My husband has purple spots on his scrrottam it only started with a couple now more has started coming up and if you rub over them they fade for couple seconds and come back but has scratched some off and more comes back?

This is common: It sounds like your husband is one of those special guys with a gene to get angiokeratomas here. They're unrelated to Fabry's, where they occur on the trunk. Best wishes.

Visualdx: Hi, it’s hard to say without a picture but there is a great app that may be able to help you get a diagnosis without being seen in person by a dermatologist. The app is called VisualDX and is one of the best, if not the best out there. Many clinicians, including myself, use it. Just snap a photo and it gives you a list of possible diagnoses. Good luck!
