Papular xanthoma is a persistent normolipemic, nonconfluent, eruptive xanthomatosis located on the face, trunk and rnucous m,mbranes with no internal involvement, which exclusively occurs in adults. Histologically there is an infiltration of foamy histiocyte-like cells and a few Touton giant cells in the upper dermis and middermis without inflammatovy cells or a pure histiocytic component. Papular xanthomas in the childhood age group were recently described and characterized by their self-healing course, leaving, anetoderma-like scars. We report a case of papylar xanthoma in a 21-month-old infant with typical clinical, histopathologic and immunohistochemical findings. The positive immunohistochemical staining with factor XIIIa confirms that papular xanthorna is included in the group of dermal dendrocytic disorder.
