 Abstract

- Herein, we present two cases of Brenner tumor, a rarely occurring neoplasm in the ovaries, obtained via intraoperative fine needle aspiration. The borderline Brenner tumor exhibited marked squamous metaplasia, characterized by individually distributed atypical squamous cells. A benign Brenner tumor associated with mucinous cystadenoma evidenced typical mucinous metaplastic features and transitional foci. These distinctive features may prove helpful in differential diagnosis of varied ovarian tumors, and particularly for intraoperative consultation.

- BACKGROUND
JC virus (JCV) is a polyomavirus that commonly infects humans and can cause progressive multifocal leukoencephalopathy in immunocompromised patients. Recently, many reports have documented detection of JCV in gastrointestinal tract cancers. We investigated the presence of JCV in gastric adenocarcinoma, adenoma, and non-neoplastic gastric mucosa.
METHODS
We selected paraffin-embedded tissue from endoscopic mucosal resections performed from January 2007 to September 2008. DNA was extracted from the paraffin-embedded specimens of 30 adenocarcinomas, 20 adenomas of the stomach, and 20 non-neoplastic gastric mucosa. Polymerase chain reaction amplifications were performed using gene-specific primers to detect the JCV gene sequences, and immunohistochemical staining was performed to detect the T-antigen (T-Ag) protein.
RESULTS
The T-Ag sequence was detected in nine of 30 gastric cancers (30%), two of 20 adenomas (10%), and eight of 20 non-neoplastic gastric mucosa specimens (40%). T-Ag protein expression was found in five of 30 gastric cancers (16.7%) and one of 20 non-neoplastic gastric mucosa specimens (5%), whereas no expression was observed in any of the adenomas.
CONCLUSIONS
Although we could not detect a correlation between JCV and gastric cancer, we demonstrated the presence of JCV T-Ag expression in human gastric cancers. These findings suggest a possible role for JCV in gastric carcinogenesis.

Abstract
PDF
- BACKGROUND
Making the diagnosis of the follicular variant of papillary thyroid carcinoma (FVPTC) is often difficult, and there are no accurate immunohistochemical or molecular markers. The purpose of this study is to evaluate performing immunohistochemistry to make the diagnosis of FVPTC.
METHODS
A total of 249 thyroid lesions were studied. We made the tissue microarray, and we assessed the expression of HBME-1, galectin-3, CD56, and p63.
RESULTS
Galectin-3, HBME-1, and p63 were positive in 79.7%, 79.7%, and 15.9% of the FVPTC, respectively. These immunohistochemical features of FVPTC were between those of classic papillary thyroid carcinoma (CPTC) and those of non-PTC. The CD56 expression was positive in 75.4% of the FVPTC, which is much higher than that of the CPTC (28.3%), and even higher than that of the non-PTC lesions (60%).
Comparing FVPTC with CPTC, the expression of galectin-3 was significantly higher and the expression of CD56 was significantly lower in the CPTCs. Comparing the FVPTC with follicular carcinoma (FC), the expression of all the markers was significantly higher in the FVPTC. Comparing PTC with FC, the expression of CD56 was lower and the expressions of the other markers were higher in the PTCs.
CONCLUSIONS
Galectin-3, HBME-1, and p63 can help make the diagnosis of FVPTC, and a cocktail of these markers can be even more useful. But CD56 is not thought to be useful to make the diagnosis of FVPTC.
