Chondroblastoma is a rare benign cartilaginous tumor typically seen in long bones, especially femur, tibia and proximal humerus. Extracortical soft tissue invasion or metastasis is rarely seen. We report here a unique case of chondroblastoma of the fibula with extracortical soft tissue invasion. Differential diagnosis on cytology is discussed.
