Recurrent fungating tumor and a chronic rash in an immunosuppressed transgender patient: a case of Buschke-Lowenstein condyloma and epidermodysplasia verruciformis


A transgender female in her 40s with history of HIV and testicular cancer status post-genital X-irradiation presented with a perianal mass and pruritic rash across her chest. Physical examination revealed a bulky, verrucous tumor protruding outward from the anus involving the medial buttocks. Examination of the chest and arms showed numerous guttate, pink, flat-topped papules coalescing into plaques. Clinically and histologically the lesions were consistent with Buschke-Löwenstein condyloma (BLC) and acquired epidermodysplasia verruciformis (AEDV). Buschke-Löwenstein condyloma incisional biopsy tested negative for common low- and high-risk human papillomavirus (HPV) subtypes, including 6, 11, 16, and 18, possibly implicating beta HPV subtype or a less common pathogenic subtype. The patient underwent abdominoperineal resection of the BLC, which tested positive for low-risk HPV subtypes, suggesting the possibility of multiple implicated HPV subtypes in the same tumor. This case demonstrates a possible role of beta HPV or rarer HPV subtypes in the pathogenesis of verrucous carcinoma, particularly in the setting of immunosuppression.
