Organizing Pneumonia Complicated with Erythrodermic Psoriasis

Abstract

A 66-year-old man presented to our hospital complaining of acute dyspnea from several weeks before. He had a fiveyear history of psoriasis vulgaris treated with topical glucocorticoid and vitamin D. He interrupted the medications several months prior to his presentation. A physical examination showed fiery red skin covered in scales from his head to his toes (Picture 1A and C). Chest CT revealed multifocal ground glass opacifications and patchy consolidation with a predominantly subpleural and peribronchial distribution (Picture 1B and D). A transbronchial lung biopsy showed lymphocytic interstitial inflammation (Picture 2A and B) with Masson bodies and foamy cells (Picture 2C and D). Cultures of bronchoalveolar lavage fluid revealed no growth. He was taking no chronic medications and did not have any other new drug exposure. He had neither autoantibodies nor other symptoms suggesting the diagnosis of a connective tissue
