Biliary cystadenoma represents a rare benign cystic hepatic neoplasm with premalignant potential. The diagnosis is usually difficult, and imaging methods may not be possible to clarify the pathology. It can be hard to determine, particularly in patients with a previous cancer history that has high metastatic potential in the liver. We presented a 53-year-old man with a newly diagnosed liver mas...

The clinical and pathological findings in a 42-year-old woman with cystadenocarcinoma of the liver are described. The criteria for acceptance of the diagnosis of cystadenoma of the liver or intrahepatic bile ducts are discussed and the previous literature is reviewed. Malignant change in a cystadenoma has not previously been recorded. Intestinal metaplasia with both goblet and argentaffin cells...

Biliary cystadenoma is a rare neoplasm of the biliary ductal system. Surgical management yields an excellent result. We present a case of recurrent biliary cystadenoma in the left lobe of the liver. The cyst was successfully treated with hepatic segmentectomy. The lobulated smoothly marginated septated cystic lesion noted on computed tomography (CT) were highlighted and the other imaging studie...

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 articl...

Mucinous cystadenoma (MC) of the ovary is an unilateral, multilocular cystic benign epithelial tumor. Supposed to be hormone responsive, MC reaches huge sizes during pregnancy. Aortocaval compression is common during pregnancy, especially when the pregnant woman is in the supine position. However, the compression recovers with a change in position. The authors report the first case of a huge mu...

We report a rare case of a papillary cystadenoma arising from the upper lip. This tumor was not distinctly encapsulated and had proliferated replacing the ductal epithelium. Mast cells were found not only in the stroma but also in the oncocytic epithelial layer. There was a strong immunoreaction with mitochondrial antibody in the epithelial layer. Only one case (0.9%) of papillary cystadenoma h...

Appendiceal mucocele is a rare clinical entity characterized by dilatation of the appendiceal lumen due to abnormal mucinous secretion. It may be of inflammatory or tumoral origin. It may occur as a result of mucoceles, mucosal hyperplasia, mucinous cystadenoma or mucinous cystadenocarcinoma. Mucinous cystadenoma of the appendix is the most common form, although it manifests itself in many diff...

Biliary cystadenoma is very rare non parasitic benign neoplasm of liver with less than 200 cases reported all over the world in the literature. It mainly occurs in middle aged women, slowly progressive; but cannot be differentiated from cystadenocarcinomas before surgery and should always considered Enucleation. Etiology of these tumors is unknown, but several theories have been proposed. Histo...

Cystadenoma of the liver is a rare neoplasm. Although many cystadenomas are asymptomatic, symptoms can include abdominal pain, postprandial epigastric discomfort, and nausea. Dramatic changes in hepatic imaging techniques have been helpful for diagnosing cystic lesions of the liver, such as simple cyst, hydatid cyst, cystadenoma, cystadenocarcinoma, and metastatic neuroendocrine tumors. However...

Mucinous cystadenoma of the spleen Report of a rare case Chao-Hung Hung, Chi-Sin Changchien, Shue-Shian Chiou, and Chao-Cheng Hwang Division of Gastroenterology, Department of Medicine; Department of Pathology, Chang Gung Memorial Hospital, Kaohsiung Medical Center, Kaohsiung, Taiwan. ABSTRACT A rare case of mucinous cystadenoma of the spleen is reported. The patient was a 63-year-old female wi...
