Sebaceous adenoma is a slow-growing, benign skin tumor that usually appears as a small lump on the scalp, face, or neck after the age of 50. It can indicate Muir-Torre syndrome, a genetic disorder that causes multiple sebaceous adenomas and other cancers. Surgical removal is recommended for tumors with unusual features, but for patients without Muir-Torre syndrome, removal may not be necessary. However, tumors can grow back if not completely removed.
A sebaceous adenoma is a small, slow-growing tumor that typically forms in the sebaceous glands in the skin. Sebaceous adenoma is considered a benign skin tumor, although it can grow back after surgical removal. These tumors mainly grow on the scalp, face and neck, but have been known to appear elsewhere in the body. Both men and women can develop these tumors, which usually appear after the age of 50. While often not serious, they can sometimes indicate Muir-Torre syndrome, a serious genetic disorder.
This sebaceous gland tumor usually appears as a tiny lump on the surface of the skin. Most sebaceous adenomas are less than 1 cm (0.39 inch) in diameter. Tumors larger than 5 cm (1.96 inches) have been reported.
Sebaceous adenomas are usually smooth and yellowish in color. The surface can be mottled. Sometimes these tumors can take on physical characteristics similar to those of cancerous skin tumors. Doctors often recommend the removal and biopsy of tumors with unusual features.
Although sebaceous adenomas are often not serious, they can sometimes be a symptom of Muir-Torre syndrome (MTS). This inherited disease typically causes multiple sebaceous adenomas, combined with skin cancer and other cancers. STD is considered a fairly rare disease. It can affect people of all ages, although most people who suffer from it start showing symptoms in their 50s.
STD is considered a genetic predisposition to sebaceous adenoma and multiple forms of cancer, including sebaceous carcinoma, a tumor of the sebaceous glands. Many patients develop colon cancer, reproductive cancers, or urinary tract cancers. Large cancerous tumors of the eyelids are considered common in STD patients. STDs are usually fatal in about half of the patients who develop them. Patients who have multiple sebaceous adenomas may be advised to have an MRI, CT scan, or other imaging process.
For patients who do not have Muir-Torre syndrome, there may be little need to remove the sebaceous adenoma surgically. These tumors are thought to be unable to spread or grow fast enough to cause damage to physical structures. Tumors that show no unusual features and are not indicative of STDs can be left alone.
A sebaceous adenoma can be removed if it is bothersome to the patient or for cosmetic reasons. Although considered benign, these tumors can often grow back if they are not completely removed.
