The medical records of 34 dogs (median age, eight years) with colorectal mucosal lesions were reviewed. Hematochezia was the most common (82%) presenting sign. Most dogs (79%) presented with solitary masses located in the rectum. After histological review, 12 masses were classified as adenomatous polyps and 22 as carcinoma in situ. Recurrence of clinical signs were common (41%), and malignant transformation of the tumor was documented in 18% of the cases. A higher recurrence rate and malignant transformation occurred in dogs presented with multiple masses or diffuse disease and in dogs initially diagnosed with carcinoma in situ.
回顾了34只患有大肠黏膜病变的犬（中位年龄8岁）的病历。便血是最常见的（82%）临床表现。大多数犬（79%）表现为直肠内的孤立性肿块。经组织学检查，12个肿块被分类为腺瘤性息肉，22个为原位癌。临床症状复发很常见（41%），18%的病例记录有肿瘤恶变。出现多个肿块或弥漫性疾病的犬以及最初诊断为原位癌的犬复发率和恶变率更高。
