A large fibrotic mass originating from the cecal base was discovered upon surgical exploration of the abdomen in a Thoroughbred mare with a history of chronic colic and weight loss. The mass protruded intraluminally resulting in partial obstruction. Surgical excision was not feasible due to the location of the mass and the inability to exteriorize it adequately from the abdominal cavity. The mass was fibrous with a shiny, gelatinous material present throughout the neoplasm. Histologically, large confluent spaces filled with mucopolysaccharides were identified by staining with Alcian blue. The diagnosis of myxosarcoma was based upon finding of atypical fibroblastic cells, mucinous stroma, local invasiveness, and metastasis to the regional lymph nodes. Myxomatous tumors have not previously been documented to occur in the equine intestinal tract.
在一匹患有慢性绞痛和体重减轻病史的纯种母马进行腹部手术探查时，发现一个起源于盲肠基部的巨大纤维化肿块。该肿块向腔内突出，导致部分梗阻。由于肿块的位置以及无法将其充分从腹腔中取出，手术切除不可行。肿块为纤维性，整个肿瘤内都有闪亮的凝胶状物质。组织学上，通过阿尔辛蓝染色鉴定出充满粘多糖的大融合空间。黏液肉瘤的诊断基于发现非典型成纤维细胞、黏液性基质、局部侵袭以及区域淋巴结转移。此前尚未有黏液瘤性肿瘤在马肠道中发生的记录。
