For lipomas, patients generally visit general surgery, although there are rare cases where dermatology or plastic surgery consultations may be appropriate. Lipomas are the most common type of benign tumors found on the body's surface, typically formed by an accumulation of normal adipose tissue cells and are mostly located subcutaneously, such as on the shoulders, back, buttocks, and inner thighs. Lipomas can usually be examined through ultrasound, which helps specify the location, size, and texture of the tumor, as well as preliminarily assess its blood supply. Surgical removal is the only effective treatment for lipomas, but most do not require surgery because lipomas rarely become malignant, often appear in multiples, generally do not affect appearance, and usually grow slowly, having little impact on health.
