Multicentric extra-abdominal 'myofibromatosis': report of a case with ultrastructural findings

A case of multicentric extra-abdominal fibromatosis, a rare entity, arising in a young female is presented. Three separate lesions developed in the same limb over a period of 11 years, one of which recurred on two occasions. Electron microscopy of the most recent tumour showed a predominance of myofibroblasts. The literature regarding extra-abdominal fibromatosis is reviewed and discussed. Redesignation of both abdominal and extra-abdominal fibromatoses as myofibromatoses is suggested.
