1. xanthogranuloma, juvenile Benign disorder of infants and children caused by proliferation of HISTIOCYTES, macrophages found in tissues. These histiocytes, usually lipid-laden non-Langerhans cells, form multiple yellow-red nodules most often in the skin, the eye, and sometimes in the viscera. Patients appear to have normal lipid metabolism and are classified as a normolipemic non-Langerhans cell histiocytosis.
