Lipoma is a neoplasm of normal fat-like tissue and is prevalent in the limbs and trunk. The boundary of lipoma is clearer, the lesion is lobulated, the texture is softer and painless, and some of the lipoma can also show pseudocysticity. Typically, lipomas grow slowly, but some can grow to a large size. If a lipoma is small and asymptomatic, it may be considered for observation and left untreated for the time being. Often lipomas presenting with symptoms of compression require surgical excision, which can be performed on an outpatient basis as a day surgery. Specimens removed after surgery are routinely sent for pathologic examination.
