Title: Clear cell chondrosarcoma proximal femur with secondary aneurysmal component – A rarity
Abstract: Clear cell chondrosarcoma is a rare benign tumor constituting to about 2–4% of all chondrosarcoma. It was first described by Unni et al. in 19761 Common sites of occurrence are epiphyseo metaphyseal regions of femur, proximal humerus and proximal tibia. This tumor clinico radiologically is frequently misdiagnosed as benign lesion such as giant cell tumor, aneurysmal bone cyst, chondroblastoma & osteoblastoma. Conservative surgeries like curettage will lead to local recurrences, excision of the lesion & reconstruction is the treatment of choice.
