A rare case of chondromyxoid fibroma of distal phalanx of great toe

Abstract

Chondromyxoid fibroma (CMF) is rare benign tumour of bone which are due to incomplete cartilage differentiation and first described by Jaffe and Lichtensein in 1948. CMF’s constitutes for less than 1% of all bone tumors. Histopathology is diagnostic and CMF show lobulated areas of spindle shaped or stellate cells with hypocellular center of chondroid or myxoid material and periphery is hypercellular with abundant fibromyxoid tissue and few multinucleated osteoclasts like giant cell. CMFs are commonly seen in metaphysis of long bones including proximal tibia or distal femur. Short tubular bones of hand and feet are uncommon sites and toes constitutes less than 5% of the tumors. We present a case of chondromyxoid fibroma of distal phalanx of left great toe in 35 years old male patient.
