Panitumumab-Induced Eruptive Seborrhoeic Keratosis in a Patient with Metastatic Colorectal Cancer
KeywordsPanitumumab, eruptive seborrhoeic keratosis, drug-induced eruption
Objectives: Agents targeting the epidermal growth factor receptor (EGFR)-mediated signalling pathway are increasingly being used for the treatment of advanced lung, pancreatic, colorectal and head and neck cancers.
Case presentation: Here, we report the first case of eruptive seborrhoeic keratosis following panitumumab treatment, an anti-EGFR monoclonal antibody, in a 73-year-old patient with stage 4 (IV) colorectal cancer with hepatic metastasis.
Conclusion: While panitumumab is an emerging therapy for RAS wild-type metastatic colorectal cancer, physicians should consider panitumumab as a potential cause of eruptive seborrhoeic keratosis.
