Not All Scabs Are Just a Simple Skin Problem
What appeared to be a persistent skin condition was diagnosed as pemphigus foliaceus—an autoimmune skin disease in which the immune system mistakenly attacks the structures that normally hold skin cells together.
This loss of cell-to-cell adhesion can result in fragile pustules that rupture quickly and develop into crusts, scales, erosions, and non-healing sores. Lesions commonly affect the face, nose, ears, paw pads, and other areas of the body. Some dogs may also experience itching, discomfort, fever, reduced appetite, or decreased activity when the disease is widespread.
Because pemphigus foliaceus can resemble bacterial infections, fungal disease, parasitic conditions, allergies, and other dermatologic disorders, proper diagnostic evaluation is important. In this case, skin cytology helped assess the lesions and guide treatment, together with the patient’s clinical presentation and response to therapy.
Management focused on:
• Controlling the abnormal immune response
• Treating or preventing secondary skin infection
• Reducing inflammation, itching, and discomfort
• Monitoring the healing of crusts and open lesions
• Adjusting treatment according to the patient’s clinical response
• Providing regular follow-up for long-term disease control
Treatment of pemphigus foliaceus is rarely immediate. Many patients require prolonged therapy, gradual medication adjustments, and continued monitoring because the condition may relapse even after the skin improves.
With consistent veterinary care and strong commitment from the family, this patient’s wounds healed, itching improved, and the coat and skin condition recovered significantly. The dog is now bright, alert, responsive, comfortable, and well-groomed.
Persistent crusting, recurring scabs, hair loss, or sores that do not heal should not be dismissed as a simple skin problem. Visit AVCI for a proper dermatologic assessment.
