Two Cases of Juvenile Xanthogranuloma / 대한피부과학회지

ABSTRACT

Two Cases of Juvenile XanthogranuIoma(JXG) are reported with review of literatures. JXG is a rare disease, and have not yet been reported in this country. Case I Two months oId healthy female infant has two firm, discrete, brownish yellow waxy nodules on the left postauricular region and the left forearm. The lesion had begun as erythematous pinhead sized papules, and have been enlarged rapidly to pea siez during last three weeks. Case II Three year old healthy male has firm, discrete, pinhead to pea sized scattered 16 papules and nodules on the trunk and right side of neck. Laboratory findmgs and X-ray studies were normal in both cases and there were no evidence of metabolie disorder or bony abnormality. Histopathologic studies show similar findings in both cases. In hematoxylin-eosin staining, epidermis shows parekeratosis and slight elongation of rete ridges with suprapapillary thinning with focal spongiosis and invasion of inflammatory cells. The entire dermis, from dermal papillae to sbcutis, is replaced by granulomatous lesion composed with histioeytes and a few giant cell reaction, in addition to histiocytic proliferation, considerable amount of eosinophils are infiltrated with some lymphocytes and plasma cells. The dermal collagen fibers are partly degenerated. In the upper most portion, some foamy histiocytes are also seen. In frozen section and Sudan III fat staining, the tissue shows rnild reactivities.
