Frequently Asked Questions

QWhat exactly is a giant pigmented hairy nevus?

Quite rare, actually. They occur in about 1 in every 20,000 births, making them a relatively uncommon condition. So, not everyone will see one in person during their lifetime.

QCan giant pigmented hairy nevi be removed?

Yes, they can be surgically removed, though it's not always straightforward. Due to their size, removing them often requires multiple surgeries and can be quite complex. Doctors usually recommend removal mainly if there's a risk of the nevus developing into melanoma, a type of skin cancer.

QAre there any risks associated with having a giant pigmented hairy nevus?

Indeed, there are. The most significant risk is the potential for the nevus to develop into melanoma. While not all nevi will become cancerous, the risk is higher with larger ones, making regular monitoring essential.
