OBJECTIVE: The aim of the present study was to determine the spectrum, frequency and demographics of bone tumors. MATERIAL AND METHOD: A retrospective study of the 1,001 bone tumor specimens from the files at the Pathology Department of the Chiang Mai University Hospital, Thailand from 2000 to 2004. RESULTS: From the study, 41 were non-neoplastic mass lesions, and 960 were neoplastic, with 856 (89%) as primary and 104 (11%) as metastatic tumors. In the primary tumor group, 654 (76%) cases were of hematologic origin, and 202 (24%) were non-hematologic. The most common benign bone tumors were giant cell tumor (n = 37), osteochondroma (n = 25), and chondroma (n = 15). The most common malignant bone tumors were lymphoma-leukemia (n = 583), metastatic malignancy (n = 104), plasma cell myeloma (n = 71), and osteosarcoma (n = 58). CONCLUSION: The present study showed a higher frequency of osteosarcoma (68%), lower frequencies of chondrosarcoma (12%) and Ewing sarcoma (4%) among primary non-hematologic malignant bone tumors when compared with similar studies based on Western patients. Whether these differences reflect differences in the ethnic population or in practice patterns remains to be determined
