We treated a 79-year-old woman with hemangiopericytoma of the chest wa
ll. This is a very rare entity, with only a total of 12 cases includin
g our case reported in Japan. There is a predominance of women (10 fem
ale patients and two male patients) and a predilection for the right s
ide (9 in the right side and 3 in the left side). (C) 1997 by The Soci
