Abstract：
OBJECTIVE: To describe the treatment of subcutaneous lipomas in the horse.
METHODS: 3 horses.
METHODS: The horses were aged 1 to 2 years old, with lipoma of the abdomen, prepuce, and tarsus.
RESULTS: All cases had surgical removal of the masses under general anesthesia. Recurrence of an invasive abdominal lipoma occurred in case 1 at the exit site of a passive drain. The recurrence was treated unsuccessfully with injectable cisplatin, and a second revision surgery with the use of an active drain resulted in resolution. In case 2, complete resection of an encapsulated lipoma of the lateral prepuce was successful with no recurrence. In case 3, incomplete resection of a tarsal lipoma resulted in a sound horse, with no further growth. Histopathologic analysis revealed that all masses were composed of well-differentiated adipocytes with no evidence of malignancy.
CONCLUSIONS: Subcutaneous lipomas are relatively rare and affect horses primarily ≤ 2 years of age. They are benign, although their presence can be deleterious due to invasion of local structures or the impact on normal locomotion. The margins of invasive tumors are difficult to identify due to their integration with normal tissue. Incomplete removal may allow for mass recurrence. Active suctions drains are beneficial if dead space is a concern.

摘要：
目的：描述马皮下脂肪瘤的治疗方法。
方法：3匹马。
方法：马匹年龄为1至2岁，腹部脂肪瘤，包皮过长,还有tarsus.
结果：病例1在被动引流出口发生侵袭性胸部脂肪瘤复发。用注射用顺铂治疗复发失败，使用主动引流的第二次翻修手术导致了解决。在病例2中，包皮包皮包膜脂肪瘤的完全切除是成功的，没有复发。在病例3中，不完全切除骨脂肪瘤导致马健全，没有进一步的增长。组织病理学分析显示，所有肿块均由分化良好的脂肪细胞组成，没有恶性肿瘤的迹象。
结论：皮下脂肪瘤相对罕见，影响≤2岁的马。它们是良性的，尽管由于入侵局部结构或影响正常运动，它们的存在可能是有害的。侵袭性肿瘤由于其与正常组织的整合而难以识别边缘。不完全切除可能会导致肿块复发。如果要关注死角，则主动抽吸排水是有益的。.
