A recent systematic review and meta-analysis by Turner et al. further confirmed that meningioma is the most common recipient tumor in tumor-to-tumor metastasis, likely owing to its vascularity and unique biological microenvironment [4]. Despite meningioma being the most common recipient tumor, tumor-to-tumor metastasis remains exceptionally rare in lung cancer, and recurrence of epidermal growth factor receptor (EGFR)-mutated adenocarcinoma through this route has not been previously reported. This evidence concerns the gene EGFR and meningioma.
