Bouchard's nodes

Bouchard's nodes
Specialty	Rheumatology

Bouchard's nodes are hard, bony outgrowths or gelatinous cysts on the proximal interphalangeal joints (the middle joints of fingers or toes). They are seen in osteoarthritis, where they are caused by the formation of calcific spurs of the articular (joint) cartilage.

Bouchard's nodes are comparable in presentation to Heberden's nodes, which are similar osteoarthritic growths on the distal interphalangeal joints, but are significantly less common.

Eponym

Bouchard's nodes are named after French pathologist Charles Jacques Bouchard (1837–1915).
