Desmoid tumor mimicking local recurrence of carcinoma of the breast

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.

Desmoid Tumor of the Chest Wall Mimicking Recurrent Breast Cancer: Multimodality Imaging Findings

Desmoid tumor of breast is a rare benign, locally aggressive tumor with a high recurrence rate. It has been associated with scar from previous breast surgery or trauma. Especially in breast cancer patients with previous operation history, it may simulate recurrent breast cancer clinically and radiologically. We presented multimodality imaging findings (ultrasound, computed tomography, magnetic resonance imaging and positron emission tomography/computed tomography) of chest wall desmoid tumor mimicking recurrent breast cancer in a 38-year-old patient with a history of left modified mastectomy. The desmoid tumor is a rare benign tumor that should be considered in the differential diagnosis of malignant local tumor recurrence after breast cancer operation. Biopsy was required for accurate diagnosis and wide local excision was its appropriate surgical management.
