犬低分化鳞状细胞癌的病理特点

摘要

运用病理组织学方法,观察了3例犬低分化鳞癌的病理特点,结果显示,在犬低分化鳞状细胞癌组织中,癌细胞类似于棘细胞、基底细胞,癌组织中形成癌腔,在一些癌腔内可见角化不全细胞,无癌珠形成.癌腔是低分化鳞状细胞癌的病理特点之一,可作为诊断低分化鳞状细胞癌的依据.%The histopathologic features of poorly differentiated squamous cell carcinoma in 3 dogs were observed by the histopathological method. The results showed that cancer cells were similar to the prickle cells and basal cells, cancer cavity could be seen in the cancer tissues,and parakeratotic cells in some cancer cavity, no cancer pearl occurred. The results suggested that cancer cavity was one pathological characteristic of poorly differentiated squamous cell carcinoma, and could be used as diagnos tic basis of poorly differentiated squamous cell carcinoma.
