1例犬多发乳腺肿瘤的外科治疗及病理学诊断

Surgical treatment and pathological diagnosis of a case of canine multiple breast tumor

12岁雌性博美犬,一年前进行乳腺肿块切除,就诊前一个月发现乳房多发肿块,经术前检查初步诊断为乳腺肿瘤、子宫蓄脓。对患犬进行综合评估,采取双侧乳腺切除术,配合超声刀切除子宫、卵巢。术后进行抗感染治疗,并给予利多卡因恒速输注(CRI)镇痛。术后6个月回访,患犬伤口恢复良好,状态稳定。对切除的3个肿瘤均进行病理组织学检查,结果显示:该犬多个乳区发生不同种类乳腺肿瘤,分别表现为导管内乳头状癌、肌上皮细胞瘤、增生性乳腺疾病。对多发性乳腺肿瘤应确保组织病理学诊断的完整性,方可提升诊断的准确性,为临床诊断、治疗以及预后提供参考。

A 12-year-old female Pomeranian dog underwent breast lumpectomy one year ago. Multiple breast masses were found one month before the visit, and was initially diagnosed as breast tumors and pyometra by preoperative examination. Bilateral mastectomy was performed and the uterus and ovaries were removed with ultrasonic knife. After operation, anti-infective therapy and lidocaine CRI were administered for analgesia. Six months after operation, the wound of the dog recovered well and the condition was stable. Histopathological examination of the three resected tumors showed that different types of breast tumors occurred in multiple breast regions of the dog, which were manifested as intraductal papillary carcinoma, myoepithelioma, and proliferative breast disease. The integrity of histopathological diagnosis of multiple breast tumors should be ensured to improve the accuracy of diagnosis and provide reference for clinical diagnosis,treatment and prognosis.
