Dark skin discoloration of finger joints in juvenile arthritis.
We examined the frequency of a known but poorly described finding, darkened skin over the proximal interphalangeal joints in patients with polyarticular juvenile arthritis. Examining a consecutive group of patients we found that 77% showed this sign. It reflects the presence of or previous episodes of inflammation of these joints. The reason for this finding is unknown.
