In August 2000, she underwent wide resection of malignant fibromatous histiocytoma of the right pelvis. In January 2001, magnetic resonance imaging revealed herniation of the intestine through the ilium deficit and abdominal hernia was diagnosed. In March 2001, she underwent cleisis operation for abdominal hernia. In June 2001, however, magnetic resonance imaging revealed recurrence of hernia. A torus, 15 cm × 18 cm in size, was observed on the right abdominal wall, and trendelenburg sign was positive. Plain radiography and computed tomography revealed diffuse bone defect.
