title: Chondrosarcoma of calcanaeum in a 12-year-old male patient: a case report.
abstract: Chondrosarcoma is distinctly uncommon and tends to be located often in the extremities in young patients more than in its adult counterpart. Cartilaginous tumors involving the small bones of the hands and feet are benign tumors such as enchondromas, chondromyxoid fibroma (CMF), and chondroblastoma. Chondrosarcomas involving calcanaeum in young adults are largely covered in the literature as single case reports. A young 12-yr-male patient presented with complaints of pain and mild swelling in the ankle. Radiological examination revealed a dense irregular lesion in the calcanaeum. Fine-needle aspiration was performed and a possibility of chondrosarcoma was suspected, which later was confirmed on histopathological examination. The cytopathologist should be aware of the occurrence of malignant chondroid tumors in the younger age group at this rare site. Correlation to radiological findings is essential in these cases.
