Pituicytoma with pleomorphism: A case report with cytological findings.

Pituicytoma is a rare neoplasm, arising in the posterior pituitary or in the hypophyseal stalk, and its cytological findings have not yet been well-described. We have experienced a case of pituicytoma, which was difficult to diagnose intraoperatively, because of its cellular pleomorphism. A tumor measuring 18 mm in maximum diameter was found at the sella turcica in a Japanese woman in her forties.

[The clinical efficacy of Bladder Chek NMP22 in urothelial cancer].

The purpose of this study is to investigate the clinical efficacy of a quick test for NMP22 (Nuclear Matrix Protein 22), Bladder Chek NMP22, as a screening test for urothelial cancers. The subjects include 51 cases(43 cases with pathologically confirmed bladder cancer, and 8 cases with upper urothelial cancer). Bladder Chek NMP22 revealed false positive in the urine with more than 1 x 10(5)/microliter of erythrocytes and 1 x 10(3)/microliter of white blood cells.
