一例犬脾脏肿瘤的病理组织学观察

Histopathological observation of the spleen tumor from a dog

通过对宠物医院接诊的1只8岁龄、患有脾脏肿瘤的公犬进行了常规的临床检查、X线检查、血液学检查,最后进行了剖腹探查手术切除脾脏肿瘤,并进行了病理组织学检查。病理组织学观察发现淋巴样细胞片状分布,圆形或近圆形、大小不等,间质中有少量网状胶原纤维,胞浆少,核深染,分裂象多见;间质中有出血和含铁血黄素细胞,中心有多个坏死灶,诊断为脾脏恶性淋巴肉瘤,为宠物临床对该病的诊治和预后提供依据。

Canine lymphosarcoma also known as malignant lymphoma is one of the most common tumors in canine tumors. A series of detailed clinical examinations for an eight-year-old dog with a spleen tumor was conducted, such as routine clinical examination, X-ray examination, hematology examination and pathological histology examination and then the splenic tumors were removed by exploratory laparotomy and pathological histology examination was carried out. Histopathological observation showed that lymphoid cells were patchy, round or nearly round, with a small amount of reticular collagen fibers in the stroma,few cytoplasm, hyperchromatic nuclei and more mitotic phenomena. There were hemorrhage and hemosiderin cells in the stroma and multiple necrotic foci in the center, thus diagnosing malignant lymphosarcoma of the spleen and providing basis for the treatment and prognosis of the disease.
