What is subcorneal pustulosis?

Subcorneal pustulosis is a skin condition where non-infected, pus-filled pustules or blisters form on the skin, especially in areas where the skin rubs together. The cause is unclear but may be linked to other systemic conditions or certain medications. It is not contagious or inherited. Adult women are at higher risk, but children can develop this condition too.

Symptoms of subcorneal pustulosis

  • There is a net-like or circular rash on parts of my skin

  • Bumps containing pus

  • Skin redness or red bumpy rashes

  • Skin over the entire body is red

Questions your doctor may ask to check for subcorneal pustulosis

Your doctor may ask these questions to diagnose subcorneal pustulosis

  • Does your skin have a circular or target like pattern?

  • Do you have bumps on your skin with pus?

  • Do you have red skin or red spots on the skin?

  • Do you have skin redness over the whole body?

Treatment for subcorneal pustulosis

A medication called dapsone is often used to treat this condition, which usually resolves within a month of starting treatment. However, due to the risk of recurrence, doctors may recommend maintaining treatment at a lower dose. Other medications may be considered if dapsone does not work or cannot be taken.
