Stress fractures: diagnostic pitfalls in juvenile idiopathic arthritis.

In arthritis patients, diagnosis can be delayed further because symptoms of the underlying disease might mimic complaints caused by the fracture. In this report, we present two JIA patients with stress fractures. A 10-yr-old girl with polyarticular JIA and a 14-yr-old boy with systemic onset of JIA presented with complaints of pain, the boy in the left extremity and the girl in both lower extremities, at a regular followup visit in our pediatric rheumatology clinic.
