Many cases of intraosseous ganglia can be found in foreign literatures, but only one case has been reported by Kudo and Ogino (1970) in Japan. In addition to that case, we would like to report another case here.Case: A 40 years old laborer had intermittent pain in the right ankle for the last five years. Recently his pain has increased and has become progressively more intense. According to the examination there was tenderness on the right medial malleolus without swelling and redness. Physical examination showed a normal ankle joint.The radiograph revealed a cystic lesion with sclerosing zone in the right malleolus in the surrounding area.Operation: The periosteum and the cortical bone were normal. The cyst was removed moderately and easily, and the remaining fibrous wall and neighbouring bone were curetted, and the area packed with cancellous bone chips obtained from the iliac bone. The joint surface was not inspected.The cyst had a fibrous thick wall and contained a clear gelatinous fluid like a typical ganglion.Pathology: The outside wall of the cyst was composed of dense fibrous tissue, the inside wall being composed of a layer of flat cells. Parts of the inner surface of wall were myxomatous.Remarks: Our case is a quite typical case in intraosseous ganglia. There is no relation between the racial and geographical factors in this disease so that many cases are expected to be reported in Japan. We have tried to study literatures about etiology in this disease.
