Three cases of primary osseous alveolar sarcoma are reported. The tumor was of two different types as shown on X-ray films. Osteolytic type: the lesions occurred in the flat and short tubular bones with areas of patchy osteolytic destruction. Mixed type: the lesions, located in the long tubular bones, appeared as irregular compact shadow in the bone marrow without periosteal reaction or soft-tissue swelling besides areas of patchy osteolytic destruction. The pathological diagnosis was made according to the following: (1) tumor cells aggregating to form solid nest-like or alveolar structures; (2) antidiastase PAS positive granules in the tumor cell cytoplasm; (3) specific crystals in the tumor cell cytoplasm.
报告了3例原发性骨肺泡肉瘤。如X线片所示，肿瘤有两种不同类型。溶骨型：病变发生于扁骨和短管状骨，有片状溶骨性破坏区。混合型：病变位于长管状骨，除片状溶骨性破坏区外，骨髓内表现为不规则致密影，无骨膜反应或软组织肿胀。病理诊断依据如下：（1）肿瘤细胞聚集形成实性巢状或肺泡状结构；（2）肿瘤细胞质内抗淀粉酶PAS阳性颗粒；（3）肿瘤细胞质内有特异性晶体。
