概述
Sebaceous carcinoma of the eyelid is a rare and aggressive skin cancer that originates in the sebaceous glands of the eyelid, most commonly in the meibomian glands. It often mimics benign conditions like chalazion or blepharitis, making early diagnosis challenging.
症状
- Persistent eyelid lump or thickening
- Redness or eyelid inflammation
- Loss of eyelashes
- Recurring chalazion or stye that doesn’t respond to treatment
- Spreading lesions to conjunctiva or lymph nodes (advanced cases)
病因与风险因素
- Older age (usually >60)
- Female sex (slightly more common)
- History of radiation to the head/neck
- Immunosuppression (e.g., organ transplant recipients)
- Genetic syndromes (e.g., Muir-Torre syndrome)
诊断方法
- Slit-lamp eye examination
- Biopsy of the eyelid lesion
- Map biopsy of conjunctiva (to detect pagetoid spread)
- Imaging (MRI or CT if invasion or metastasis suspected)
治疗方案
- Surgical excision with margin control (Mohs surgery or frozen section)
- Cryotherapy for conjunctival extension
- Radiation therapy (for inoperable or recurrent cases)
- Systemic chemotherapy (in metastatic disease)
预后情况
- Localized tumors have good outcomes with complete excision
- Risk of recurrence and metastasis if not detected early
- Long-term follow-up required due to delayed recurrence potential
与此类癌症共处
- Cosmetic and functional eyelid rehabilitation post-surgery
- Psychological support for appearance-related distress
- Vision monitoring and reconstructive options if needed
预防与筛查
- Prompt evaluation of any persistent eyelid lesion
- Biopsy of recurrent chalazion or stye
- Genetic counseling for those with family cancer syndromes
