A Subcutaneous Juvenile Xanthogranuloma in a 4-Year-Old Girl Who Presented with a Lower Eyelid Mass.

Juvenile xanthogranuloma (JXG) is a relatively uncommon, benign, histiocytic proliferative cutaneous disorder that typically affects children, with the head and neck being the most common sites. The present case report describes an isolated subcutaneous JXG in a 4-year-old girl who presented with a circumscribed oval mass located in the lower eyelid of the right eye. This lesion was histologically diagnosed as JXG after a surgical resection of the mass.
