Multicentric reticulohistiocytosis. The long course of a rare disease.

ABSTRACT

Multicentric reticulohistiocytosis is a rare systemic disease. The patients usually develop an erosive polyarthritis in a few years. The most effective treatment is still unclear due to the few reports published of this disease. We report a case of multicentric reticulohistiocytosis with clinical, histopathologic and immunohistochemical study. The patient was treated with cyclophosphamide and nonsteroidal antiinflammatory drugs with an infrequent long-term survival.
