Juvenile and Adult-type Xanthogranuloma



Juvenile and Adult-type Xanthogranuloma


Elizabeth A. Montgomery, MD










This is a typical appearance of a juvenile xanthogranuloma removed from the face of a small boy. The lesion is uniform and cellular and proliferates in the dermis with no grenz zone.






Many Touton giant cells image can be seen in this juvenile xanthogranuloma. The background cells are spindled to ovoid with eosinophilic cytoplasm, which shows only minimal lipid in this case.
