Immune Dysregulation, Polyendocrinopathy, Enteropathy, X-Linked Syndrome Manifesting as Lymphocytic Interstitial Pneumonia and Treatment-Resistant Bullous Pemphigoid.
Abstract
Immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX) syndrome is a rare immune deficiency with a broad clinical presentation. IPEX syndrome causes dysfunctional regulatory T cells, increasing the risk of autoimmune diseases. In this case report, we describe a 7-year-old boy with lymphocytic interstitial pneumonia and bullous pemphigoid who was recently diagnosed with IPEX syndrome.
