Polyostotic Paget's disease.

Paget's disease of bone is a common metabolic bone disease in most of the European countries. The disease has distinct geographical distribution being rare in Asia. We report Paget's disease in a 70 years old Pakistani male who presented with history of pain in right leg with difficulty in walking for the last 5 months. Plain X-ray raised suspicion of Paget's disease of bone. Technetium-99m MDP bone scan showed involvement of multiple bones. Bone biopsy confirmed the diagnosis. This case illustrates that Paget's disease of bone does exist in Pakistan.
