Desmoid tumour: a pleomorphic lesion.
Desmoid tumour (DT) is an uncommon locally invasive non-metastasizing neoplastic lesion. The aetiology of this tumour is unknown and its treatment is controversial. Twelve cases of DT are presented and the literature is reviewed.



Twelve cases of DT treated at our institution during a 3.5-year period are analysed and the literature reviewed. Ten patients were referred with a primary tumour, one with local recurrence and one patient with a second primary desmoid tumour. One patient had multiple mesenteric DT (familial adenomatous polyposis coli-FAP), and in the remaining 11 patients the tumour was located in the abdominal wall in four, at an extremity in three, in the upper back in two patients, in the pelvis in one and retroperitoneally in one.



The largest mesenteric DT was marginally excised en bloc with total jejunectomy. In the remaining 11 DT, complete excision to microscopically tumour-free margins was possible in nine cases and to microscopically involved margins in two cases. At a mean follow-up of 22 months (range 7-38 months), one patient was alive with stable disease (Gardner's syndrome), 10 patients were alive and free of recurrence and one patient (9%) developed local recurrence which was re-excised-she is disease-free 10 months later.



Complete excision is the main modality of treatment for primary and recurrent DT. This is feasible in most cases except for tumours involving the base of the bowel mesentery. Surgical resection alone achieved local control of the tumour in most of the patients in this series (92%).
