Extra-abdominal desmoid tumour of the leg.

Extra-abdominal desmoid tumour is a rare tumour and only a few cases occurring in the limbs have been reported. A 35-year-old woman presented with gradually increasing swelling in the upper leg. She had a mild, dull, aching pain in the tumour. Wide local excision was done and the tumour was found mainly in the subcutaneous tissue, which histopathologically proved to be an extra-abdominal desmoid tumour. This case had an abnormal radiological appearance of peripheral calcification of tumour and saucer-shaped lesion in the underlying tibial cortex. The patient had no recurrence at two years follow-up.
