Extra-ocular sebaceous carcinoma: Rare skin adnexal tumor

Sebaceous carcinoma is a rare, highly malignant, and potentially lethal tumor of the skin, which most commonly occurs in the eyelid. The neoplasm arises from sebaceous glands, such as those of the eyebrow. It represents 1-5.5% of eyelid malignancies and is considered to be the third most common eyelid malignancy after basal cell carcinoma and squamous cell carcinoma, although few reports placed this tumor as second most common after basal cell carcinoma. Cutaneous extra-ocular sebaceous carcinoma is a rare tumor that frequently occurs on the face and scalp, constituting about 25% of all sebaceous carcinoma. It usually affects elderly women and characterized by the high rate of local recurrence, regional and distant metastases. We describe a case of sebaceous carcinoma of the left cheek in an 84-year-old male.
