Case Report: Leprosy Osteoarticular Alterations Mimicking Rheumatoid Arthritis.

Deformities of bones of the face and extremities are markers of leprosy (Hansen's disease) which contribute to stigma associated with this disease. Among these deformities are articular alterations that can mimic rheumatoid arthritis (RA). In this case, a 64-year-old man presented with a history of having been treated for lepromatous leprosy and erythema nodosum leprosum episodes, which evolved with joint alterations similar to those of RA.
