title: Metastatic spread of floor of the mouth squamous cell carcinoma via pectoralis major myocutaneous flap.
abstract: In a patient with recurrent head and neck squamous cell carcinoma, reconstruction of the floor of the mouth was carried out by transposition of a pectoralis major myocutaneous flap after composite resection. Twelve months after surgery, a chest wall metastasis corresponding to the site of the vascular pedicle was observed. It appears that the lymphatic and hematogenous tumor spread can occur along the vascular pathways of a transposed myocutaneous flap.
