Core Tip |
A tumor in the femur was identified genetically as a lung cancer metastasis. This case suggests that a matching epidermal growth factor receptor (EGFR) mutation in a distant lesion can validate a diagnosis of lung cancer metastasis, even if it differs histologically from the primary lesion. To the best of our knowledge, this is the first report showing the use of EGFR genetic analysis to identify a distant lesion as a lung cancer metastasis. In the era of molecularly-targeted treatments for non-small cell lung cancer, combined pathological diagnosis and genetic analysis could lead to more precise diagnoses and better understanding of histogenesis and more appropriate therapeutic selections. |
