ABSTRACT

Histiocytosis is the name of a group of diseases affecting skin and visceral organs with a pathogenesis not fully understood. Histiocytosisis classified in two groups based on pathological examination: Langerhans cell histiocytosis(LHC) and non-LCH. Benign cephalic histiocytosis(BCH) belongs to non-LCH group and it is a rare skin disorder characterized by yellow, red-to-brown multiple small papules occurred on scalp, face, neck and superior part of body. Histopathological examination of BCH shows histiocytes at superior and mid dermis without any epidermotropism. Our case was a girl at 5 months of age and yellow-red papules with a diameter of 0,3-0,6 were present on the face and auricle, predominantly on the scalp. BCH diagnosis was made by clinical and histopathological examination
