How is a cellular dermatofibroma diagnosed?

To diagnose a cellular dermatofibroma, your healthcare provider starts by looking at the lesion. You may have a skin biopsy to confirm if it’s a dermatofibroma or another type of skin lesion.

In a skin biopsy, your healthcare provider removes a small tissue sample. They send your tissue sample to a lab. In the lab, a pathologist (a doctor who specializes in examining body tissues) views it under a microscope.
