With the exception of lipoma, neoplasia of the gastrointestinal tract is rare in horses. Lymphosarcoma is the most common neoplasm of the hematopoietic system in horses. In horses with lymphosarcoma of the large colon, clinical signs may include intermittent signs of mild abdominal pain, weight loss, pyrexia, and pelvic flexure impaction caused by impingement of the colonic lumen by the mass. Peritoneal fluid analysis may be normal or have a high total protein concentration. If signs of metastasis are not evident, resection of the large colon affected by the mass may prolong survival.
除脂肪瘤外，胃肠道肿瘤在马中很少见。淋巴肉瘤是马造血系统最常见的肿瘤。患有大结肠淋巴肉瘤的马，临床症状可能包括间歇性轻度腹痛、体重减轻、发热，以及因肿物压迫肠腔导致盆腔弯曲处堵塞。腹腔液分析可能正常或总蛋白浓度较高。如果没有明显的转移迹象，切除受肿物影响的大结肠可能会延长生存期。
