[Erythrodermic sarcoidosis (a clinical, light and electron microscopy study)]

We report on a 50-year-old patient suffering from erythrodermic sarcoidosis accompanied by visible enlargement of the peripheric lymph nodes. Histologic examination revealed epithelioid granulomas in the skin, in a lymph node, and in a liver biopsy. Ultrastructurally, we found a focal presence of cells with Langerhans' granules sometimes in a spatial relation to lymphoid cells within the corial granulomas.
