Novel skin toxicity of epidermal growth factor receptor inhibitors: A case of intertrigo-like eruption in a patient with metastatic colorectal cancer treated with cetuximab

Over the recent years, targeted therapy has become one of the most important innovations in cancer treatment. Agents targeting the epidermal growth factor receptor (EGFR) are administered in patients with advanced, recurrent, and metastatic malignancy. Skin toxicity is one of the most common side effects of EGFR inhibitors. In this report, we present the case of a 70 year-old male patient with metastatic colorectal cancer who developed an intertrigo-like eruption during molecular target therapy with cetuximab treated with topical corticosteroid. A complete remission was obtained after 4 weeks.
