Primary cardiac mesothelioma presenting with fulminant recurrent pericarditis: a case report.

Primary pericardial mesothelial should be considered in the differential diagnosis of refractory recurrent pericarditis, even with prior biopsy-proven pericarditis or when a putative trigger (COVID-19 mRNA prior vaccination) is suspected, as was the case in this patient. Tumour diagnosis and identification consist of multimodal imaging and laboratory tests. A multidisciplinary, individualized care approach should be performed.
