T-cell predominant balanitis is described in a 38 year old uncircumcised tetraplegic man whose presenting feature was non-progressive red lesions over the inner prepuce and the glans penis without signs of infection, phimosis, or meatal stenosis. There was no regional lymphadenopathy. He was not exposed to any of the high risk factors for human immunodeficiency virus infection. As the lesion did not respond to topical antibacterial, antifungal, and corticosteroid medications applied in that order, circumcision was performed. Following circumcision, the remaining lesion over the glans penis regressed completely over a period of 1 month. Histopathology of the excised prepuce revealed that both areas of normal nonkeratinizing squamous epithelium as well as areas with hyperplasia. No atypia was noted and Bowenoid changes were not seen. Immunohistochemical studies on the inflammatory infiltrate in the excised prepucial lesion using tissue proliferation markers (PCNA and MIB-1) revealed active proliferation of the band-like infiltrate shown by immunophenotyping (anti-human T cell, CD45RO, clone UCHL1 and L26, pan-B marker) to consist predominantly of T-cells, further supporting the hypothesis of a local immune-mediated inflammatory process as the final pathogenic mechanism of the penile lesion.

Kaposi's sarcoma is a vascular tumour of multifocal origin occurring primarily on the extremities. The case of a 45-year-old HIV negative and HHV-8 positive man with an asymptomatic reddish macular lesion on the inner layer of the prepuce is described. Although primary penile Kaposi's sarcoma is a relatively uncommon disorder in HIV negative men, dermatologists and venereologists should consider this possibility when treating non-specific penile lesions. A minimal penile lesion with non-distinctive clinical features may sometimes be the exclusive manifestation of Kaposi's sarcoma, making histologic evaluation necessary to establish the diagnosis.

We present the case of an HIV-negative man with asymptomatic penile erythematoviolaceous papules associated with similar slightly verrucous papules in the interdigital space of the right foot. A biopsy of the penile lesion confirmed Kaposi's sarcoma. No other causes of immunosuppression were observed. Penile lesions of KS are rare in HIV-negative individuals but it should also be considered in the differential diagnosis. Careful follow-up is recommended.
