I had it in college. It truly was unexplainable. It mostly was on my body wherever my underwear did NOT go. To this day I don't have pigmentation in my skin where I had the patches, but that's OK, my freckles cover a lot, LOL
There are several articles on the internet and some with pictures. Does this sound like it could be it? If it is pityriasis rosea, it is not contagious and is self-limiting. And like it says, you never have it again.
Pityriasis Rosea
Pityriasis rosea (PR) usually starts out as a small pink patch on the back or the chest. This is called the herald patch. Many people mistake it for ringworm (Read about "Tinea: Ringworm, Jock Itch and Athletes Foot.") and will try to treat it as such. That does no good because it is not caused by a fungus. Eventually more patches show up all over the body. They are smaller than the original herald patch. They may be itchy. Some people also suffer from other symptoms such as tiredness and aches. The patches usually go away on their own in 6 to 8 weeks but are known occasionally to last much longer. Most treatment involves dealing with the symptoms such as the itchiness. Lukewarm baths instead of hot are often recommended as is avoiding strenuous exercise and getting overheated if you are itchy. Exercise in itself does not make the rash worse. Occasionally sun exposure or a tanning bed is suggested on a limited basis, although caution should be used because of the increased risk of skin cancer from sun damage. The exact cause is unknown but AAD suspects a virus. One of the reasons is that once people recover from PR they tend not to get it again.

pityriasis rosea would not be on arms
It only goes all over your trunk. I had it on front and back.
