Fibrosarcoma in a girl with celiac disease and IgA deficiency.

A case of abdominal wall fibrosarcoma in a 17-year-old girl with celiac disease and IgA deficiency is described. Celiac disease was putatively diagnosed with intestinal biopsy at the age of 15 years when she came for hospital investigations because of IgA deficiency and recurrent respiratory infections. The tumor occurred at the age of 17 years during the gluten challenge performed for final diagnosis of celiac disease. Surgical excision, irradiation, and chemotherapy were initially successful. After 7 months, however, the tumor recurred. Reoperation and a new course of irradiation therapy coinciding with the reinstitution of a gluten-free diet proved to be effective in tumor eradication. Nine years after the cessation of cancer treatment she is well and has two healthy children.
