Polyostotic Paget disease involving bones of the upper extremity

Paget disease of bone (PD) is a common skeletal disease. It is usually polyostotic and most frequently involves the pelvis, femur, spine, skull, and tibia. The bones of the upper extremity in poly- or monostotic PD are rarely affected. A patient with PD involving the third left metacarpal bone and carpal bones of the right hand is described.
