Multicentric reticulohistiocytosis: a case report

Abstract

With the present case report we call attention to the clinical entity of multicentric reticulohistiocytosis (MR). Referring to earlier case reports on this rare condition we present the history, clinical and histopathological findings. We stress the importance of revealing possible underlying internal diseases, including malignancies, and also the importance of histological examination of synovium when synovectomies are carried out in patients with arthritis of unknown cause, as arthritis commonly precedes the mucocutaneous lesions by years.
