To describe the treatment of subcutaneous lipomas in the horse.
3 horses.
The horses were aged 1 to 2 years old, with lipoma of the abdomen, prepuce, and tarsus.
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.
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.
描述马的皮下脂肪瘤的治疗方法。
3 匹马。
这些马的年龄为 1 至 2 岁，患有腹部、包皮和跗关节的脂肪瘤。
所有病例均在全身麻醉下通过手术切除肿块。1 例侵袭性腹部脂肪瘤在被动引流管出口处复发，用顺铂注射治疗无效，再次采用主动引流管进行修正手术，成功治愈。2 例包膜完整的包皮外侧脂肪瘤完整切除，无复发。3 例跗关节脂肪瘤不完全切除，马蹄健全，无进一步生长。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，无恶性证据。
皮下脂肪瘤相对罕见，主要影响≤2 岁的马。它们是良性的，尽管由于侵犯局部结构或影响正常运动，它们的存在可能是有害的。由于浸润性肿瘤与正常组织融合，其边缘难以识别。如果存在死腔，不完全切除可能导致肿块复发。如果担心存在死腔，使用主动吸引引流管有益。
