title: Kaposi's sarcoma of the glans penis in an immunocompetent patient.
abstract: We report a 39-year-old HIV negative man with a solitary reddish-brown papule located on the glans penis, which had developed 6 months previously. Histopathologic examination showed spindle-shaped cells scattered between collagen bundles and intermingled with small, pointed vascular-like spaces. Spindle-shaped cells stained positively for antiFactor VIII and anti-CD34 antibodies. Human herpes virus-8 DNA was detected in tumor tissue and in peripheral blood mononuclear cells. Based on clinicopathologic and molecular findings, the diagnosis of classic Kaposi's sarcoma was made. Two months after the initial observation, three additional papules developed on the glans penis. Histopathologic examination of one lesion confirmed the diagnosis of classic Kaposi's sarcoma. The remaining lesions were treated with electrodessication and curettage. After a follow-up period of 6 months no evidence of recurrence was observed. We report this case for the unusual localization of Kaposi's Sarcoma in a young, HIV-negative patient.
