In A 64-year-old female who was clinically diagnosed to have constrictive pericarditio cerebral infarct which caused death occurred. Autopsy was carried out. We confirmed the primary malignant mesothelioma of pericardium and discussed the tumor imprint cytology.
Characteristic findings of tumor imprint cytology were as follow: 1) Adenocarcinoma-like round cells and spindle-like malignant tumor cells coexisted.
2) Intercellular combination was dense.
3) Average diameter of tumor cells was 20μ to 300μ.
4) Blister-like cytoplasm was pale and fine vesicular.
5) Nucleolei were 3μto 4μin size and were small and round.
6) Glycogen granules, fibrilles, desmosomes and microvilli were revealed under electron microscope.
We diagnosed this case as a primary pericardial malignant mesothelioma.
