INTRODUCTION: Retrorectal cysts are rare benign lesions which are frequently diagnosed in middle-aged females. According to their origin and histopathologic features, retrorectal cysts are classified as squamous-lined (dermoid or epidermoid) cysts, postanal gut (tailgut) cysts, and rectal duplications (enteric or enterogenous cysts, enterocystomas). Described in this case report is an extremely unusual patient, a woman who simultaneously had a retrorectal cyst and an ovarian serous cystadenoma in addition to a long history of misdiagnosis and multiple unsuccessful surgeries...

We present the case of a 45 year old female patient with an incidental diagnosis of a cystic pancreatic lesion corresponding to a serous cystadenoma of 14 mm. During a 5-year follow-up (CT and MRT) the lesion tripled in size and a surgical intervention was decided upon. The lesion was thought to have a benign pathology and, in an attempt to preserve the spleen and a major portion of pancreatic tissue, a central pancreatectomy with a diversion of the remaining distal pancreas was carried out. The authors reviewed national and international publications...

Background. Malignant neoplasms arising in Meckel's diverticulum, a vitelline duct remnant, are rare yet well-documented. Case Presentation. A 53-year-old previously healthy female presented with an enlarging midline abdominal wall mass. A computed tomography scan revealed a mass involving the linea alba, bilateral rectus abdominis, and subcutaneous fat. Extensive clinical workup failed to demonstrate other lesions, except local and paratracheal/hilar lymphadenopathy. Histopathologic examination of the resected tumor demonstrated a spectrum of serous neoplasia including serous cystadenoma, papillary serous carcinoma with numerous Psammoma bodies, and a poorly differentiated component...

A 59-year-old woman was referred for investigation of a pancreatic cystic lesion. Computed tomography revealed a well-demarcated, multilocular cyst, approximately 4 cm in size, at the pancreas head. Endoscopic ultrasonography demonstrated honeycomb-like components at the cyst margin. The cyst was associated with a widely-dilated upstream main pancreatic duct (MPD). Endoscopic retrograde pancreatography demonstrated a communication between the stenotic Santorini's duct and the cyst. Aspiration cytology from the cyst demonstrated clusters of mucinous epithelial neoplasm cells...

Background Ovarian cysts, which present as neoplastic and non-neoplastic lesions, are the most common gynaecological cause of hospital admissions. Early diagnosis is difficult due to asymptomatic nature. Clinical, radiological and gross examination alone cannot distinguish benign from malignant lesions, hence, histopathological examination is important for diagnostic, therapeutic and prognostic approach. Objective The objective of the study is to analyze the spectrum of ovarian cystic lesions with their clinico-morphorgical features...

OBJECTIVES: Pancreatic serous cystadenomas (SCAs) are benign tumors. Technological advances in imaging have led to increased recognition of asymptomatic pancreatic cysts, consequently increasing the demand for cytomorphologic evaluations of cyst fluid. STUDY DESIGN: A retrospective search through the pathology archives over an 11-year period was performed to identify SCAs from pancreatectomy specimens with a presurgical pancreatic EUS-guided fine-needle aspiration (FNA)...

BACKGROUND: Incidental small pancreatic cystic lesions (PCLs) are often found on pre-operative imaging in patients undergoing orthotropic liver transplantation (OLT).While these are considered benign or of low malignant potential, the influence of immunosuppression after OLT may be of concern. The aim of this study was to observe the long term outcome of these small pancreatic cystic lesions (PCLs) in post OLT patients. METHODS: An institutional OLT database of 1,778 consecutive OLT patients from January 2000 to December 2010 was analyzed...

: Background and aims: Endoscopic ultrasound (EUS)-guided needle-based Confocal Laser Endomicroscopy (nCLE) characteristics of pancreatic cystic lesions (PCLs) have been identified in studies where the gold standard surgical histopathology was available in a minority of patients. There are diverging reports of interobserver agreement (IOA) and paucity of intraobserver reliability (IOR). Thus, we sought to validate current EUS-nCLE criteria of PCLs in a larger consecutive series of surgical patients...

Ovarian epithelial inclusions lined by mucinous epithelium are rare and of uncertain origin. Ovaries containing such inclusions were studied in 42 women. The inclusions were divided into 3 groups: serous epithelial lined with typical ciliated morphology but with distinct basophilic cytoplasmic mucin in some or all of the lining cells, those lined by typical mucinous epithelium, and those lined by a combination of typical mucinous epithelium and serous epithelium. The mean patient age was 61.5 years. Pure mucinous inclusions were found in 27 patients, serous-type inclusions with cytoplasmic mucin in 20, and mixed type in 10...

Von Hippel-Lindau disease is an autosomal dominant syndrome which occurs secondary to germline mutations in the VHL tumor suppressor gene, located on chromosome 3. Clinically von Hippel-Lindau disease is characterized by an increased risk of developing simple visceral cysts, most commonly in the pancreas and kidneys, in addition to an increased risk of developing neoplasms, often with clear cell features, in a multitude of organ systems. The most common neoplasms are cerebellar and retinal hemangioblastomas, adrenal pheochromocytomas, clear cell renal cell carcinomas, pancreatic neuroendocrine tumors, pancreatic serous cystadenomas, and endolymphatic sac tumors...

Pancreatic serous cystadenoma can be categorized into microcystic, honeycomb, oligocystic, and solid patterns based on imaging appearance. The presence of typical computed tomography (CT) features helps to differentiate serous cystadenomas from other cystic and solid pancreatic masses. Cases with atypical features present a diagnostic challenge as they can mimic malignant neoplasms. This article reviews pathophysiology, prevalence, CT features, mimickers and recommendations for management of pancreatic serous cystadenoma...
