Abstract

A 12-year-old Belgian draft horse presented for a right eye third eyelid mass and red-tinged ocular discharge of 3 months' duration. The third eyelid was excised and submitted for histopathology. On histopathologic examination, the mass was composed of both hemangiosarcoma and squamous cell carcinoma. The horse developed thickened eyelids and hemorrhagic ocular discharge from the right eye approximately 16 months following surgery, and was euthanized. Necropsy and histopathology confirmed local recurrence and regional metastasis of the hemangiosarcoma. This was an unusual case because there were two distinct neoplastic processes composing the same mass that could not be differentiated grossly.

摘要

一匹12岁的比利时挽马因右眼第三眼睑肿物及持续3个月的眼分泌物带血前来就诊。第三眼睑被切除并送组织病理学检查。组织病理学检查显示，肿物由血管肉瘤和鳞状细胞癌组成。术后约16个月，这匹马右眼眼睑增厚并出现血性眼分泌物，随后实施了安乐死。尸检和组织病理学检查证实血管肉瘤出现局部复发和区域转移。这是一例不寻常的病例，因为同一个肿物由两种不同的肿瘤性病变组成，肉眼无法区分。
