title: Case report 734. Fibroma of tendon sheath eroding 3rd metatarsal bone.
abstract: A case is presented of a 37-year-old man with an extrinsic lesion originating in the soft tissue adjacent to the 3rd metatarsal and smoothly eroding the adjacent bone. The operatively confirmed diagnosis of fibroma of tendon sheath was surprising, giant cell tumour of tendon sheath eroding bone being considerably more common; these two lesions are normally impossible to distinguish radiologically.
