Aggressive fibromatosis (extra-abdominal desmoids) of the head and neck.

Five cases of aggressive fibromatosis of the head and neck area (extra-abdominal desmoids) are presented. The clinical and histological character of local aggressiveness of these tumours is emphasised. Radical surgery, when feasible, is the only satisfactory form of treatment. Excision of as much tumour tissue as preservation of vital structures in the area will permit can also offer worthwhile palliation.
