A Cat Histologically Showed Inflammation at the Sebaceous Gland

Abstract

A 10-year-old, spayed female, mixed cat was presented with alopecia and scaling on the head and neck for a half-year. Skin scraping and fungal culture did not show any abnormality, and administration of ivermectin and itraconazole were not effective. Histopathologic examination revealed granulomatous inflammation at the sebaceous gland, and mural folliculitis associated with CD3 positive T cells were observed. The cat was treated with prednisolone 2 mg/kg SID, and hair growth appeared afterward.
