I've had this rash for 5 years. Been to a doctor and did not know what it is.
The picture of the rash was not very clear. If a doctor does not know what a rash is the best thing to do is a small skin biopsy and have it read by a dermatopathologist. From what I could see this lesion appears to be a dermal infiltrate. The infiltrate could be immune cells, granulation tissue or other substance. The only way to truly tell exactly what the composition is - is to have a tissue biopsy by a dermatologist.
