A 31-Year-Old Man With Bilaterally Limited Mobility of Joints

A 31-year-old man experienced insidious onset of limited mobility of joints, including interphalangeal (hands), metacarpophalangeal, wrist, interphalangeal (feet), metatarsophalangeal, and ankle joints. He was diagnosed as having eosinophilic fasciitis (EF) based on clinical characteristics, laboratory findings, and biopsy. This video shows the limited mobility of his interphalangeal (hands) and wrist joints, and he was unable to fully clench his fists or squat. Bilaterally limited mobility of joints is a useful clue for the diagnosis of EF. Click the Related Article link for full details.
