AZULAY-ABULAFIA, Luna et al. Case for diagnosis. An. Bras. Dermatol. [online]. 2011, vol.86, n.6, pp.1222-1225. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962011000600031.
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.
