PURPOSE The aim of this study was to assess the expression of metabolism-related proteins including glucose transporter 1 (Glut-1), carbonic anhydrase IX (CAIX) and monocarboxylate transporter 4 (MCT4) in breast mucinous carcinoma and to evaluate the implications of the results. METHODS Immunohistochemical staining for Glut-1, CAIX, and MCT4 was performed on tissue sections from 59 cases of m...

Perianal Mucinous Adenocarcinoma (PMA) is a rare gastrointestinal malignancy, known to occur in patients with long-standing history of recurrent perirectal abscesses or chronic fistula. In this case report, we present unique presentation perianal mucinous adenocarcinoma, which began as rectal abscess and progressed skip lesion all the way up mid-rectal region. To best our knowledge, first PMA p...

A 56-year-old male patient with locally advanced mucinous rectal cancer underwent neoadjuvant chemoradiotherapy. Follow-up imaging with positron emission tomography-computed tomography (PET-CT) revealed a local response to chemoradiotherapy, whereas diffusion-weighted magnetic resonance imaging (DW-MRI) showed newly presented sacral bone metastasis. Histopathologically confirmed bone metastasis...

A rare case of mucinous adenocarcinoma of the cecum in a pregnant woman is described. A 32-year-old Korean woman was diagnosed as having an abdominal tumor immediately after giving birth. Abdominal computed tomography demonstrated a smooth mass measuring 10 cm in diameter on the right side of the abdomen. Acute abdomen developed 3 days after birth. At emergency surgery, volvulus of a polypoid t...

Intraductal papillary mucinous neoplasms are known malignant lesions of pancreas but recently a similar tumor has been reported and recognized by WHO in 2010 which involves the bile ducts. The involvement of common bile duct by this malignant tumor is extremely rare. Intraductal papillary mucinous tumors of bile ducts have been found to have much better prognosis than the other cholangiocarcino...

BACKGROUND This retrospective study was conducted to investigate the relationship between epidermal growth factor receptor (EGFR) mutation and histological subtypes of lung adenocarcinoma according to the International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society (IASLC/ATS/ERS) classification in Chinese patients. METHODS Three hundred and se...

Epithelial ovarian cancer comprises three major histolÃ3gica! subtypes (serous, mucinous, and endometrioid), and it is becoming clear that the developmental pathways for these subtypes are fundamentally different. In particular, endometrioid ovarian cancers probably arise by the malig nant transformation of ectopie endometrial implants called endometriosis and not the ovarian surface epithelium...

Urothelial carcinoma with abundant myxoid stroma is a newly-described and extremely rare entity. Since only very few cases have been reported, there is no consensus on its nomenclature. Microscopic examination revealed invasive urothelial carcinoma with widespread low-grade noninvasive areas. There were focal invasive areas in the neighborhood of the renal parenchyma. Malignant urothelial tumor...

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...
