Among 31 benign cystic neoplasms of the pancreas diagnosed as mucinous cystadenomas, we identified 9 (29%) cases of nonmucinous cystadenomas with a pancreatobiliary phenotype and an ovarian-like stroma. Although both cystic tumors belong to the same family, they should be separated because their epithelial lining and cyst fluid are different. The lining cells of the nonmucinous cystadenomas con...

Background. Biliary cystadenomas (BCAs) are rare, benign, potentially malignant cystic lesions of the liver, accounting for less than 5% of cystic liver tumours. We report the outcome following resection of biliary cystadenoma from a single tertiary centre. Methods. Data of patients who had resection of BCA between January 1993 and July 2014 were obtained from liver surgical database. Patient d...

INTRODUCTION Pancreatic cysts are now being encountered by primary and specialty care physicians with ever increasing frequency due to the widespread use of high quality cross-sectional imaging (1,2). The majority of these cystic lesions are incidental asymptomatic findings, and therefore can present both diagnostic and therapeutic dilemmas. The differential diagnosis of cystic pancreatic lesio...

Oncocytic cystadenoma is a benign tumor of salivary glands, histologically characterized by multicystic growth of the oncocytic epithelial lining. Crystals in different shapes and nature associate oncocytic type of salivary gland neoplasms. An 82 year-old woman with right parotideal mass had an operation of superficial parotidectomy. Histological examination revealed multiple unilocular or mult...

A 24-year-old man presented himself with a nodular lesion of about 1 cm diameter at the site of a previous orchiopexy associated with surgery for cryptorchism. Histopathology revealed the lesion to be adenomatous and confined to the scrotum. Histological and immunohistological features were not consistent neither with median raphe cysts or cutaneous adenomas nor with the intrascrotal adenomas o...

BACKGROUND AND OBJECTIVES In recent years there has been an increase in the diagnosis of cystic tumors of the pancreas. In this setting, difficult diagnostic problems and different therapeutic management can be proposed. MATERIAL AND METHODS A review of the literature and authors experience were undertaken. RESULTS Cystic tumors of the pancreas include different neoplasms with a different b...

Although little is known on the true prevalence of pancreatic cysts, physicians are currently more frequently confronted with pancreatic cysts because of the increasing use of sophisticated cross-sectional abdominal imaging. Cystic lesions of the pancreas comprise of a heterogeneous group of diagnostic entities, some of which are benign such as inflammatory pseudocysts or serous cystadenomas an...

Biliary cystadenomas are cystic hepatic tumours of biliary origin. Cystadenomas are often slow-growing benign tumours, but always harbour the risk of malignant transformation. Cystadenomas are often asymptomatic, but may present with abdominal pain and distension. Though suspected with cross-sectional abdominal imaging, definitive diagnosis almost always requires histology. Spontaneous rupture ...

Pancreatic cystic lesions (PCLs) may represent malignant or premalignant neoplasms and require diagnostic evaluation. Patient’s demographics and clinical presentation should be considered when diagnosing PCLs. Radiologically, location, ductal relation, external contour, wall, and septal enhancement give important clues for each type of lesion. Imaging features that suggest a high malignancy ris...

INTRODUCTION We suspected that paraovarian cysts of neoplastic origin may be underreported. This study was designed to evaluate our data on the pathologic characteristics of cystic lesions located in the paraovarian area and compare them with previous studies that claimed the vast majority of these lesions were simple paraovarian cysts and only few (1.69% to 5%) were neoplastic ones. METHODS ...
