ABSTRACT

Relatamos um caso de histiocitose cefálica benigna em uma criança do sexo masculino, de um ano e três meses de idade que desenvolveu múltiplas pápulas na região malar bilateralmente, sem outros comemorativos associados. A histopatologia caracterizou-se pelo padrão derme papilar, com imuno-histoquímica negativa para S100 e CD1a, e positiva para CD68, ficando assim estabelecido o diagnóstico desta histiocitose não- Langerhans, baseado nos aspectos clínicos, histopatológicos e imuno-histoquímicos característicos.


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.
