Original publication title: Polypoid adenomas secondary to inflammatory colorectal polyps in 2 miniature dachshunds.
Plain-English summary
Two miniature dachshunds, a 7-year-old male and an 8-year-old male, were brought to the vet for ongoing bloody stools and straining to defecate. The vet found polyps in their colons during a procedure called colonoscopy and removed them. Both dogs were treated with medication to suppress their immune systems, which helped their symptoms, but the polyps returned over time. After a follow-up, the vet performed another colonoscopy and found that the polyps had turned into adenomas, which are a type of tumor. Ongoing monitoring and repeat biopsies are recommended for these dogs to manage their condition effectively.

Abstract
Two miniature dachshunds, a 7-year-old neutered male and an 8-year-old male, presented with chronic hematochezia and tenesmus. A solitary pedunculated or multiple diffuse colorectal polyps were identified by colonoscopy and resected by polypectomy. Inflammatory colorectal polyps (ICRPs) were diagnosed according to histopathological findings. Both cases were treated with immunosuppressive therapy, and the clinical signs were resolved, although the colorectal polyps remained to some extent. Several months after the initial diagnosis, both cases presented with recurrence of hematochezia and enlargement of the polyps. A second colonoscopic polypectomy was performed, and adenoma was diagnosed histopathologically in both cases. ICRPs are a nonneoplastic disease, but their long-term prognosis is unknown. Careful follow-up seems to be important, and repetitive biopsy is recommended when growth of polyps is identified in miniature dachshunds with ICRPs.
