Fibromatosis (or desmoid tumor) refers to a histologically benign but locally aggressive lesion arising from musculoaponeurotic structures in various anatomic sites. The lesion arises most commonly in the abdomen; the head and neck is the site of origin in only about 10-15% of extra-abdominal fibromatosis. We report a 26-year-old male patient who presented with progressive severe trismus and a left abducens palsy. Radiographs and biopsy confirmed the presence of diffuse fibromatosis at the left skull base, arising in the infratemporal fossa with significant intraand extracranial extension. A two-stage infra temporal fossa/middle cranial fossa resection failed to completely excise the tumor, which was found to extend to the contralateral cavernous sinus and skull base. A discussion of extra-abdominal fibromatosis, with review of the pathologic and radiologie findings in this case, is presented.
