Question

Which affects mucous membranes – pemphigus vulgaris or bullous phemphigoid?

1) Pemphigus vulgaris
2) Bullous phemphigoid

Answer 1

Pemphigus vulgaris affects mucous membranes, causing blisters and erosions on both the skin and mucous linings, while bullous pemphigoid primarily affects the skin and typically spares the mucous membranes.

Step-by-step explanation:

Pemphigus vulgaris affects mucous membranes and is a rare autoimmune disorder that leads to the formation of blisters and erosions on the skin and mucous membranes. In contrast, bullous pemphigoid is another autoimmune blistering disorder, but it typically spares the mucous membranes and affects primarily the skin. Pemphigus vulgaris involves a greater risk of serious complications due to the involvement of the mucous membranes inside the mouth, esophagus, and other areas, whereas bullous pemphigoid generally has a better prognosis.
