[Multicentric reticulo-histiocytosis; review of recent literature (since 1969)]

The review of recent literature (since 1969) shows 35 cases of multicentric reticulo-histiocytosis. This entity was first described as a dermatological disease, then as a dermatoarthritis. It is in fact a systemic disease which can involve many organs but is sometimes monosymptomatic. Its fatal outcome is, sometimes, the result of a disseminated neoplasia or a lymphoma. Its clinical and microscopic features allow to distinguish it from solitary reticulo-histiocytoma, generalized eruptive histiocytoma, congenital reticulo-histiocytosis of Hashimoto and Pritzker and familial histiocytic dermato-arthritis of Zayid.
