[Malignant recurrence of a penile cutaneous horn].

OBJECTIVES: To report one case of malignant recurrence of a cutaneous horn of the glans penis.

METHODS: We report the case of a 66-year-old male patient presenting with penile discomfort over several months. Physical examination showed a corneal lesion in the glans-penis, the biopsy of which was reported as hyperkeratosis on top of pseudoepiteliomatous hyperplasia. Partial penectomy of the glans penis was performed after recurrence three months later.

RESULTS: Pathological study of the specimen identified a microinvasive squamous cell carcinoma in the base of the lesion. The patient is disease-free after two years of follow-up.

CONCLUSIONS: We emphasize the capacity the penile cutaneous horn has to become malignant. We also point out the need for observation of these lesions after excision.
