Pulmonary metastasis from desmoid tumor of the foot

Extra-abdominal desmoid tumor is a rare tumor and only a few cases occurring in the foot have been reported. They are benign but locally aggressive, and wide local surgical excision is the treatment of choice owing to the high rate of recurrence in the lower extremities. Invasiveness into the surrounding soft tissue structures often makes wide excision difficult without compromise of function. A 30-year-old woman presented with gradually increasing swelling in the dorsal aspect of the right foot. This case had a large mass in the right foot with metastasis in lungs. Biopsy confirmed the diagnosis of extra-abdominal desmoid tumor of the foot.
