Abstract

Caplan’s syndrome, known as rheumatoid pneumoconiosis, was first described by Anthony Caplan in 1953, who identified a rare lung disorder found in coal mine workers with rheumatoid arthritis. Although Caplan’s syndrome was found in patients with a variety of pneumoconioses, it mostly affects individuals with long exposure to crystalline silica. We present a case of Caplan’s syndrome in a patient with advanced stage of rheumatoid arthritis and silicosis.
