Clinical narrative: Myocarditis; This is a literature report.   An adolescent male patient received bnt162b2 (BNT162B2) (Batch/Lot number: unknown) as dose 2, single for covid-19 immunisation. Relevant medical history included: "attention deficit hyperactivity disorder" (unspecified if ongoing). The patient's concomitant medications were not reported. Past drug history included: Amphetamine for attention deficit hyperactivity disorder; Dextroamphetamine for attention deficit hyperactivity disorder. Vaccination history included: Covid-19 vaccine (DOSE 1; MANUFACTUERER UNKNOWN), for COVID-19 immunisation. The following information was reported: MYOCARDITIS (death), outcome "fatal", described as "Myocarditis". The patient underwent the following laboratory tests and procedures: autopsy: microscopic myocardial findings, notes: There was global myocardial injury with areas of coagulative myocytolysis and contraction bands, with a perivascular pattern of inflammation consisting of predominantly neutrophils with histiocytes, scant lymphocytes, and occasional eosinophils; body mass index: 21; gene sequencing: detected two variants of uncertain significance:, notes: DOLK  (c.1257C>G (p.Ile419Met) heterozygous) and  MAP2K2 (c.581 - 3C>T (Intronic) heterozygous); investigation: in some sections, the myocardial injury was, notes: predominantly subepicardial, while in other sections it was patchy and transmural. In the posterior wall, there was subepicardial/transmural fibrous scar, without fatty replacement. There were no acute or organizing thrombi. The overall pattern of injury was consistent with "stress cardiomyopathy" with contraction bands and a neutrophilic/histiocytic infiltrate; investigation: 280 g, notes: normal; microscopy: microscopic findings are not the alterations seen, notes: with typical myocarditis. This suggest a role for cytokine storm which may occur with an excessive inflammatory response, as there also is a feedback loop between catecholamines and cytokines; sars-cov-2 test: pcr tissue testing performed by the cdc on heart, notes: and lung found no molecular evidence of SARS-CoV-2 infection; toxicologic test: negative for medications and drugs of abuse. The patient date of death was unknown. The reported cause of death was myocarditis. The autopsy revealed "stress cardiomyopathy" (stress cardiomyopathy).  No follow-up attempts are possible. No further information is expected.; Sender's Comments: Based on the currently available information the possibility of causal association between the event myocarditis and the suspect drug BNT162B2  cannot be ruled out.
