Tumor Recurrence at Donor Site of Pectoralis Major Myocutaneous Flap with Tumor-free Primary Oral Carcinoma.

Pectoralis major myocutaneous flap is an important option for post onco reconstruction in head and neck region. Among the several complications mentioned in the literature, tumor recurrence at the donor site of flap is late and rare complication. Tumor implantation at the donor site of flap is a possible explanation. The occurrence of this type case is rare. We are reporting a case of tumor recurrences of pectoralis major myocutaneous flap donor site without presence of index tumor or detectable systemic disease. The recurrence was operated in our case. Clinicians should be aware of this condition for better management of patients with similar presentation.
