[Hemorrhagic pericardial effusion and multiple pulmonary nodules in a 37 year old male who has "never smoked"].

Even people which have never smoked can develop lung cancer. In this population a mutation in the exons 19-21 of the Epidermal Growth Factor Receptor (EGFR) can be detected. For this patient group targeted therapies with EGFR tyrosinkinase inhibitors are available. In this case report we describe a 37 year old non-smoker who developed a non-small cell lung cancer. Following therapy with Erlotinib a partial response could be achieved.
