Progressive nodular histiocytosis
Progressive nodular histiocytosis is a rare normolipemic non-Langerhans cell histiocytosis characterized by progressive growth of multiple to disseminated asymptomatic skin lesions that range in appearance from yellow plaques to coalescence-prone red-brown papules nodules and pedunculated tumors up to 5 cm in size located typically on the face trunk and extremities (and rarely on conjuctiva and mucous membranes). Characteristic microscopic findings include a storiform spindle cell infiltrate in the deep dermis with xanthomatized macrophages and some Touton cells in the upper dermis. It is usually not associated with systemic disease.
