A 46-year-old woman, who was not named, has a rare autoimmune disease that causes her sex organs to blister.

After being examined by several doctors, he was finally diagnosed with pemphigus vulgaris.
Launch Health, pemphigus is a collection of autoimmune disorders that cause blisters on the skin and mucous membranes (such as the eyes, nose, mouth and every part of the body that secretes mucus).
Pemphigus vulgaris is the most common case, affecting about four out of every million people in North America, recruiting Anthony Fernandez, MD, a dermatologist at the Cleveland Clinic.
Pemphigus vulgaris specifically causes blisters which usually start from the mouth and then can move to the skin and genitals.
The doctor noted that the patient examined had blisters in the mouth when he arrived at the emergency room.
Blisters caused by pemphigus vulgaris are painful and not itchy, but they can make chewing and swallowing very difficult, according to the National Organization for Rare Disorders (NORD) report.
This disorder initially causes soft blisters, which can appear on healthy or irritated skin, the NIH added.

The good news is that patients with this disease can usually resume normal lives after they have been diagnosed and treated properly.
