ABSTRACT
We report a 35-year-old Chinese woman with clear cell sarcoma of the rectus sheath aponeurosis presenting as a tender anterior abdominal mass. She was treated with wide local excision. Local recurrence and distant metastasis occurred within two months of the onset of the complaint. Clear cell sarcoma is a rare cancer with a propensity for slow progressive invasion. They occur most commonly in the extremities, and the majority of patients are young adults. This case report demonstrates an unusual site of occurrence for clear cell sarcoma.
