Tóm tắt

AbstractThis paper reports a case of fulminant giant cell myocarditis arising in association with a malignant thymoma causing death in a 46‐year‐old woman. Although the diagnosis was suspected in life, postmortem examination was required for confirmation of giant cell myocarditis. Consent was obtained only for percutaneous needle biopsy of the heart. In order to respect the family's wishes and harvest sufficient diagnostic myocardium, a simple needle‐based biopsy technique was devised. A bone marrow trephine needle was attached to a 20 ml syringe and, with suction, multiple passes were used to fill 15 tissue cassettes. The cores were placed immediately in formalin and B5 fixatives. High‐quality tissue preservation was obtained without crush artefact. Immunohistochemical studies of the biopsy tissue confirmed that the giant cells were of macrophage derivation.
