Ovarian clear cell adenocarcinoma producing alpha-fetoprotein: case report.

Case: We report a case of a 63-year-old woman with a ovarian clear cell carcinoma with serous component of less than 10%.

Cathepsin D expression in colorectal adenocarcinomas and adenomas.

The aim of this study was to investigate the role of cathepsin D in colorectal cancer. For this purpose cathepsin D expression was evaluated by means of immunohistochemistry in stromal and tumor cells of 31 colorectal carcinomas and 29 adenomas. Cytoplasmic cathepsin D expression of tumor cells was present in 90.
