We report a patient with a huge malignant schwannoma of the rectum, who had persistently refused surgery for 40 months. A 58-year-old woman presented to Nippon Medical School Hospital of Tama-nagayama for first the time in June, 1990, with a complaint of anal pain. Investigations revealed a submucosal tumor of the rectum, 4cm in diameter. Subsequently, the patient presented to the hospital several times complaining of anaI pain, because of the rapid disappearnace of the pain, however, the patient refused surgery. In October, 1993, the patient was again admitted to the Tama-nagayama Hospital complaining of recurrent severe anal pain, mass, fever, weight loss and inability to walk and sit. Pus wasdi scharged from a huge hip tumor, 15×15×10cm in size. Laboratory investigation revealed high IAP values of 736μg/ml (normal 500≥). Abdominoperineal excision of the rectum was performed. Microscopic examination revealed the tumor to be a malignant schwannoma. The postoperative course was uneventful and the patient discharged from the hospital. Investigations revealed growth of the tumor. Thet umor was thus calculated to be 14 months from 4cm to 5cm in size, and 26 months from 5cm to 10cmin size.
