We reviewed fifteen cases of primary bone tumor which involved the periacetabular region. Histologically confirmed diagnosis of the tumors included four osteosarcomas. four chondroblastomas. three eosinophilic granulomas, two aneurysmal bone cysts and two osteochondromas. The tumors could be characterized by their sites of involvement: the majority of benign lesions occurred at the superior or superomedial aspect of the acetabulum and grow out mainly toward the body of ilium, while the malignant tumors generally involved the ischiopubic region and extended to the anteromedial or inferior acetabulum. The results of treatment for the benign lesions were satisfactory after intralesional curettage or marginal resection. but for the malignant tumors the diagnosis were frequently delayed and their prognosis were poor.
