Non-human papillomavirus penile squamous cell carcinoma with unusual coral-like polymorphic lesion.

Penile cancer is a rare malignancy of the male genital system. Approximately 98% of penile cancer corresponds to squamous cell carcinoma (SCC), with further morphological and molecular classification into human papillomavirus (HPV) dependent and non-HPV SCC. Compared to HPV-induced SCC, non-HPV SCC appeared to have a worse prognosis. Here, we present a case of an uncircumcised male with an unusual coral-like polymorphic lesion, and confirmed histopathology of well-differentiated non-HPV penile SCC with rapid growth progression.
