These data indicate that a positive interim FDG-PET/CT does not reflect persistence of active disease in the vast majority of PMBCL cases. The relapse rate appears similar regardless of interim FDG-PET/CT results and interpretation criteria. This suggests that interim FDG-PET/CT has a poor positive predictive value, thus kt should be used with caution in PMBCL.

A thoracic location of AFH has not been reported until very recently, and shares a differential diagnosis with diverse neoplasms, including spindle cell carcinoma and low-grade sarcoma. We describe the first reported case of thoracic AFH arising in a large vessel, and highlight distinctive histological and molecular features.

EBUS-TBNA may be a valuable diagnostic technique in the field of pleural pathology in selected clinical settings. More specifically 'dry' mesothelioma forming para-tracheal nodules or masses not accessible by surgery or by computed tomography/ultrasonogaphy-guided needle biopsy constitutes a good indication to perform EBUS-TBNA.
