Background: Cystic lesions of the bones refer to fluid-filled or air-filled cavities within the bone tissue. The present study was conducted to assess pathologic evaluation of cystic lesions of bones.

Materials and Methods: 94 cystic lesions of bones of both genders were selected. From a macroscopic perspective, the samples showed signs of bleeding and irregularities, with some places exhibiting bone-like firmness. Each sample was embedded in paraffin and fixed in 10% buffered formalin and the pathological assessment using standard hematoxylin- eosinstained slides, guided by radiological images and clinical data was performed.

Results: Out of 94 patients, males were 54 and females were 40. 45 lesions were in lower extremities. Pelvis was involved in 16, vertebrae in 4, femur in 8, tibia in 7, fibula in 11. Upper extremities were involved in 30 cases. Humerus in 14, radius in 10, ulna in 6 and others in 19 cases. Intraosseous lipoma in 4, ossifying fibroma in 3, concurrent lesions in 6, giant cell tumor in 3, reparative granuloma in 1 and fibrous dysplasia in 2 cases. The difference was significant (p< 0.05).

Conclusion: Maximum cystic lesions were seen in males. The most common lesion was seen in pelvis, fibula, humerus and radius. Other lesions were intraosseous lipoma, ossifying fibroma, concurrent lesions, and giant cell tumor.
