Abstract

Background: Meningiomas have been shown to express mesothelin, a high affinity binding site for MUC16, a transmembrane protein on adenocarcinoma cells. The mechanisms underlying adenocarcinoma metastases to meningiomas may provide insight into tumor-to-tumor metastases and adenocarcinoma metastases to leptomeningeal cells. Methods: Two meningiomas containing metastases from adenocarcinomas were identified and evaluated immunohistochemically for the expression and localization of mesothelin and MUC16. Results: Both meningiomas show extensive mesothelin immunoreactivity, and the adenocarcinomas metastatic to the meningiomas show mesothelin and MUC16 immunoreactivity at the interface with meningioma. Conclusions: Interactions between MUC16 and/or mesothelin on the cell membrane of adenocarcinoma cells with mesothelin on meningioma cells may facilitate adenocarcinoma metastases to meningiomas and possibly the leptomeninges.
