Acantholytic cells pemphigus foliaceus

Diagnosis generally requires a skin biopsy, which shows typical features of rounded-up separated keratinocytes (called acantholytic cells) within the blisters in the upper layers of the epidermis. Pemphigus foliaceus is confirmed by direct immunofluorescence staining of the skin sections to reveal antibodies Group of acantholytic conditions including 4 main forms: pemphigus vulgaris, pemphigus foliaceus, paraneoplastic pemphigus and a newly described IgA pemphigus Caused by IgG or IgA autoantibody against epidermal antigens (commonly desmoglein 1 and desmoglein 3 and pemphigus foliaceus (PF) lesional skin (1-4) show acantholysis in absence of apoptotic features (rounding up of the cell, retraction of pseudopods, pyknosis, karyorrhexis, plasma membrane blebbing, and engulfment by resident phagocytes). In all of the lesional biopsies, a widening of the intercellula

The pemphigus group of autoimmune bullous dermatoses is characterized by loss of adhesion of epidermal keratinocytes (acantholysis). As a result, there is intraepidermal blister formation. This follows the binding of autoantibodies to important adhesion proteins, particularly the desmoglein subfamily of the cadherin supergene family Figure 2 Electron microscopy of lesional pemphigus skin. Pemphigus vulgaris (PV) lesional skin (1, 2) and pemphigus foliaceus (PF) lesional skin (1-4) show acantholysis in absence of apoptotic features (rounding up of the cell, retraction of pseudopods, pyknosis, karyorrhexis, plasma membrane blebbing, and engulfment by resident phagocytes)

Differential diagnosis of pemphigus foliaceus Pemphigus vulgaris: In this related condition intraepidermal acantholysis is seen within the lower suprabasal epidermis, with matching direct immunofluorescence at this level Pemphigus foliaceus (PF) is the most common feline autoimmune skin disease. Pemphigus diseases result from the formation of antibodies against keratinocyte structures, and differ because each has a different target antigen and/or histopathologic feature The word pemphigus is used for the entire group of autoimmune blistering diseases in which intraepidermal separation occurs via acantholysis. Pemphigus foliaceus is a specific type of superficial pemphigus and is clinically distinct from deep pemphigus diseases. Another example of superficial pemphigus disease is pemphigus erythematosus

These keratinocytes have lost their intercellular connections deeper in the epidermis and are usually found in animals with immune-mediated disease, such as pemphigus. Occasionally, severe bacterial infections and dermatophytosis can cause these cells to develop acantholytic process. Pemphigus vegetans, like pemphigus vulgaris, has suprabasilar clefts containing acantholytic cells but is dis- tinguished by collections of eosinophils in a hyperplastic epidermis.

  6. Pemphigus is an autoimmune disease caused by antibodies directed against both desmoglein 1 and desmoglein 3 present in desmosomes. Loss of desmosomes results in loss of cohesion between keratinocytes in the epidermis, and a disruption of the barrier function served by intact skin
  7. Practice Essentials. Pemphigus vulgaris is an autoimmune, intraepithelial, blistering disease affecting the skin and mucous membranes. It is mediated by circulating autoantibodies directed against keratinocyte cell surfaces. A potentially life-threatening disease, it has a mortality rate of approximately 5-15%. [ 1
