Plain-English summary

A cat with a skin problem was diagnosed with pemphigus foliaceus, an autoimmune condition that causes crusty sores mainly on the ears, head, and paws. To confirm the diagnosis, the veterinarian performed a biopsy of the affected areas. Treatment options have improved over time, and most cats respond well to medication, although they may need to stay on it for a long time to keep the symptoms under control. With the right treatment, many cats can manage this condition effectively.

Abstract

Feline pemphigus foliaceus is an uncommon skin disorder in cats but still the most common autoimmune skin disorder seen in this species. It is a crusting dermatosis involving the ears, head, paws, and ungual folds primarily. Although cytology is helpful in supporting a diagnosis, biopsy of pustules or crusts for histopathology is required for a definitive diagnosis. Therapy has evolved over the years as we have learned more about the different ways cats respond to drugs and as new drugs became available. Most cats will respond to proper therapy, although it may be needed long term for control.
