[Sebaceous gland carcinoma of the eyelids].

Sebaceous gland carcinoma is considered a relatively rare tumor and represents approximately 1 and 5% of all eyelid tumors. These tumors usually arise in the Meibomian glands of tarsus, in the Zeis glands, and the sebaceous glands of caruncle or eyebrow. In some instances it had multicentric origin, while in other cases the initial location was unable to be determined.
