Oral Pathology
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.

PeriodonticsFibrous gingival hyperplasia, also known as gingival overgrowth, is characterized by an increase in the size of the gingival tissue due to an excessive accumulation of collagen and other extracellular matrix components. This condition can be caused by various factors, including certain medications (like anticonvulsants, calcium channel blockers, and immunosuppressants), hormonal changes, or chronic inflammation.
