OBJECTIVE: To evaluate the usefulness of an intra-operative tissue imprint as a role to provide a provisional diagnosis in patients with musculoskeletal tumors. MATERIAL AND METHOD: 118 patients underwent surgical treatment for musculoskeletal tumors. Tissue imprints from suspected tissues were conducted in all of the patients and the results were compared with the final permanent section. RESULTS: The usefulness of the imprint slides (i.e., the diagnostic yield) was 88.14%. The respective, overall sensitivity, specificity, accuracy, positive and negative predictive value was 93.75%, 100%, 96.15%, 100% and 90.90%. CONCLUSION: Tissue imprinting is a useful method for intra-operative evaluation of adequacy and provides a provisional diagnosis of the musculoskeletal tumors lesions.
