Is disseminated juvenile xanthogranulomatosis benign cephalic histiocytosis?

We describe an infant with a congenital form of non-Langerhans cell histiocytosis with clinical and pathologic features of both disseminated juvenile xanthogranulomatosis and benign cephalic histiocytosis. The findings in this case support the concept of these non-Langerhans cell histiocytoses forming part of a spectrum of disease rather than being separate pathologic entities.
