[Malignant tumors of the abdominal wall. 10 years of experience at the Saint-Louis Hospital].

The authors present a 10-year retrospective study of 52 patients with dermatofibrosarcomas (33 cases), sarcomas (13 cases) and desmoid tumours (6 cases) operated in their department. All these tumours were located in the abdomen or adjacent regions. Resection margins were 5 cm for dermatofibrosarcomas and 2 cm for sarcomas and desmoid tumours, with a healthy deep anatomical barrier. Dermatofibrosarcomas were repaired by direct suture in 18% of cases, directed healing in 15%, healing and graft in 45% and flap in 31% of cases. 61% of sarcomas were sutured directly, 7% were treated by directed healing and 23% required cover by a flap. All desmoid tumours were closed by primary suture. The quality of the first surgical resection remains the predominant prognostic factor.
