title: Cutaneous Penile Horn.
abstract: A 70-year-old man presented with a slowly enlarging glans penis lesion measuring approximately 3 × 2 × 2 cm. On examination, the lesion was indurated with no induration of the glans penis deep to the lesion. He had no palpable lymphadenopathy. A glans sparing surgical excision was performed. Pathology demonstrated a squamoproliferative lesion with hyperkeratosis, and deep margin biopsy demonstrated no carcinoma. Cutaneous penile horns are hyperkeratotic lesions and may be associated with synchronous or metachronous squamous cell carcinoma. Surgical excision remains the mainstay of treatment, and follow-up physical examinations to assess for metachronous penile carcinoma are recommended.
