What is it?

Bullous is a rare skin condition that causes large, fluid-filled blisters. They develop on areas of skin that often flex- such as the lower abdomen, upper thighs, or armpits. Bullous is most common in older adults. Bullous occurs when the immune system attacks a thin layer of tissue below the outer layer of skin. This abnormal immune response is unknown, although certain medications can sometimes trigger it.

Bullous Dermatosis.

Signs & symptoms

Signs and symptoms of bullous may include:
- Itching skin, weeks or months before blisters form
- Large blisters that don't easily rupture when touched, often along creases or folds in the skin
- Skin around the blisters that is normal, reddish, or darker than normal
- Eczema or a hive-like rash
- Small blisters or sores in the mouth or other mucous membranes


Diagnosis of a bolus is made through a skin biopsy and laboratory testing.


Treatment is focused on healing the skin and relieving itching while minimizing the adverse side effects of medications. Corticosteroids are the most common treatment.
