title: A rare case of juxtaarticular osteoid osteoma of the calcaneus initially misdiagnosed as juvenile chronic arthritis.
abstract: Juxtaarticular osteoid osteoma is frequently misdiagnosed because the symptoms may mimic arthritis, and radiographs may not be characteristic. A rare case of subtalar pain lasting 5 years in a female teenager is presented here. The initial diagnosis was monarticular juvenile chronic arthritis. Family history was misleading because her mother had rheumatoid arthritis (RA).
