Localized scleroderma (LS) is a sclerotic skin disorder rarely reported in the veterinary literature. We herein report the first case of a linear LS-like skin lesion in a cat. A 1-year-old castrated male Himalayan cat was presented with a 1-month history of an alopecic, indurated, serpiginous, branched skin lesion on the dorsal cervical to scapular area. The cat had no history of trauma, although a topical spot-on endectocide had been applied near the lesion. Histopathological examination revealed a focal area of hyperplastic dermal collagen with the absence of pilosebaceous units. The cutaneous lesion remained unchanged during a 2-year follow-up period. Clinical and histopathological similarities of this skin lesion with those of the linear form of LS in humans were considered.
局限性硬皮病（LS）是一种硬化性皮肤病，在兽医文献中鲜有报道。我们在此报告首例猫出现类似线状LS的皮肤病变。一只1岁去势雄性喜马拉雅猫，其颈背至肩胛区域出现一个月的脱毛、硬结、匐行性、分支状皮肤病变。该猫无外伤史，尽管曾在病变附近使用过外用滴剂驱虫药。组织病理学检查显示真皮胶原局部增生区域，且无毛囊皮脂腺单位。在为期2年的随访期间，皮肤病变保持不变。考虑到该皮肤病变与人类线状硬皮病在临床和组织病理学上的相似性。
