Pemphigus vulgaris is a rare chronic blistering skin disease and the most common form of pemphigus.Pemphigus was derived from the Greek word pemphix, meaning blister. [1] It is classified as a type II hypersensitivity reaction in which antibodies are formed against desmosomes, components of the skin that function to keep certain layers of skin bound to each other.
Pemphigus is further divided in two major subtypes: pemphigus vulgaris (PV) and pemphigus foliaceus (PF). However, several other disorders such as IgA pemphigus, IgE pemphigus, pemphigus herpetiformis, drug-induced pemphigus, Senear Usher syndrome, and endemic pemphigus foliaceus exist, and are recognized by a dermatologist from the appearance ...

If no lesions are present on examination it may be useful way of demonstrating reduced epithelial adhesion. In contrast, in Pemphigus, the epithelium tends to disintegrate rather than form a bulla. Nikolsky's sign is present in pemphigus and mucous membrane pemphigoid, but not in bullous pemphigoid.
Desquamative gingivitis is a descriptive clinical term, not a diagnosis. [1] Dermatologic conditions cause about 75% of cases of desquamative gingivitis, and over 95% of the dermatologic cases are accounted for by either oral lichen planus or cicatricial pemphigoid. [1]
Pemphigus vulgaris; Cytomegalovirus; Arnault Tzanck did the first cytological examinations in order to diagnose skin diseases. [3] To diagnose pemphigus, he identified acantholytic cells, and to diagnose of herpetic infections he identified multinucleated giant cells and acantholytic cells.
It is also associated with pemphigus vulgaris and pemphigus foliaceus. [6] [7] It is useful in differentiating between the diagnosis of pemphigus vulgaris or mucous membrane pemphigoid (where the sign is present) and bullous pemphigoid (where it is absent). The Nikolsky sign is dislodgement of intact superficial epidermis by a shearing force ...
