A Case of Giant Nonlipidized Juvenile Xanthogranuloma / 대한피부과학회지

Juvenile xanthogranuloma, which is the most common non-Langerhans cell histiocytosis of childhood, presents characteristic histopathologic features including abundant foamy macrophages and Touton giant cells. Generally, juvenile xanthogranuloma shows clinical features of less than 20 millimeters in size, butrarely, some lesions called giant juvenile xanthogranuloma exceed 20 millimeters. We report a case of a 5-month-old boy with solitary giant juvenile xanthogranuloma on his postauricular area with the histologic feature of nonlipidized form. The patient received simple excision. No evidence of local recurrence or systemic involvements have been observed during 4 months of follow up.
