What is bullous pemphigoid?

Bullous pemphigoid (bull-us pem-fuh-goyd) is a rare skin condition that causes itchy, hive-like welts or fluid-filled blisters.

It may affect a small area of your body or it may be widespread. Blisters may occur anywhere, but often develop on flexural areas of your skin, such as under your armpits (axilla), around your groin or on your stomach (abdomen). In some cases, blisters also form on mucous membranes, including your mouth, tongue, throat, esophagus and/or eyes.
