Multiple Lipomas

Comments:
Multiple Lipomas: About 5% of patients with lipomas have multiple tumors. The numbers can range from a few to a few hundred. The tumors are located usually in the upper part of the body, including back, shoulders and upper arms, with a predilection for the extensor surfaces.

The lesions appear in the 5th and 6th decades of life. Rare cases have onset at puberty. There is a strong male predilection (M:F=3:1). One-third of patients with multiple lipomas have hereditary predisposition (familial multiple lipomas) usually with an autosomal dominant pattern. Multiple lipomas are a component of some well-known clinical syndromes (discussed in the next image).
