What are noninfectious, common rashes localized to a
particular anatomical area?
Common, noninfectious rashes are listed below. Since these conditions are not caused by infectious organisms, it is reasonable to attempt to treat them with
over-the-counter 1% hydrocortisone cream for a week or so prior to seeking medical attention.
Seborrheic dermatitis: Seborrheic dermatitis is the single most common rash affecting adults. It produces a red, scaling eruption that characteristically affects the scalp, forehead, brows, cheeks, and external ears.

I have had Tinea Versicolor for the last 15 years, since I was 15 years old. It began as a small dime-sized patch on my chest and never spread any larger. It wasn't until I was 19 that it began to spread all over my neck, upper chest, and up my neck to my ears, into my hairline and even in my groin area. In the last two years, it has become worse. I used to use dandruff shampoo to treat it, but I am allergic to ingredients in the shampoo. Creams, tea tree oil and other herbal-based creams don't work. The only solution I have found is the direct, light application of organic apple cider vinegar twice a day to clean skin. It takes about one week to begin fading, though I find that care needs to be taken to make sure my skin does not get irritated by the vinegar. By the end of two weeks, the redness and flaking are gone. There are times when the patches get quite red and a bit itchy, and other times that they fade and take on a pearly appearance. I can't pin down what it is -- my diet, environmental factors, hormones, etc. -- that cause them to seem to get quite red at times. My mother tells me my father had the same spots. And though I understand that this condition is not contagious, my partner of five years has now begun developing the same condition alongside his eczema.
