Steatocystoma is a medical term that refers to a type of skin cyst that contains oily or fatty fluid. There are several synonyms for this condition, including sebaceous cyst, epidermal inclusion cyst, and keratin cyst. These cysts are typically benign, but can become infected or inflamed, causing discomfort or pain. Treatment options for steatocystomas vary depending on the severity of the condition and may include antibiotics, topical creams, or surgical removal. It is important to seek medical advice if you notice any unusual lumps or bumps on your skin, especially if they are painful or grow in size. Early detection and treatment can help prevent complications from developing.
