Case Report - Chondrosarcoma in the forefoot

Chondrosarcoma is a tumour rarely seen in the foot. An 18-year-old male patient visited our clinic with the complaints of swelling and pain in his right foot. On plain radiographs, there were lytic areas in the fifth metatarsal and the fourth and fifth fingers of the right foot. Computerized tomography revealed that there were mass lesions in the fourth and fifth fingers′ phalanges, causing a wearing off irregularly limited to adjacent fat plans and hypodense calcifications the fifth metatarsus, occurring destruction in bone. An open biopsy was taken from the region of the lesion under local anaesthesia. Histopathological diagnosis was reported as low-grade chondrosarcoma. We applied ray amputation to the patient under general anaesthesia from the fourth finger disarticulation and the fifth metatarsus. In a 3-year follow-up, no local recurrence and metastasis were observed. The difference of our case from the ones reported in the literature is that the patient was young (18-year-old) and had a lesion involving two different compartments synchronously as localization.
