Which of the following diseases of the skin is the most likely to exhibit fluid blisters on the skin and/or oral mucosa?
1) Pemphigus
2) Lichen planus
3) Keratosis follicularis
4) Erythema multiforme
Oral Pathology
Answer: 1
Pemphigus is an autoimmune blistering disease characterized by the formation of bullae (fluid-filled blisters) on the skin and mucous membranes, including the oral mucosa. This condition occurs when the body's immune system mistakenly attacks the proteins that bind the layers of the skin together, leading to separation and blistering. The blisters are usually large and painful, and they can rupture easily, leaving raw, exposed areas of skin or mucous membrane.
Lichen planus, keratosis follicularis, and erythema multiforme are other skin conditions but do not typically present with fluid blisters as the main feature.
