Steatoma, also known as a sebaceous cyst, is a benign cystic growth that develops underneath the skin typically due to the obstruction of a hair follicle or oil gland. It is most commonly found on the scalp, neck, face, trunk, or back. The cyst is filled with a thick, oily substance known as sebum, which is produced by the sebaceous glands.
Steatomas vary in size and can be easily identified as round or oval-shaped lumps that are typically painless, slow-growing, and movable beneath the skin. They may feel smooth to the touch and have a yellow or white appearance. In some cases, a dark punctum may be observed at the center of the cyst, indicating the blocked hair follicle.
While steatomas are generally harmless, they can affect an individual’s cosmetic appearance or create discomfort if they become inflamed, infected, or ruptured. If infected, the cyst may become red, warm, tender, and may discharge pus. Medical intervention may be necessary in such cases.
Treatment options for steatomas typically involve surgical excision, during which the cyst and its cyst wall are removed. This ensures that the entire cyst is extracted, minimizing the risk of recurrence. The procedure is usually performed under local anesthesia and is considered a minor surgery.
In summary, steatoma is a benign cystic growth that develops underneath the skin due to the blockage of a hair follicle or oil gland. It is typically filled with sebum and commonly found on the scalp, neck, face, trunk, or back. While usually harmless, treatment may be required if the cyst becomes infected or causes discomfort.
