To describe an additional case of cutaneous penile horn, an uncommon lesion that has been associated with penile neoplasia, particularly epidermoid carcinoma.Herein we describe a patient with cutaneous horn of the penis that had presented several years earlier. The patient underwent wide resection and biopsy of the tumor site. To date, no signs of tumor recurrence have been observed. The literature is reviewed.Cutaneous horn of the penis is an uncommon lesion, but it must be emphasized that it can progress to squamous cell carcinoma. Biopsy of the tumor site should be performed carefully and patients should undergo regular control evaluation.
