PURPOSE To elucidate the molecular mechanisms contributing to the unique clinicopathologic characteristics of mucinous ovarian carcinoma, global gene expression profiling of mucinous ovarian tumors was carried out. EXPERIMENTAL DESIGN Gene expression profiling was completed for 25 microdissected mucinous tumors [6 cystadenomas, 10 low malignant potential (LMP) tumors, and 9 adenocarcinomas] u...

BACKGROUND The guidelines established by the National Comprehensive Cancer Network do not describe mucinous histology as a clinical factor that should influence the therapeutic algorithm. However, previous studies show conflicting results regarding the prognosis of colorectal mucinous adenocarcinoma. In this study, we described the clinicopathological features of mucinous adenocarcinoma in Japa...

In 2011,mucinous bronchioloalveolar carcinoma was reclassified as invasive mucinous adenocarcinoma, mucinous adenocarcinoma in situ,and mucinous minimally invasive adenocarcinoma.A part of the invasive mucinous adenocarcinoma of the lung differentiates to gastric mucous cells, and we term this type of carcinoma gastric-like invasive mucinous adenocarcinoma.However,treatment approaches have not ...

Mucinous tumors of the pancreas are rare and the diagnosis of invasive carcinoma can be a dilemma. While metastatic disease from mucinous cystadenocarcinoma (MCAC) and invasive intraductal papillary mucinous neoplasms (IPMN) have been reported, no extraperitoneal mucinous cystic metastatic disease has been described. When metastatic, the overall survival rates for invasive adenocarcinoma, mucin...

Background: The oncologic behavior of mucinous adenocarcinoma (MA) of colorectal differs from non-mucinous adenocarcinoma (NMA). MA is more advanced at diagnosis and has a poorer prognosis than NMA. We aimed to evaluate prognostic factors and survival rate in patients with MA compared with NMA in Western Iran. Methods: During 2008-2015 in a retrospective study, 83 patients with CRC referred to...

BACKGROUND Mucinous carcinoma of the breast is an indolent tumors with a favorable prognosis; however, micropapillary features tend to lead to aggressive behavior. Thus, mucinous carcinoma and micropapillary carcinoma exhibit contrasting biologic behaviors. Here, we review invasive mucinous carcinoma with a focus on micropapillary features and correlations with clinicopathological factors. ME...

CONTEXT Endoscopic ultrasound (EUS) with EUS-guided fine needle aspiration (EUS-FNA) has been increasingly utilized to differentiate malignant/pre-malignant pancreatic cysts from those that are benign or have low malignant potential. OBJECTIVE To determine the utility of EUS morphology, EUS-FNA cytology and cyst fluid analysis to distinguish mucinous cystic neoplasms from non-mucinous cystic ...

The goals of the study were to determine what percentage of neoplasms with a bronchioloalveolar (BAC) component were considered pure BAC by current World Health Organization (WHO) criteria. Next, we wanted to determine the number of mucinous BACs using histochemical staining with Alcian Blue PAS. Finally, we aimed to elucidate by immunohistochemistry the thyroid transcription factor-1 (TTF-1) f...

Vermiform appendix torsion is rare, and even more uncommon is the volvulus of appendiceal mucinous tumors. To our knowledge, only nine cases of torsion of the vermiform appendix associated with appendiceal mucinous neoplasms have been reported up to date. We report a case of secondary torsion of the vermiform appendix with mucinous cystadenoma in a 30-year-old man. The symptoms were consistent ...

Cystic breast mass is one of the common conditions seen presented in any breast clinic. Evaluating such cystic breast lesions is very important. Malignant cystic tumors like mucinous carcinomas and papillary carcinomas have to be differentiated from common benign cystic lesions of the breast like fibrocystic lesions and papillomas. Malignant breast cancers that present as cystic lesions are see...
