Multicentric reticulohistiocytosis: A mimic of gout and rheumatoid arthritis

ABSTRACT

Multicentric reticulohistiocytosis is a rare cutaneous-articular disease that may mimic more common disorders such as rheumatoid arthritis or tophaceous gout. In one fourth of patients, it is a paraneoplastic process. This brief overview is aimed at physicians who care for patients with polyarthritis, to alert them to distinctive features that differentiate multicentric reticulohistiocytosis from the common arthritides.
