Abstract

Background: Basal cell carcinomas (BCC) arising on the genitalia are exceedingly rare with an unclear pathogenesis.

Objective: To better understand risk factors, tumor characteristics, and the possible role of human papillomavirus (HPV) in the development of BCC of the genitalia.

Methods: 1543 records of Mohs micrographic surgery performed during a 6-year period were reviewed to identify cases of BCC arising on the genitalia. Tumor tissue was analyzed for HPV DNA by in situ hybridization.

Results: Four patients with BCC of the genitalia were treated with Mohs micrographic surgery. The malignancies were located on the scrotum, perineum, and perianal areas in the three male patients and on the vulva in the female patient. The mean age was 67 years. None of the patients had prior history of skin cancers. Histologic evaluation of the tumors revealed two nodular subtypes, one superficial subtype, and one with follicular differentiation. In situ hybridization failed to reveal DNA of HPV types 6, 11, 16, 18, 30, 31, 33, 35, 45, 51, and 52.

Conclusion: In this small series, genital BCC occurred in an older age group with no identifiable predisposing risk factors and did not show evidence of HPV infection.
