A Case of Overlap Syndrome of Dermatomyositis and Sjogren's Syndrome associated with IgA Nephropathy / 대한류마티스학회지

ABSTRACT

An "overlap syndrome" is used to describe patients who have two or more well-defined connective tissue diseases such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), systemic sclerosis (SSc), and polymyositis. Their coexistence is defined clinically and often by specific serologic tests. We report a case of dermatomyositis associated with IgA nephropathy that had overlapping features of Sjogren's syndrome. This dermatomyositis and Sjogren's overlap is a rarely reported overlap syndrome worldwide.
