Multicentric reticulohistiocytosis: an example of the value of skin biopsy in joint disease

Abstract

We describe a case of multicentric reticulohistiocytosis. It is a rare condition but one which causes significant morbidity to skin and joints. There is no consensus on treatment, but here we report a good response to infliximab. We also use the case to emphasise the value of skin biopsy in diagnosing rheumatological conditions.
