Recurrent desmoid tumor arising from latissimus dorsi flap: A case report.

Fibromatosis or desmoid tumor in the breast is a very rare benign soft tissue tumor. We report a case of recurrent desmoid tumor arising from latissimus dorsi flap after lumpectomy for breast carcinoma. To our knowledge, this is the first case of desmoid tumor arising from the latissimus dorsi flap. Despite its benignity, desmoid tumor is often locally aggressive, therefore timely diagnosis and proper management are very important. Imaging and pathological diagnosis as well as treatment management are discussed. High clinical suspicion and multidisciplinary approach are essential for prompt diagnosis and management. Wide surgical resection is required, but there is no consensus regarding treatment due to limited data.
