A cutaneous horn is a rare, hyperkeratotic, projecting lesion that can be mostly found in sun-exposed areas of the skin. The base of the lesions can reveal an underlying malignancy. They can also be associated with several benign or pre-malignant dermatologic conditions. A biopsy of the base of the lesion and histopathological analysis are needed to confirm the diagnosis. Management depends on the underlying disease; however, surgical excision is the preferred treatment method.

The mysterious sebaceous horn (devil\'s horn) is a historically perplexing phenomenon of unknown etiology. It classically occurs on the sun-exposed areas of the face and hands and consists of a keratin mound with a benign base in most cases and squamous cell carcinoma occurring in about 20% of patients.

Sebaceous horns (de la Pena Zarzuelo et al., Arch Esp Urol 54:367-368, 2001; Vera-Donoso, Scand J Urol Nephrol 43:92-93, 2009) are rare on the penis, as they are commonly seen only on sun-exposed areas. A 45-year-old male presenting with multiple sebaceous horns of the penis is reported here. Excision of the horn with a rim of normal tissue in the base was done. Histopathological examination revealed no malignant change.
