However, there are also examples of observational studies that had been established during the early years of the 20th century, were subsequently abandoned (usually after political change caused by a revolution or independence) and are being re-initiated.

As it will be described subsequently, pyothorax-associated lymphoma usually presents as a pleural mass, positive for Epstein-Barr virus (EBV) and negative for HHV8/KSHV [33].
