Diagnosis:

Rheumatoid arthritis

Discussion:

Among the many osseous abnormalities that may be seen in Rheumatoid Arthritis, the swan neck deformity is the culmination of multiple abnormalities in the hand. Specifically, the deformity arises from hyperextension of the proximal interphalangeal joint, while the distal interphalangeal joint is flexed.
