Fibrocartilaginous dysplasia in distal femur: A rare histopathological finding

Fibrocartilaginous dysplasia (FCD) or massive cartilaginous differentiation in fibrous dysplasia are interchangeably used terms. It is a rare variant of fibrous dysplasia (FD) which is benign, lytic, and expansile bone lesion and causes progressive deformity in the bones and may lead to pathological fracture. Radiologically, FCD may confused with cartilaginous benign and malignant bone tumours. FCD usually shows calcification in imaging. Surgical curettage or corrective osteotomy and histopathological examination of these lesions is necessary to differentiate it from other cartilaginous tumours. Here we report case of fibrocartilaginous dysplasia of distal femur in a 4-year-old male child.
