Sebaceous carcinoma of the forehead: Case report

Sebaceous carcinoma is a malign tumor of sebaceous glands and it is usually found on the eyelid. However, sebaceous carcinoma can arise anywhere in the body where sebaceous glands exist. Extraocular localization of the sebaceous carcinoma is rare and accounts for 25% of all cases. Sebaceous carcinoma is more common in women between the ages of 60 and 70. Moreover, Asian population is more likely to develop sebaceous carcinoma [1]. Sebaceous carcinoma usually presents as a slow growing, painless, pink-yellow papule or subcutaneous nodule [2]. Sebaceous carcinoma is locally aggressive, therefore it may metastasize to regional lymph nodes and also to distant organs [1]. On the other hand, extraocular sebaceous carcinoma is less metastatic compared to ocular sebaceous carcinoma. Because of the aggressive behaviour of the tumor, a sebaceous carcinoma should be treated with wide surgical excision [3].
