Chondromyxoid fibroma of the metatarsal bone: A diagnosis using fine needle aspiration biopsy

Radiograph of the right foot showed a well-circumscribed lytic lesion in the head of the first metatarsal bone [Figure 1]a. T1-weighted magnetic resonance imaging of the right foot revealed a lesion with low intensity in the first metatarsal.Stellate cells and spindle-shaped fibroblast-like cells were also seen [Figure 1]c. Occasional scattered binucleate cells and multinucleated giant cells were observed [Figure 1]d. Based on the cytological findings, a diagnosis of CMF was suggested.Histopathology of the curettage sample showed pseudolobules of myxoid and chondroid tissue separated by zones of fibrous tissue [Figure 1]e. Mitotic figures were not seen.[...]the histopathological diagnosis of CMF was confirmed.
