Cardiac micrometastasis of maxillary squamous cell carcinoma: A rare postmortem finding

Secondary cardiac tumors are rare with an incidence of 2.3%. Common tumors metastasizing to the heart are lung, esophagus, breast, stomach, pancreas, melanoma, and colon. Only few case reports of oral squamous cell carcinoma metastasizing to the heart have been reported. Herein, we are presenting a case of a 17-year-old deceased male previously diagnosed with maxillary squamous cell carcinoma, found having multiple micrometastatic foci to the heart and lung in histopathological examination of tissues received after conducting autopsy. The involvement was limited to the myocardium with a normal pericardium and endocardium, which is not common. The case details and relevant clinical discussion are described to highlight asymptomatic, grossly inappreciable, micrometastatic foci of oral squamous cell carcinoma to myocardium.
