Polyostotic fibrous dysplasia with secondary aneurysmal bone cyst in tibia

Abstract

Fibrous dysplasia is a benign tumor-like lesion of bone believed to be developmental in origin. Polyostotic fibrous dysplasia (FD) is a rare condition. Our case was further complicated by the presence of secondary aneurysmal bone cyst (ABC). This is the second reported case of polyostotic FD with secondary ABC.
