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.
