Juvenile xanthogranuloma is an idiopathic benign tumor of histiocytes.
Occurring in early childhood, lesions can be solitary or multiple.
The red-brown to yellow papules are most common on the face or upper trunk. Surface telangiectasia are often seen. Lesions may occur elsewhere, including the iris and internal organs.
- Lesions regress spontaneously after months or years, sometimes leaving shallow scars.
