TLDR The cat's skin condition improved after stopping drugs and using iodine, confirming it was sterile neutrophilic dermatitis.
A 7-year-old castrated male domestic short hair cat weighing 6.7 kg was diagnosed with sterile neutrophilic dermatitis after presenting with dermatological lesions on the ventral abdomen and inner thighs. The affected areas exhibited thick, folded, devitalized skin with ulcerative hemorrhagic lesions covered by necrotic epithelium and fibrin. Differential diagnoses included drug reaction, erythema multiforme, and toxic epidermal necrolysis, among others. Histopathology showed superficial pustules, ulceration, and hair follicle destruction, but no bacterial presence. After discontinuing all previously prescribed drugs, the lesions improved significantly, becoming less hemorrhagic and dry by the fourth day. The cat was treated with local povidone iodine therapy and discharged on the fifth day.
