[Introduction] Ovarian tumors may exhibit various morphologic appearances, and specific diagnosis on MR imaging is often difficult. 1-H MR spectroscopy (MRS) provides metabolic information, and may add valuable information for the diagnosis. The choline peak (3.2 ppm) may be observed in solid tumoral components reflecting metabolic activity of tumor cells and tend to show higher peaks in malign...

PURPOSE Mucinous adenocarcinomas account for about 10% of all colorectal cancers. This study aimed to investigate the prognostic impact of mucinous histologic subtype on oncologic outcomes in patients with colorectal cancer. METHODS This retrospective study was performed at two large tertiary university hospitals. We analyzed the characteristics, prognostic factors, and survival of patients w...

We report a case of a 44-year-old woman with bilateral ovarian carcinoma that had metastasized from the colon and mimicked primary mucinous cystadenocarcinoma. Macroscopically, both ovarian tumors were large, multiloculated cystic masses with abundant mucinous content. Histologically, they were lined with mucinous epithelium with mild to moderate nuclear atypia and showed stromal invasion and s...

Ovarian-type epithelial tumors of the testes and paratestes are very rare. Mucinous subtypes of such tumors are extremely rare; only 25 cases have been reported to date. Ovarian-type epithelial tumors are histologically classified into cystadenomas, borderline tumors, and carcinomas. We herein report a case involving a 60-year-old man with a primary borderline mucinous tumor of the testis. He u...

UNLABELLED Cystadenocarcinoma is primarily characterized by cystic structures of varying sizes, that are lined by epithelial cells. As a rare neoplasm, only four cases of cystadenocarcinoma of submandibular glands have been previously reported. Herein, we reported a unique case of submandibular gland cystadenocarcinoma in a 44-year-old man. By in large, this case had typical morphologic cystade...

Sertoli-Leydig cells tumors are rare ovarian neoplasms that can be managed with conservative resection given their generally excellent prognosis. Here we report a case of Sertoli-Leydig cell tumor mistakenly diagnosed as an invasive mucinous adenocarcinoma at time of intraoperative consultation because of its blue-mucinous appearance in the frozen section material. The patient subsequently unde...

Warshaw, A. L, Compton, C. C., Lewandrowski, K., Cardenosa, G. and Mueller, P. R. (1990) Cystic tumors of the pancreas. New clinical, radiologic and pathologic observations in 67 patiems. Annals ofSurgery, 212, 432-445. Within a 12-year period we treated 67 patients (49 women, 18 men; mean age, 61 years) with cystic neoplasms of the pancreas, including 18 serous cystic adenomas, 15 benign mucin...

The differential diagnosis for cystic lesions of the pancreas is broad and the role of EUS is becoming more clearly defined. Pancreatic cysts may be inflammatory, such as pseudocysts, in which the cyst wall lacks an epithelium. Inflammatory cells line the fluid collection, which may often be located adjacent to an area of acute or chronic pancreatitis. Other types of pancreatic cysts may be bro...

INTRODUCTION Mucinous tumors are the second most common form of epithelial ovarian tumor, yet the cell of origin for this histologic subtype remains undetermined. Although these tumors are thought to arise through a stepwise progression from benign cystadenoma to borderline tumor to invasive carcinoma, few studies have attempted to comprehensively characterize the genetic changes specific to th...

The authors report a rare case of primary mucinous carcinoma of the skin initially diagnosed as a metastatic adenocarcinoma. The tumor occurred in the right axilla in a 75-year-old man. Initial pathological diagnosis was metastatic adenocarcinoma. However, no primary focus was found in the body. The revised diagnosis by the authors was primary cutaneous mucinous carcinoma. The tumor (1.5 cm) wa...
