Abstract

A 6.7 kg 7 year-old castrated male domestic short hair cat was presented with several dermatological lesions on the ventral abdomen. The skin of the abdomen and inner thighs was affected. Both inner thighs were equally involved. They were covered with thick and folded, “card-board” devitalised skin. Some ulcerative haemorrhagic lesions were coated by greyish pseudomembranes of necrotic epithelium and fibrin. There was a distinctive margin between normal and affected skin. On the abdomen there was patchy erythema and papules. No other skin lesions were found on the rest of the body. Differential diagnoses for the lesions included: drug reaction, erythema multiforme, toxic epidermal necrolysis, vasculitis, and impetigo. Histopathology revealed different lesions: superficial pustules, ulceration and fibrin exudation, pustule disease with hair follicle destruction. There was no evidence of bacteria on cytology and histopathology. All previously prescribed drugs were stopped. On the day after initial proceeding lesions become less haemorrhagic and less thick. On the fourth day skin lesions were dry. Local therapy (povidone iodine) was maintained and the cat was sent home on day 5. Conclusion of case is sterile neutrophilic dermatitis.
