Chondroblastoma is a benign bone tumor accounting for less than 1% of bone tumor. It infrequently involves the flat bones, among which ribs are particularly rare. On fine needle aspiration cytology, the diagnostic smear consists of chondroblasts, osteoclast-like giant cells, and chondroid matrix. The cytologic hallmark to differentiate from other giant cell-containing lesions is chondroblasts.
