A Case with Juvenile Xanthogranuloma and Progressive Nodular Histiocytosis Overlap

Abstract

A patient with overlap between juvenile xanthogranuloma and progressive nodular histiocytosis is presented. He had progressive, superficial, small, yellow-reddish papules and large dermal nodules, consistent with progressive nodular histiocytosis. Histopathology showed distinctive features of juvenile xanthogranuloma. Our patient reinforces the view that progressive nodular histiocytosis is not a distinct clinical entity, but an evolutionary form of juvenile xanthogranuloma.
