Commonly described pulmonary manifestations of Sj\u00f6gren syndrome include airway disease, interstitial lung disease, pulmonary arterial hypertension, and lymphoproliferative disorders. However, diffuse alveolar hemorrhage as a sequela of Sj\u00f6gren syndrome has rarely been described in the adult literature and has never been described in a child. Here we report the case of an 11-year-old girl who presented with diffuse alveolar hemorrhage and was diagnosed with childhood-onset Sj\u00f6gren syndrome who otherwise lacked typical clinical features, such as sicca symptoms, at the time of presentation. She was successfully treated with corticosteroids and rituximab, with sustained pulmonary remission 1 year post diagnosis. Our case highlights the heterogenous presentation of Sj\u00f6gren syndrome in the pediatric population and the need for increased awareness among pediatric providers to recognize potential systemic manifestations of this disease to avoid delayed diagnosis.<\/jats:p>","DOI":"10.1542\/peds.2020-042127","type":"journal-article","created":{"date-parts":[[2021,7,28]],"date-time":"2021-07-28T08:25:37Z","timestamp":1627460737000},"source":"Crossref","is-referenced-by-count":11,"title":["Childhood-Onset
