Sebaceous carcinoma is formed deep beneath the skin’s oil glands. This is a rare form of skin cancer and is not as prevalent or common. Patients often mistake this form of cancer for benign skin conditions, avoiding the doctor until the malignancy spreads to other areas of the body. The lungs, liver, gastrointestinal tract, and brain can be affected by sebaceous carcinoma if not diagnosed and tested early.
Sebaceous carcinoma most often affects the eyelids, but can also develop on the face, scalp, and other areas of the body. Sebaceous carcinoma presents as firm, flesh colored or yellow lumps that gradually grow over time and may eventually ooze and bleed.
