Fine needle aspiration cytology in two cases of chondromyxoid fibroma of bone and review of literature

We report the cytological features of two cases of chondromyxoid fibroma (CMF) confirmed by histopathology examination. First case was a 40‐year‐old male who presented with a foot swelling, and the second case was a 16‐year‐old male with a lesion at the angle of jaw. A fine needle aspiration cytology (FNAC) was performed in both the cases. In first case, a correct diagnosis of CMF could be offered on FNAC. In the second case, though the cytology diagnosis was a sarcoma considering the cytological, radiological and clinical features, the histopathological examination confirmed the same to be a CMF. The cases are being discussed to highlight the usefulness of FNAC to diagnose these uncommon benign bone lesions and the potential pitfalls in the cytological diagnosis of chondroid lesions. Diagn.
