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 a group of autoimmune blistering diseases that may be classified into these types: [14] Pemphigus vulgaris; Pemphigus vegetans; Pemphigus vegetans of Hallopeau; Pemphigus vegetans of Neumann; Pemphigus foliaceus, of which there several forms: Pemphigus erythematosus or Senear–Usher Syndrome
Treatment includes irrigation and debridement of necrotic areas (areas of dead and/or dying gum tissue), oral hygiene instruction and the uses of mouth rinses and pain medication. If there is systemic involvement, then oral antibiotics may be given, such as metronidazole . [ 3 ]
A 2010 (updated in 2023) meta-analysis of 14 randomized controlled trials showed that oral steroids and potent topical steroids are effective treatments, although their use may be limited by side-effects, while lower doses of topical steroids are safe and effective for treatment of moderate bullous pemphigoid.
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.
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 ...
In more severe treatment it is treated similarly to pemphigus vulgaris. Pemphigus foliaceus is an autoimmune blistering disease of the skin. [ 1 ] Pemphigus foliaceus causes a characteristic inflammatory attack at the subcorneal layer of epidermis , which results in skin lesions that are scaly or crusted erosions with an erythematous (red) base ...
Oral mucosa is the most common site being affected in mucous membrane pemphigoid. For the mild oral mucosa lesion, high potency topical steroids such as 0.05% Clobetasol propionate is used. Patients are instructed to apply the ointment or gel 2-3 times a day after drying the oral mucosa to enhance the adherence of mediation to oral mucosa.
