The detection of an abdominal mass represents a common finding in clinical practice. The aim of this study was to retrospectively describe the tissue distribution and diagnosis of abdominal masses amenable to surgical removal in a canine population. Dogs with abdominal masses with a minimum diameter of 3 cm were selected. Cases were classified, based on the anatomical location, as splenic, gastrointestinal, hepatobiliary, genital, and masses not associated with any organ. Masses were surgically removed and formalin-fixed for the histological examination. Collected data were statistically analyzed. A total of 123 masses were collected from 122 dogs. Sixty-nine masses were classified as malignant neoplasia, 15 as benign, and 39 as non-neoplastic. The abdominal masses were 5.8-fold more likely to be malignant if located in the gastrointestinal tract ( = 0.01). A significant association between the size and the site of the masses was identified, the masses not associated with any organ being larger than the genital and splenic lesions ( = 0.008). This case series describes the most frequent location in association with the histopathological diagnosis of canine abdominal masses and suggests that the gastrointestinal location was related to a higher risk of representing a malignant neoplasm.
腹部肿块的检测是临床实践中的常见发现。本研究的目的是回顾性描述犬类群体中适合手术切除的腹部肿块的组织分布和诊断情况。选择最小直径为3 cm的腹部肿块犬。根据解剖位置，病例分为脾脏、胃肠道、肝胆、生殖器官以及与任何器官均无关的肿块。肿块通过手术切除并经福尔马林固定用于组织学检查。对收集的数据进行统计分析。共从122只犬身上收集了123个肿块。69个肿块被分类为恶性肿瘤，15个为良性，39个为非肿瘤性。如果位于胃肠道，腹部肿块为恶性的可能性要高5.8倍（P = 0.01）。确定了肿块大小与部位之间存在显著关联，与任何器官均无关的肿块大于生殖器官和脾脏病变（P = 0.008）。本病例系列描述了犬腹部肿块组织病理学诊断最常见的部位，并表明胃肠道部位与代表恶性肿瘤的较高风险相关。
