Plain-English summary
A 30-year-old mixed-breed mare was experiencing chronic weight loss and intermittent abdominal pain. Despite normal blood tests, a mass was found in her abdomen during a rectal exam. Unfortunately, her discomfort continued, and she was euthanized. A necropsy revealed a large tumor in her colon and smaller tumors in her liver, confirming a diagnosis of colonic adenocarcinoma with osseous metaplasia (a type of cancer).

Abstract
Rectal palpation of a 30-year-old mixed-breed mare with chronic weight loss and intermittent, refractory abdominal pain revealed a mass in the right caudoventral portion of the abdomen. Hematologic and serum biochemical findings were normal except for slight mature neutrophilia and mildly high alkaline phosphatase activity and total bilirubin concentration. Cytologic examination of a specimen obtained by abdominocentesis revealed equal numbers of nondegenerative neutrophils and macrophages, but no evidence of neoplastic cells. The mare continued to have signs of abdominal discomfort and was euthanatized. Necropsy revealed a large mass at the junction of the right dorsal colon and transverse colon, and several smaller masses in the liver. Histologic characteristics of the small-colon mass were consistent with colonic adenocarcinoma with osseous metaplasia.
