title: Juvenile xanthogranuloma with hematologic changes in dizygotic twins: report of two newborn infants.
abstract: We describe the first reported instances of juvenile xanthogranuloma (JXG) in dizygotic twins. They had characteristic skin lesions and subcutaneous nodules as well as hepatomegaly, anemia, and thrombocytopenia. These extracutaneous symptoms improved in 5 months, coincident with the resolution of the skin lesions. Although most patients with JXG have only cutaneous symptoms, some show such dramatic extracutaneous manifestations that the possibility of malignant disease is occasionally the principle concern. It is therefore necessary to make a precise diagnosis based on specific immunohistochemical and ultrastructural findings, and to evaluate for other organ involvement, including hematologic abnormalities.
