Extraabdominal desmoid tumors involve mainly the extremities or the chest wall, hovewer, desmoid tumors invading residual thyroid tissue are very rare.

These tumors are firm, rubbery, and have a remarkable tendency to infiltrate into surrounding structures. Although distant spread has not been documented in long-term follow-up studies, these tumors have a strong propensity to recur locally after resection. Wide radical resection with negative margins whenever possible has been considered essential to successful management. However, curative resection may be a challenge, particularly for recurrent tumors or those invading vital structures of the neck. Radiotherapy may be beneficial for tumor control in patients with unresectable tumors; those with positive margins after resection.

Our objective was to report a very rare form of this head and neck area located tumor invading residual thyroid tissue. Keywords : Desmoid, Fibromatosis, Thyroid
