An 8-year-old cat was presented with pruritus, purulent paronychia, scaling, crusting, and spontaneous alopecia. Histopathology revealed intraepidermal neutrophilic pustular acantholytic dermatitis and hyperkeratotic cytotoxic interface dermatitis. No thoracic mass was seen on a lateral radiograph. Ectopic thymoma was discovered on necropsy. This case highlights the necessity for thorough investigation of any case of feline exfoliative dermatitis and pemphigus foliaceus for the presence of thymoma. Key clinical message: Comorbidity of exfoliative dermatitis and pemphigus foliaceus in a cat should prompt a thorough investigation for presence of a thymoma, possibly with advanced imaging techniques.
一只 8 岁的猫出现瘙痒、脓性甲周炎、鳞屑、结痂和自发性脱毛。组织病理学显示表皮内中性粒细胞脓疱性棘层松解性皮炎和角化过度细胞毒性界面性皮炎。侧位 X 光片未见胸腔肿块。尸检发现异位胸腺瘤。本病例强调了在任何猫的表皮松解性皮炎和落叶性天疱疮病例中，都需要彻底调查胸腺瘤的存在。关键临床信息：猫的表皮松解性皮炎和落叶性天疱疮合并存在时，应彻底调查胸腺瘤的存在，可能需要使用先进的成像技术。
