If you see tense blisters on your arms and legs, chances are there that you’ve contracted bullous pemphigoid.
Bullous Pemphigoid is a type of chronic skin disorder associated with the outbreak of tense blisters on the skin surface. The blisters are large and fluid-filled that usually appears on the areas that often flex, such as arms, armpits, lower abdomen and legs.
While the exact causes of bullous pemphigoid are not well-understood, it is believed these blisters occur because of a malfunction in your immune system. Human immune system releases antibodies to fight foreign bodies like bacteria, viruses, etc. For reasons that are not clear, the body may develop an antibody to a particular tissue in your body.
When these antibodies connect the epidermis and the next layer of skin (dermis), these trigger inflammations which produces the blisters and itching of bullous pemphigoid.
What are the Types?
This skin disorder may be present with various clinical presentations, as follows:
- Generalized – Most common form in which the tense bullae arise on any part of the skin surface
- Vesicular -Manifests as groups of small and tense blisters, usually on an urticarial or erythematous base.
- Vegetative form – A very rare form with vegetating signs in intertriginous areas of the skin, including the neck, axillae, groin, and inframammary areas.
- Generalized erythroderma - This form resembles psoriasis, atopic dermatitis, or other skin conditions having the characteristics of an exfoliative erythroderma.
- Nodular - This rare type has clinical features that resemble prurigo nodularis, with blisters arising on normal-appearing skin.
The primary feature of this chronic skin disorder is the appearance of large, tense blisters that don't easily break when touched. Usually the fluid inside the blisters is clear; however it may contain some blood. Some affectants may develop eczema or hive-like rash rather than blisters. The skin around the blisters may look normal, reddish or darker than usual.
This disorder causes itching on the affected areas of skin. Blisters are also sometimes developed in the mouth. If you develop blisters on your eyes, scarring can be common. This condition requires prompt diagnosis and treatment.
