[Abdominal fibromatosis in a 58-year-old male patient].

We report on a 58 year-old male patient, in whom abdominal fibromatosis occurred 3 years after laparotomy and irradiation on account of rectal cancer. Abdominal fibromatosis are very rare tumour-like fibrous lesions of the anterior muscular abdominal wall, mainly affecting fertile females. Men, however, are only rarely affected and without age preponderance. A hereditary or mutant generalized defect of growth regulation of fibrous tissue is considered to be the cause of this disease; moreover, trauma, hormonal effects and pregnancies often play a role as cofactors. Interestingly, there is a high correlation between abdominal fibromatoses and osseous lesions of the femur, mandible and thoracic, as well as lumbar spine. In our case thoraco-lumbar Scheuermann's disease was detected.
