Chondroblastoma is a rare benign appearing lesion arising in epiphysis of long bones in skeletally immature individuals. It is cartilage producing neoplasm constituting < 1% of all bone tumours. A 16 years old girl presented to orthopaedic OPD of tertiary care hospital with swelling of left great toe since past 3 years. The swelling was insidious in onset, gradually progresses to present size of 3.5x2.5x2 cm. Radiographic examination shows an osteolytic lesion and coarse trabeculation in the distal phalanx of great toe suggestive of benign bone tumour. Histopathological examination showed classical features of chondroblastoma. Post-operative follow up was uneventful and radiological examination was normal. Flat bones like pelvis, ribs, vertebrae and scapula and craniofacial bones are other uncommon locations. The tumour recurrence rate is increased when the tumour is having limited resection due to site of tumour. Turcotte et al reported highest recurrence rate of tumour in flat temporal bone with recurrence within 6 months to 8 years. Chondroblastoma, an uncommon primary bone tumour presenting at distal phalanx of great toe was extremely rare.
