Photoletter to the editor: Pigmented dermatofibrosarcoma protuberans in a 4-year-old girl and ultrasonographic findings.

Ultrasonography and color Doppler imaging are useful noninvasive tools for the diagnosis of skin tumors and may help distinguish DFSP from other vascular skin lesions in children.
