ABSTRACT
Background: Identification of the etiology of acute limping in children is challenging. Both benign and life- threatening disorders can present with limp. However, among atraumatic conditions, benign conditions including toxic synovitis and post infectious arthritis are the most common causes of this dilemma. Case Presentation: During the recent COVID-19 pandemic in Kerman, South East of Iran; two pediatric patients referred to the Rheumatology clinic with new onset gait disturbance. One 8 years old boy and the other 6 years old girl who presented with hip joint pain and limping. Both of them had joint effusion jackknife of mild respiratory symptoms and fever. Altogether, precise history taking and accurate physical examination, alongside radiological investigations and positive laboratory results for coronavirus infection emphasized the diagnosis of post Coronavirus arthritis. They treated with rest and Non-Steroidal Anti-Inflammatory Drugs (NSAID) successfully, and fallowed at least for one month later.Conclusions: Here, we described the first report of post n-CoV-2 arthritis in the world in two Iranian pediatric patients, who presented with limp. Contrary to preliminary phantasms, this may indicate that the Corona virus has some rheumatogenic specifications.
