Massive lipoma of the palm.

Although lipomas of the hand are frequently encountered, a massive tumor involving one-half of the palm and extending into the fourth finger has been reported only once before. The case history of a 45-year-old male who underwent surgical removal of such a massive palmar lipoma is presented. Lipomas of the hand are discussed and the literature summarized. Details of the surgical evaluation and management of a massive lipoma of the hand are presented to assist other surgeons in handling similar cases.
