Plain-English summary
A 10-year-old male neutered Domestic Shorthair cat was brought to the vet because he was not eating well, losing weight, and had blood in his stool. An ultrasound showed a mass in his colon that was affecting nearby tissue. Tests confirmed that he had B-cell lymphoma, a type of cancer. This type of lymphoma can look similar to other conditions, so it's important for vets to do further testing to get an accurate diagnosis.

Abstract
A 10-year-old male neutered Domestic Shorthair cat was referred for chronic inappetence, weight loss, and hematochezia and an abdominal mass. Abdominal ultrasonography revealed a heterogeneously hypoechoic transmural colonic mass, which extended beyond the serosa and into the adjacent mesentery. Cytology and clonality assays of fine needle aspirates of the mass and mesenteric nodules yielded a diagnosis of B-cell lymphoma. Colonic lymphoma with mesenteric involvement can have a similar appearance to carcinomatosis, therefore a definitive diagnosis requires sampling and further testing of the mesenteric lesions.
