Volume 9, Number 1Reviews in UrologySolitary Fibrous Tumor of the Kidney: A Case Report and Review of the LiteratureCase ReviewImane KamaouiAfaf AmartiSanae BennisLaila ChbaniHinde El FatemiTaoufik HarmouchFadl TaziKaoutar ZnatiA solitary fibrous tumor (SFT) is an unusual spindle cell neoplasm that usually occurs in the pleura but has recently been described in diverse extrapleural sites. Urogenital localization is rare, and only 19 cases of SFT of the kidney have been described. We report a case of a large SFT clinically thought to be renal cell carcinoma arising in the kidney of a 70-year-old man. The tumor was well circumscribed and composed of a mixture of spindle cells and dense collagenous bands, with areas of necrosis or cystic changes noted macroscopically and microscopically. Immunohistochemical studies revealed reactivity for CD34, CD99, and Bcl-2 protein, with no staining for keratin, S-100 protein, or muscle markers, confirming the diagnosis of SFT. This tumor is benign in up to 90% of cases. The immunohistochemical study is the key to diagnosis. [Rev Urol. 2007;9(1):36-40]KidneyImmunohistochemical studyRenal neoplasmSpindle cells
Volume 13, Number 3Case ReviewAn Unusual Presentation of Primary Male Genital TuberculosisImane KamaouiMohamed AmineBrahim EddafaliA Ibn SellamZakaria DahamiSaid Mohamed MoudouniIsmail SarfUrogenital tuberculosis is a rare disease; however, it is the second most common location for tuberculosis after the lung. Currently, incidence of urogenital tuberculosis is increasing due to factors such as a higher prevalence of immunosuppression (especially that caused by human immunodeficiency virus infection) and drug abuse. Herein a new case of male genital primary tuberculosis is reported presenting as a scrotal tumor; the originality of this observation lies in its unusual pseudotumor form.
