystals. The cyst wall and papillary fronds were lined by oncocytic admixed with numerous mucocytes. Lymphoid tissue and invasive features were not identified. The tumor showed strong expression of CK7 and mammaglobin in oncocytes, and BRST-2 and MUC4 in mucocytes...

Malignant transformation of the fallopian tube mucosa, followed by exfoliation of malignant cells onto ovarian and/or peritoneal surfaces, has been implicated as the origin of most pelvic high-grade serous carcinoma. Whether a parallel pathway exists for pelvic low-grade serous tumors [ovarian serous borderline tumor (SBT) and low-grade serous carcinoma (LGSC)] remains to be fully elucidated. The literature is challenging to interpret due to variation in the diagnostic criteria and terminology for cytologically low-grade proliferations of the fallopian tube mucosa, as well as variation in fallopian tube specimen sampling...

OBJECTIVES: Little is known about the association between pancreatic cystic lesions (PCLs) with von Hippel-Lindau disease (VHLD). In this study, we describe the clinical presentation, type of PCLs, and risk for malignancy in PCLs in VHLD. METHODS: Patients given a diagnosis of both VHLD and PCLs were identified from electronic medical records at Mayo Clinic, Rochester, MN, from January 1, 2000, to January 1, 2016. Various demographic, clinical, and radiologic variables were recorded...

The management of pancreatic cysts is a common problem faced by physicians and surgeons. Pancreatic cysts are important because some of them are mucin-producing cysts (MPCs), which may harbor or develop pancreatic ductal adenocarcinoma. Thus, accurate classification of pancreatic cysts and diagnosis of MPCs offer a potential for the prevention or early detection of pancreatic cancer. However, the diagnosis and management of asymptomatic pancreatic cysts are complicated by 2 factors. First, incidentally detected pancreatic cysts are often misdiagnosed as branch duct intraductal papillary mucinous neoplasms...

Intra-abdominal and intra-pelvic pathologies initially presenting in extra-abdominal/pelvic locations is unusual. This spread predominantly occurs with infectious processes to sites including the buttock, thigh, and calf. The routes of extension into adjacent anatomically weak compartments include the pelvic outlet, greater sciatic foramen, obturator foramen, inguinal or femoral canal, weak bones, or along nerves and blood vessels. Malignant neoplasms of the appendix, while extremely rare and accounting for only 0...

Tumors of the appendix are extremely rare and constitute about 0.4% of all tumors of the gastrointestinal tract. The most common benign neoplasm is mucinous cystadenoma, which can be found in 0.6% of all excised appendices and it rarely produces any symptoms. We present the case of a female patient who underwent surgery in the Department of Surgery due to suspicion of an appendicular abscess. On the postoperative pathology study, the diagnosis of a tumor of the appendix (mucinous cystadenoma) was made. Mucinous cystadenoma is rarely included in the differential diagnosis of a non-specific abdominal pain accompanied by non-characteristic laboratory test results and imaging studies...

BACKGROUND: The term mucocele refers to the dilatation of the appendix due to mucus, and it is an uncommon disorder with an estimated incidence of 0.2%-0.3% of all appendectomies performed and 8%-10% of all appendiceal tumors. It is often asymptomatic, but may manifest appendicitis-like symptoms. METHODS: Twenty-six patients (14 females and 12 males) were operated on due to mucocele of the appendix. Sixteen patients exhibiting the characteristics of clinically acute appendicitis required an emergency operation...

REVIEW
James J Farrell
Pancreatic cysts, especially incidental asymptomatic ones seen on noninvasive imaging such as CT or MR imaging, remain a clinical challenge. The etiology of such cysts may range from benign cysts without any malignant potential such as pancreatic pseudocysts and serous cystadenomas to premalignant or frankly malignant cysts such as mucinous cystic neoplasms, intraductal papillary mucinous neoplasms, cystic degeneration associated with solid tumors such as pancreatic ductal adenocarcinoma or pancreatic endocrine neoplasms, and solid pseudopapillary neoplasms...

The aim of this study was to assess short-term outcomes of surgical treatment of pancreatic cystic tumors (PCTs). MATERIAL AND METHODS: We retrospectively reviewed medical records of 46 patients (31 women and 15 men) who had undergone surgery for pancreatic cystic tumors in our department. RESULTS: Pancreatic cystic tumors were located within the pancreatic head (21), body (11), tail (13), and whole pancreas (1). The following surgical procedures were performed: pancreatoduodenectomy (20), central pancreatectomy (9), distal pancreatectomy (3), distal pancreatectomy with splenectomy (3), distal extended pancreatectomy with splenectomy (2), total pancreatectomy (1), duodenum preserving pancreatic head resection (1), local tumor resection (4), and other procedures (2)...

Carbohydrate antigen 19-9 (CA 19-9) is a tumour marker found to be elevated in some ovarian tumours. We share our experience with a 55-year-old postmenopausal lady with unusually high CA19-9 levels arising from a benign mucinous cystadenoma of the ovary. The levels returned to normal eight weeks following staging laparotomy and a total abdominal hysterectomy with bilateral salpingo-oopherectomy. This report shows rare and significant elevation of CA 19-9 levels with benign mucinous cystadenomas of the ovary thus showing that women with unusually elevated tumour markers may actually harbour benign disease...

Epithelial ovarian tumors are a group of morphologically and genetically heterogeneous neoplasms. Based on differences in clinical phenotype and genetic background, ovarian neoplasms are classified as low-grade and high-grade tumor. Borderline ovarian tumors represent approximately 10%-20% of all epithelial ovarian masses. Various histological subtypes of ovarian malignancies differ in terms of their risk factor profiles, precursor lesions, clinical course, patterns of spread, molecular genetics, response to conventional chemotherapy, and prognosis...

BACKGROUND: Freezing strips of ovarian cortex before chemotherapy followed by transplantation is an experimental method to preserve fertility for reproductive-aged women with cancer. We report a case of a cancer patient who developed a mucinous cystadenoma in a grafted piece of ovarian cortex. CASE: A 32-year-old woman with a Ewing sarcoma had ovarian cryopreservation using cortical strip freezing before receiving chemotherapy. Five years later she had no ovarian function, and the strips were thawed and grafted back onto the ovary...
