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 ...
Pemphigus foliaceus is the most common autoimmune skin disease in dogs, making up around one-third of all canine autoimmune disorders. [16] This disease usually affects areas of the ears and face. [9] Early symptoms are characterized by depigmentation of the nasal palate, dorsal cleft in the mouth, the ear, and the periocular area around the ...
Nikolsky's sign (gentle lateral pressure) on unaffected mucosa or skin raises a bulla. 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.
[2] [3] It is seen along with Nikolsky's sign, both used to assess the severity of some blistering diseases such as pemphigus vulgaris and severe bullous drug reactions. [ 4 ] This sign is named for the Danish physician Gustav Asboe-Hansen (1917–1989), who first described it in 1960.
SSSS is a clinical diagnosis. This is sometimes confirmed by isolation of S. aureus from blood, mucous membranes, or skin biopsy; however, these are often negative. Skin biopsy may show separation of the superficial layer of the epidermis (intraepidermal separation), differentiating SSSS from TEN, wherein the separation occurs at the dermo-epidermal junction (subepidermal separation).

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.
In 1896, he defended his doctoral thesis on pemphigus foliaceus, in which he described a dermatological condition involving a weakening relationship among the epidermal layers. The sloughing of skin associated with certain varieties of this condition is now referred to as Nikolsky's sign.
