Metastatic adenocarcinoma of esophagus.
H&E-stained cell blocks were prepared using the plasma
thrombin (PT) (A), HistoGel (HG) (B) and CytoLyt-prefixed
thrombin (CTC) (C) clot methods. CTC and PT sections reveal
similar cellularity whereas the HG section has the least
cellularity. PT blocks showed the best cellular detail and the
least artifacts among all 3 methods (H&E, ×400).
