Histiocytosis is a rare group of heterogeneous diseases with abnormal tissue proliferation of mononuclear cells, we report a case of an infant of five months of age with papulonodular asymptomatic eruption on the trunk and proximal portion of the limbs without obvious organ involvement, eruptive histiocytoma is confirmed by histopathological and immunohistochemical analysis. Generalized eruptive histiocytosis is an uncommon variant with benign and self-limited course that does not require any treatment, recommending a periodic medical visits for its ability to evolve to other forms of non-Langerhans cell histiocytosis as disseminated xanthoma or juvenile xantogranuloma.
