Basal cell and squamous cell carcinomas are actinic lesions that must be considered in the differential diagnosis of growths of the eyelid. Basal cell carcinoma is the most common eyelid cancer. It tends to grow slowly, and rarely if ever metastasizes. Basal cell carcinoma can, however, grow by direct extension to adjacent structures including the brain. Basal cell carcinoma can be managed by Moh's surgery, excision, cryosurgery, radiation, and chemotherapy. Squamous cell carcinoma has similar epidemiology to basal cell carcinoma. However, it grows much faster and it can metastasize (up to 20% of the time). It is best managed by conventional surgery, cryosurgery, and sometimes radiation. Squamous cell carcinoma can have a grim prognosis if not detected and treated promptly.
基底细胞癌和鳞状细胞癌是光化性病变，在眼睑肿物的鉴别诊断中必须予以考虑。基底细胞癌是最常见的眼睑癌。它往往生长缓慢，很少发生转移。然而，基底细胞癌可通过直接蔓延至包括脑在内的邻近结构。基底细胞癌可采用莫氏手术、切除术、冷冻手术、放疗和化疗进行治疗。鳞状细胞癌的流行病学特征与基底细胞癌相似。然而，它生长速度快得多，且可发生转移（转移几率高达20%）。其最佳治疗方法是传统手术、冷冻手术，有时也采用放疗。鳞状细胞癌如果未及时发现和治疗，预后可能很差。
