Abstract:
Histiocytic ulcerative colitis (HUC) is described in three non-boxer dogs. Clinical signs were typical of large-bowel diarrhea and included soft stool, hematochezia, tenesmus, and an increased frequency of defecation. Diagnosis in each case was made by light microscopic evaluation of endoscopically obtained colonic biopsy specimens. Treatment regimes varied, but included immunosuppressive agents, anti-inflammatory drugs, antimicrobials, and dietary modification. Clinical response was substantial in two patients, while the third patient was euthanized due to treatment failure. The authors' observations indicate that HUC may be encountered in non-boxer dogs.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
