Pênfigo foliáceo em felino: relato de caso

Abstract

Dermatopathies are within the most frequent affections in the veterinary clinical routine. Amongst them, autoimmune dermatoses are considered rare, caused by disorders of the patient's own immune system. Pemphigus foliaceus is the most common form of the pemphigus complex in domestic cats, as well as the most common autoimmune dermatopathy in this species. Like other affected species, the animals develop pustules that break easily, forming crusts. The disease affects the regions of the face, ears, and feet, but it can also affect the trunk and limbs, usually in a symmetrical way. Diagnosis is based on medical history and anamnesis, physical examination, clinical signs, cytology, histopathology, and immunohistochemistry. The aim of this paper is to report a case of pemphigus foliaceus in a feline, making a literature review on the subject. The patient was seen in March 2021 with an extensive previous medical history. The main complaints were scaling, alopecia and generalized crusting; bilateral otitis, with many crusts and discharge; paronychia in multiple digits; with an evolution of approximately three months. After performing the complementary exams that allowed the determination of the diagnosis of pemphigus foliaceus, the patient responded satisfactorily to corticosteroid therapy.
