A Case of Dermatomyositis Causing Cryptogenic Organizing Pneumonia.

Cryptogenic organizing pneumonia (COP), also known as idiopathic bronchiolitis obliterans organizing pneumonia (BOOP), is a rare inflammatory condition. It often presents as sequelae of existing chronic inflammatory diseases such as rheumatoid arthritis, systemic lupus erythematosus, and various connective tissue conditions. This case describes a 28-year-old African American female who presented with a complex clinical picture involving chronic inflammatory processes and the pulmonary system. The initial evaluation suggested pneumonia to be the underlying cause of respiratory symptoms; however, ultimately, a diagnosis of BOOP with dermatomyositis was made.
