Abstract
PURPOSE: To report a case of cicatricial ectropion and madarosis with the use of anti-epidermal growth factor receptor medication panitumumab. OBSERVATIONS: An 82-year-old man with metastatic colorectal cancer presented with cicatricial ectropion and madarosis after starting panitumumab, an anti-epidermal growth factor receptor medication used to treat metastatic colorectal cancer. His findings resolved several weeks after discontinuation of panitumumab and treatment with lubrication and antibiotic/steroid ointment. CONCLUSION: This case demonstrates the importance to consider potential medication side effects when treating periocular conditions in patients taking anti-epidermal growth factor receptor (anti-EGFR) agents.
