Marginal Excision of Atypical Lipoma of the Forearm

Atypical lipomatous tumor is a well-differentiated liposarcoma which is locally aggressive but does not typically metastasize. Atypical lipoma of the forearm is a very rare condition with unknown incidence. The management of atypical lipoma of the forearm is controversial, with some authors suggesting en bloc excision of the tumor. We report a case of atypical lipoma of the forearm in a 36-year-old female treated by marginal excision. The patient had no evidence of recurrence in medium-term follow-up. We conclude that marginal excision is an accepted method for the management of atypical lipoma of the forearm, which has no evidence of neurovascular encroachment.
