Mesenteric fibromatosis is commonly associated with Gardner's syndrome
and familial polyposis. These lesions may have an insidious onset via
compression of the small or large intestines, or may be noted for the
first time during abdominal exploration for some other cause. Differe
ntial diagnosis may be difficult. We report a case of mesenteric fibro
matosis with two recurrences, and two cases with no evidence of tumour
recurrence.
