  Abstract

Cardiac metastatic squamous cell laryngeal carcinoma is rare. We report the case of a 49-year-old man with recurrent squamous laryngeal carcinoma presenting with right leg acute ischaemia and large mobile right and left cardiac masses. The patient has history of laryngeal squamous cell cancer surgically treated with total laryngectomy, thyroidectomy, and tracheostomy 2 years ago. He was admitted to our intensive care unit with acute right leg pain, left sided chest pain, hypotension 92/55, and tachycardia 112 bpm. On physical exam, he had a faint pulse of his right Posterior Tibial artery with a cold foot, but no discoloration. Heart sounds were normal with no murmur. Initial workup showed a Troponin of 0.27. An electrocardiogram showed sinus tachycardia, with inverted T waves in the Infero-lateral leads. Emergent surgical thrombectomy was done on his right leg with restoration of arterial blood flow to the affected limb. An echocardiogram showed a preserved left ventricular function with multiple areas of echogenic masses in all four cardiac chambers located at the annulus of the tricuspid valve, the right ventricular free wall and along the inter-ventricular septum. No intracardiac shunt was detected by contrast study. Computed tomography scan of the heart confirmed the presence of multiple exophytic intracardiac masses within the left atrium, the right ventricle, interventricular septum, and lateral free wall of the left ventricle. Immunohistochemical staining with cytokeratin of the emboli was consistent with malignant squamous cell carcinoma consistent with metastases of his known laryngeal squamous cell cancer.
