Non-surgical treatment of primary female urethral cancer

Primary carcinomas of the female urethra are extremely rare, with an annual incidence of less than ten in one million. Currently, there is no consensus regarding management of this malignancy. However, there have been several case reports demonstrating the efficacy of chemoradiation in the treatment of female urethral cancer. In this report we present two cases of female primary urethral adenocarcinoma that were treated by concomitant chemotherapy and external beam radiotherapy, followed by interstitial brachytherapy

Atypical fibrous histiocytoma of the scrotum.

Atypical fibrous histiocytoma is a rare neoplasm. A scrotal location for this tumor is even more unusual. We report a case of a 90-year-old man with scrotal atypical fibrous histiocytoma. Our case had histologic features consistent with those cases previously reported in the literature. The tumor consists of cells with large hyperchromatic irregular nuclei, bizarre multinucleated cells (monster cells), and xanthomatous cells with large prominent nuclei set in a background of classic fibrous histiocytoma. Rare mitotic figures are identified. Immunohistochemical studies showed the tumor cells to be positive for vimentin, smooth muscle actin, desmin, KP-1, factor XIIIa, and MIB-1 (less than 10%). In addition to the expected immunohistochemical studies, the tumor stained diffusely positive for CD117. To our knowledge, this is the first report of atypical fibrous histiocytoma of the scrotum
