Desmoid tumor in a scar from radical nephrectomy for renal cancer.

Desmoid tumor is a fibroblastic proliferation arising in musculoaponeurotic tissues. We report a case of abdominal desmoid tumor discovered 2 years after radical nephrectomy for right renal cell carcinoma. Surgical extirpation was performed and the patient remained well 2 years later with no evidence of disease. The possibility of desmoid tumors developing in the incised abdominal wall should be considered while following patients after surgery.
