A CASE REPORT ON BASAL CELL CARCINOMA OVER THE LATERAL BORDER OF THE EYE

Basal cell carcinoma (BCC) is the most common skin cancer, mainly affecting fair-skinned individuals and commonly occurring on sun-exposed areas of the head and neck. About 10% of cases involve the eyelids, most often the lower eyelid. Risk factors include prolonged UV exposure, fair skin, genetic syndromes, immunosuppression, radiation exposure, and tumor suppressor gene mutations. BCC usually presents as a slow-growing, painless lesion, leading to delayed diagnosis. We report a case of BCC at the lateral border of the eye treated with wide local excision and reconstruction using a mastoid flap. Histopathology confirmed complete tumor removal, and recovery was uneventful. Although BCC rarely metastasizes, eyelid involvement requires careful management due to functional and cosmetic concerns. This report highlights the clinical presentation, management, and surgical reconstruction of eyelid BCC, along with a review of current concepts in pathogenesis and treatment strategies.
