Sebaceous carcinoma is a cancer that begins in the sebaceous glands, small glands that are connected to the hair follicles in the skin. Sebaceous carcinomas are rare, but they are considered an aggressive cancer because they tend to spread, or metastasize, to other areas of the body. 1, May rarely occur in association with Muir-Torre syndrome, an autosomal dominant syndrome characterized by a sebaceous neoplasm (adenoma, sebaceoma or carcinoma) and occasionally keratoacanthoma associated with a visceral malignancy (Dermatol Surg 2015;41:1) Aggressive tumor with 5 year survival rate of 92.7 Sebaceous glands are small glands connected to hair follicles in the skin. They are located in any hair-bearing region of the body but are most numerous on the skin of the scalp and face. The glands are responsible for producing sebum which is an oily substance that keeps hair and skin moisturized. What is sebaceous carcinoma What is sebaceous carcinoma? Also called sebaceous gland carcinoma, sebaceous gland adenocarcinoma, or meibomian gland carcinoma. Sebaceous (suh-bey-shuhs) carcinoma (SC) is a rare skin cancer.

The report presents a case of a 67-year-old female with a long-standing lump on the scalp. After its excision the histopathology revealed consistency with eccrine mucinous carcinoma. These neoplasms are quite rare with only around 100 cases reported since 1951. The report concludes the importance of encouraging follow-up of cutaneous lesions among patients as well as ongoing research to better. INTRODUCTION. Sebaceous carcinoma (SC) is a rare tumor that grows in the adnexal epithelial cells of the sebaceous glands. It accounts for 0.7% of all skin cancers [1-3].Risk factors for SC include advanced age, female sex, and Asian race [].SC can be classified as ocular SC (OSC) or extraocular SC (EOSC) depending on the location of its occurrence Sebaceous gland carcinoma is a rare tumor, with approximately 75% occurring in the periocular region. [] In the United States, sebaceous gland carcinoma is the fourth most common eyelid tumor after basal cell carcinoma, squamous cell carcinoma, and melanoma, and it represents 1-5% of eyelid malignancies. [2, 3] This tumor is more common in Asian countries, reportedly comprising 33% of eyelid.
