title: Case for diagnosis. Benign cephalic histiocytosis.
abstract: The present paper reports a case of benign cephalic histiocytosis in a 15-month baby boy, who developed multiple papules bilaterally in the malar region with no other associated manifestations. Histopathology revealed a papillary dermal pattern, while immunohistochemistry was negative for S100 and CD1a and positive for CD68. Therefore, diagnosis was established as non-Langerhans cell histiocytosis, based on the clinical, histopathological and immunohistochemical features present.
