Abstract

Langerhans cell histiocytosis (LCH) is a clonal proliferative lymphohistiocytic disorder with mainly CD-1a positive staining. It has a wide spectrum of unifocal or multifocal mono or multisystemic disease. Rare symptoms like diabetes insipidus, hearing loss or nail distrophy might also occur according to the involved sites. In here, two cases of LCH with atypical presentation are reported with review of the literature.
