概述
Squamous cell carcinoma (SCC) of the eyelid is the second most common eyelid malignancy after basal cell carcinoma. It originates from the squamous epithelial cells and is more aggressive, with a higher potential for local invasion and metastasis.
症状
- Scaly or crusted lesion on the eyelid
- Persistent ulcer or sore
- Bleeding or non-healing lesion
- Loss of eyelashes
- Thickening or distortion of the eyelid margin
病因与风险因素
- Prolonged UV exposure
- Older age
- Fair skin and light eye color
- Human papillomavirus (HPV) infection
- Chronic inflammation or scarring
- Immunosuppression
诊断方法
- Clinical examination and slit-lamp evaluation
- Eyelid biopsy for histological confirmation
- Imaging (CT or MRI) to assess deeper invasion
- Regional lymph node evaluation
治疗方案
- Surgical excision with wide margins (Mohs micrographic surgery preferred)
- Radiation therapy for inoperable cases or adjunctive treatment
- Topical chemotherapy (rarely used, only in select cases)
- Lymph node dissection if metastasis is detected
- Reconstructive surgery to restore function and appearance
预后情况
- Early-stage disease has good outcomes with complete excision
- Higher recurrence and metastasis risk than basal cell carcinoma
- Regular long-term follow-up is essential
与此类癌症共处
- Cosmetic and functional recovery post-surgery
- Supportive care for vision and eyelid mobility
- Emotional support for coping with facial changes
- Skin cancer prevention strategies moving forward
预防与筛查
- Minimize UV exposure (sunglasses, hats, sunscreen)
- Regular skin and eye checkups
- Early biopsy of suspicious or non-healing lesions
