Medical Definition of Giant hairy nevus
1.
These large pigmented (often hairy) congenital nevi are important because of their increased risk (10 to 15%) of conversion into malignant melanoma.
A biopsy can confirm if cells have turned malignant. Any change in a pre-existing nevus should prompt a physician evaluation.
