title: Chondroblastoma in fine needle aspirates.
abstract: The cytologic features of smears of fine needle aspirates from four chondroblastomas were studied. In an ideal fine needle aspiration biopsy sample of chondroblastoma, all the diagnostic details can be found: chondroid matrix surrounding individual round to oval mononuclear cells, calcifications among cells and multinucleate osteoclasts. Chondroid matrix, which we believe to be the decisive feature, and calcifications are seen better in Giemsa-than in Papanicolaou-stained smears.
