C44.139

Clinical Causes: Unclear exact cause, but potential risk factors include genetic predisposition and certain inherited syndromes. Long-term exposure to ultraviolet (UV) radiation from sunlight can increase risk. Chronic skin inflammation or previous skin injuries in the eyelid area may contribute. Age-related changes that weaken skin integrity and immune surveillance. Presence of certain genetic conditions, such as Muir-Torre syndrome, which predispose individuals to sebaceous carcinomas.

Key Symptoms: A painless, firm, yellowish or whitish lump or nodule on the eyelid. A bump that slowly enlarges over months or years. A persistent, ulcerated skin lesion that may sometimes bleed or crust. Changes in skin color or texture in the affected area. A misaligned eyelid or drooping eyelid (ptosis) in some cases. Possible swelling in the eye or surrounding tissues. Visual disturbances are rare but can occur if the tumor invades nearby structures.

Diagnosis Path: Biopsy of the lesion: A tissue sample is taken and examined microscopically to confirm cancer type. Imaging studies such as ultrasound, MRI, or CT scans may be used to assess the tumor’s extent and involvement of neighboring structures. Histopathological analysis to distinguish it from other skin cancers or benign lesions. Additional genetic testing may be recommended, especially if associated with syndromes like Muir-Torre.

Treatment Protocols: Surgical excision: The primary treatment is often surgical removal of the tumor with clear margins to ensure complete excision. Mohs micrographic surgery: A precise surgical method that removes the cancer layer by layer while sparing healthy tissue, ideal for eyelid cancers. Radiation therapy: May be used as an adjunct or alternative when surgery isn't feasible. Cryotherapy or topical chemotherapy: Less common, typically used for superficial lesions. Reconstructive surgery: Often necessary to restore eyelid appearance and function after tumor removal.
