Background : Primary pericardial malignant mesothelioma is a
highly malignant and rare tumor. We present a case of primary
pericardial malignant mesothelioma in an adult male patient and review
the relevant literature to extend the understanding of the disease.
Methods: The patient underwent pericardial decortication
through the cardiopulmonary bypass, which effectively relieved the
clinical symptoms caused by the tumor blockage.
Results:Postoperative pathological diagnosis and
immunohistochemistry resulted in primary pericardial malignant
mesothelioma. The patient recovered after surgery and was followed up
regularly after discharge. Conclusions: Primary pericardial
malignant mesothelioma lacks characteristic clinical and imaging
manifestations, invariably resulting in misdiagnosis. Pathological
results combined with immunohistochemistry are the gold standard for
diagnosis. Surgery is the mainstay of treatment, but the prognosis is
