What could a circular non-itchy skin-colored rash be on your back that looks like little raised pimples?

A circular, non-itchy, skin-colored rash on the back that looks like little raised pimples could be a number of different things. Some possible causes include:

* Ringworm: This is a fungal infection that causes a red, itchy rash that can appear anywhere on the body. Ringworm can be spread through contact with an infected person or animal, or through contact with contaminated objects.

* Pityriasis rosea: This is a common skin condition that causes a rash of small, scaly, pink or red patches. The rash usually starts on the trunk and then spreads to the neck, arms, and legs. Pityriasis rosea is not contagious and usually goes away on its own in a few weeks.

* Tinea versicolor: This is a fungal infection that causes a rash of small, white or brown spots. The rash usually appears on the back, chest, and shoulders, but it can also spread to other parts of the body. Tinea versicolor is not contagious and can usually be treated with antifungal medication.

* Eczema: This is a group of skin conditions that cause red, itchy, inflamed skin. Eczema can be caused by a number of things, including genetics, allergies, and environmental triggers.

* Psoriasis: This is a chronic skin condition that causes red, scaly patches of skin. Psoriasis can be caused by a number of things, including genetics, stress, and certain medications.

If you are concerned about a rash on your back, it is important to see a doctor to get a diagnosis and appropriate treatment.
