Abstract The therapeutic use of monoclonal antibodies against the epidermal growth factor receptor EGFR is specifically associated with dermatologic reactions of variable severity. Recent evidence suggests superiority of the EGFR inhibitor EGFRI cetuximab plus radiotherapy compared to radiotherapy alone in patients with squamous cell carcinoma of the head and neck. Although not documented in a study population several reports indicate a possible overlap between radiation dermatitis and the EGFRI-induced skin rash. We here present a case of severe skin reaction secondary to the addition of cetuximab to radiotherapy. Findings A 56-year-old woman with squamous cell cancer of the head and neck received primary chemoradiation at our institution. Due to thrombocytopenia chemotherapy had to be stopped early and was replaced by the EGFR inhibitor cetuximab. In a close temporal relationship to the first dose exacerbation of a pre-existing grade 1 radiation erythema occurred within the high-dose radiation portals. Clinically features of both the EGFRI-induced acne-like rash .
