title: [A case report of primary malignant hemangiopericytoma of the chest wall].
abstract: We described a very rare case of malignant hemangiopericytoma of the chest wall, which was surgically resected. The patient, a 50-year-old woman, came to our hospital because of an abnormal shadow in the right chest wall of X-ray film without any symptom. The diagnosis of hemangiopericytoma was made with preoperative cytologic examination by means of transcutaneous aspiration biopsy. The tumor was a 47 x 36 x 25 mm, round and sessile mass originating from the 5th intercostal tissue without pulmonary adhesion, and the patient underwent en bloc resection of the tumor with the 16 x 12 mm sized chest wall including the 4th, 5th and 6th ribs. Pathological diagnosis was malignant hemangiopericytoma. Postoperative course was uneventful, and the patient is now doing well without local recurrence and distant metastasis for 11 months after the operation. We reviewed 8 cases of this tumor reported in the Japanese literatures.
