Pemphigus foliaceus skin eruption on the abdomen of a dog.

PF in animals produces clusters of small vesicles that quickly evolve into pustules. Pustules may rupture, forming erosions or become ...
These out ruled conditions can be for example; otoacariasis, atopic dermatitis, pemphigus, food hypersensitivity, autoimmune diseases and systemic lupus erythematosus. [13] Otoacariasis is a rare infestation of the ear canal, which can be caused by different types of mites and ticks.
For other regions, Tzanck test is mainly used to diagnose pemphigus and herpetic infections. Some clinics use biopsies even for herpetic infections. [4] This is because the advantages of this test are not well known, and the main textbooks of dermatopathology do not include dedicated sections for cytology or Tzanck smear. [5]

It occurs in humans [1] and cats, more frequently occurring in dogs. It was first described in dogs by Griffin and colleagues in 1979. [2] [3] DLE is one form of cutaneous lupus erythematosus (CLE).

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. [2] Mucosal involvement is absent even with widespread disease. [3]
Acantholysis is the loss of intercellular connections, such as desmosomes, resulting in loss of cohesion between keratinocytes, [1] seen in diseases such as pemphigus vulgaris. [2] It is absent in bullous pemphigoid , making it useful for differential diagnosis .
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.
