眼睑基底细胞癌的临床病理研究

对１８例眼睑基底细胞癌进行临床和病理分析，基底细胞癌是眼睑恶性肿瘤最多见的一种，主要发生于５０岁以上的老人，好发于下睑内眦部；病变早期为小结节状，晚期形成侵蚀性溃疡，病程缓慢。很少转移。该肿瘤在病理形态上具有基本组织结构特征；基底细胞样细胞形成团块和网状条索，外周细胞呈栅栏状排列。眼睑基底细胞癌易与眼睑的鳞癌、睑板腺癌混淆，造成误诊。并对其诊断、鉴别诊断及影响预后因素等进行讨论。

A clinicopathologic study of basal cell carcinoma of the eyelids

18 cases of basal cell carcinoma (BCC) of the eyelids were analyzed clinically and pathologically. BCC, as the commonest malignant tumor, chiefly occurs in peple over 50 years old and usually in the inner canthus of inferior eyelids. Its shape changes from small nodule in the early stage to erosive ulcer in the later. It grows slowly and metastasis is rare. The main morphologic feature of BCC is that the basaloid cells are arranged in sheets or cords with palisading peripheral cells. BCC is easy to be confused with squamous cell carcinoma or meibomian gland adenocarcinoma. The diagnosis, differential diagnosis of BCC and the factors influencing prognosis were also discussed.
