Rashes
Medically reviewed by Mitchell J. Mandel, M.D., F.A.A.D., Board-Certified Dermatologist. Last reviewed .
Rashes are one of the most common reasons people see a dermatologist. They can come from allergies, irritation, infections, medicines, autoimmune conditions and many other causes. Many look alike, which is why a proper diagnosis matters.
Our providers examine the rash, ask about when it started and what might have triggered it, and may do a scraping, culture, patch test or biopsy to find the cause.

Rash Q&A
Should I use hydrocortisone cream?
It can help mild itchy rashes, but it can make some rashes, like fungal infections, worse. If a rash is not clearly improving, have it checked.
Will I need a biopsy?
Most rashes can be diagnosed with an exam. A biopsy is used when the cause is unclear or the rash is not responding to treatment.
