Final answer:
A steatoma is a benign, slow-growing cyst, also known as a sebaceous cyst, resulting from the accumulation of sebum due to blocked or damaged sebaceous glands or ducts, and can occur anywhere on the body.
Step-by-step explanation:
A steatoma, commonly known as a sebaceous cyst, is a benign lump that forms under the skin as a result of the accumulation of sebum, a secretion of the sebaceous glands. This type of cyst can occur anywhere on the body, but is most commonly found on the scalp, face, neck, and torso. Steatomas develop when the sebaceous gland or its duct becomes blocked or damaged. This blockage can be due to several factors, such as swelling from acne or skin injuries.
Sebaceous cysts are generally slow-growing and painless, and they may remain stable in size or gradually increase over time. While they are usually not harmful, they can become inflamed or infected, potentially requiring medical treatment. In some cases, people choose to have them removed for cosmetic reasons or because they cause discomfort. To accurately diagnose a steatoma, a doctor may perform a physical examination and, if necessary, a biopsy to rule out other conditions.
