Sebaceous horn: a rare entity

The sebaceous horns are often found on the skin surfaces that are usually exposed to the sunlight, like the face, scalp, or neck. These are raised skin lesions that are composed of dead keratin. They can be benign, premalignant or malignant. We are presenting an unusual case of seborrheic keratosis, a slow-growing horn-like mass of 3×2 cm, over the patient’s left ear pinna. Excision of the nodule was done, and histopathology confirmed the diagnosis of seborrheic keratosis with significant rete ridges. As these sebaceous horns range from benign, premalignant, or malignant, it is better to excise the nodule completely and sent it for histological studies.
