Difference Between Psoriasis and Ringworm

Ringworm vs Psoriasis

Ringworm is a type of fungal infection that affects the skin and scalp. It most commonly occurs in children but can also affect adults. Ringworm is usually treated with topical creams or ointments. Psoriasis is a chronic skin disorder that causes red, scaly patches on the skin. It can be very itchy and difficult to treat. Psoriasis often requires long-term treatment with topical medications and phototherapy.

In size, ringworm patches are two to four inches in diameter, while psoriasis patches vary in size.

In Appearance, ringworm patches can appear as individuals or in groups. In comparison, psoriasis patches can join together.

Ringworm commonly appears in moist places like the armpits, foot, and groin. In comparison, psoriasis is most commonly found on the elbows, hands, feet, knees, and back of the neck.

Ringworm is usually seen 10 to 14 days after contact, while psoriasis is a chronic skin condition.

Ringworm is highly contagious and spreads quickly from person to person, while psoriasis is not infectious.

There could be a number of reasons why the red circle on your skin might not be itchy. A few things to consider include:

  • Petechiae, also known as blood spots, are small, reddish patches that appear when capillaries under the skin break. They seem flat to the touch and may resemble a rash. They can result from a number of things, including strains, sunburns, and traumas.
  • You may be experiencing an allergic reaction to a new product or ingredient that has been added to your skincare routine.

Half-moon Shaped Rash

A jock itch can cause a half-moon shaped rash. A reddish skin patch is often where the jock itch starts in the groin region. It frequently forms a half-moon shape and extends to the upper thigh.
