Colorectal cancer is rare in teenagers, especially without known risk factors. Colon cancer in young age is more likely to be diagnosed at advanced-stage, to present unfavorable tumor histology such as mucinous carcinoma, and poor outcome. We report a case of sporadic mucinous adenocarcinoma of the colon in a 19-year-old male patient without any risk factors. He complained of severe left abdomi...

Pancreatic cystic lesions (PCL) may be incidentally detected in up to 13.5% of patients. These represent a wide variety of lesions including mucinous cysts [intraductal papillary mucinous neoplasms (IPMN) and mucinous cystic neoplasms (MCN)] that have malignant potential. The difficulty in identifying the various PCL and their unpredictable potential for malignant degeneration makes their manag...

BACKGROUND & AIMS Cysts of the pancreas display a wide spectrum of histology, including inflammatory (pseudocysts), benign (serous), premalignant (mucinous), and malignant (mucinous) lesions. Endoscopic ultrasonography (EUS) may offer a diagnostic tool through the combination of imaging and guided, fine-needle aspiration (FNA). The purpose of this investigation was to determine the most accurat...

Mucinous pancreatic neoplasms are uncommon disorders classified as either mucinous cystic neoplasms (mucinous cystadenoma or cystadenocarcinoma) or the more recently described intraductal mucin hypersecreting neoplasms (IMHN), also termed mucinous ductal ectasia. The mucinous cystic neoplasms share many common features with IMHN's but remain distinct clinico-pathologic entities. These tumors ha...

Angiosarcoma of the ovary is rare but represents an aggressive type of malignant ovarian neoplasms. The purpose of this report is to describe the features of angiosarcoma arising in mucinous tumor that was misinterpreted as a benign vascular proliferation during the intraoperative consultation. A 45-year-old woman presented with an abdominal mass for 1 month. Exploratory laparotomy was performe...

background: metastasis and recurrence of colorectal cancer after treatment is attributed to stem cells. the aim of this study was to determine the relationship between the expression of stem cell marker cd166 in colorectal cancer by immunohistochemistry and clinicopathologic parameters.methods: from 2006 to 2012, 121 colectomy specimens of patients with colon cancer that were operated in babol ...

Tumors of the pancreas that contain substantial cystic components include mainly mucinous cystic neoplasm, intraductal papillary mucinous neoplasm, solid pseudopapillary tumor, and cystadenomas (which encompass microcystic, macrocystic/oligocystic, and rare solid serous adenomas). Microcystic adenoma of the pancreas is a tumor that is benign in nature. Malignant transformation in the tumor with...

Mucinous adenocarcinoma of the prostate gland is one of the least common morphologic variants of prostatic carcinoma. A lack of precision in the definition of these mucinous neoplasms has resulted in reports which have overstated the incidence of this lesion. Of approximately 1,600 carcinomas of the prostate gland seen at Memorial Hospital from 1963 to 1983, excluding cases with only needle bio...

Predicting the prognosis of colorectal cancer (CRC) is challenging since these tumors exhibit a wide range biological behaviors. It has been hypothesized that caudal-related homeobox gene 2 (CDX2), which vital for intestinal growth and maintenance, tumor-suppressing effect promising role in CRC but studies are still controversial. This study used immunohistochemical (IHC) staining method to det...

BACKGROUND This study was designed to investigate the clinical characteristics correlated with serum CA19-9 elevation in primary mucinous ovarian tumors and to evaluate the role of serum CA19-9 in predicting borderline or malignant tumors. MATERIAL/METHODS We retrospectively identified 27 women with pathologically-confirmed primary ovarian mucinous neoplasms (16 borderline and 11 malignant), wh...
