Sebaceous adenoma
Sebaceous Adenoma
Sebaceous adenoma (/sɪˈbeɪʃəs ædɪˈnoʊmə/) is a benign tumor that originates from the sebaceous gland. The term "sebaceous adenoma" is derived from the Latin words "sebaceus" meaning "waxy" or "tallow-like", and "adenoma" meaning "glandular tumor".
Definition
A sebaceous adenoma is a small, slow-growing neoplasm that primarily occurs in the oil-producing sebaceous glands. It is typically a painless, yellowish tumor that appears on the face or scalp of middle-aged and elderly individuals.
Symptoms
The most common symptom of a sebaceous adenoma is a small, yellowish or flesh-colored nodule that appears on the skin. The nodule is typically painless and slow-growing. Other symptoms may include changes in the skin surrounding the nodule, such as redness or inflammation.
Causes
The exact cause of sebaceous adenomas is unknown. However, they are often associated with Muir-Torre syndrome, a rare genetic disorder characterized by the presence of sebaceous skin tumors and an increased risk of certain types of cancer.
Diagnosis
Diagnosis of a sebaceous adenoma typically involves a physical examination and a biopsy of the tumor. The biopsy sample is examined under a microscope to confirm the presence of sebaceous cells.
Treatment
Treatment for sebaceous adenomas typically involves surgical removal of the tumor. In some cases, additional treatment may be necessary if the adenoma is associated with Muir-Torre syndrome.
