Cytodiagnosis of ChondromyxoidFibroma of the Metatarsal Head: A Case Report.

Chondromyxoid fibroma (CMF) is a rare benign cartilaginous tumor with a predilection for the bones of lower extremities and about one fourth of the tumors involve the foot. Radiologically, an eccentric lytic lesion with well-defined margins is seen in the metaphysis of the bone. We hereby, report an 18 yr old young male who presented to Orthopedic Outpatient Department, JN Medical College, Aligarh Muslim University, India diagnosed with giant cell tumor of the third metatarsal bone of right foot on radiography but on fine needle aspiration cytology (FNAC) the diagnosis of CMF was made. Preoperative diagnosis of this benign condition helped in doing minimum surgical intervention in the form of curettage along with bone grafting. Histopathology further confirmed the diagnosis of CMF. The case is being discussed to highlight the importance of FNAC to diagnose these uncommon benign bone lesions.
