Plain-English summary
A Thoroughbred mare was found to have a large, fibrous tumor at the base of her cecum, which is part of her digestive system. She had been experiencing ongoing abdominal pain (colic) and had lost weight over time. During surgery, the doctors discovered that the tumor was causing a partial blockage, but they couldn't remove it because of its location and size. Tests showed that the tumor was made up of unusual cells and had spread to nearby lymph nodes. This type of tumor, called myxosarcoma, has not been seen before in horses' intestines.
Abstract
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.
