A Rare Discovery of Neuroendocrine Tumor: Cardiac Mass.

Carcinoid tumors are rare, slow-growing neoplasms of neuroendocrine origin commonly affecting the gastrointestinal or respiratory system. They metastasize to lymph nodes and the liver based on their lymphatic and venous drainage of their tissue of origin. Metastasis to the heart is exceedingly rare accounting for <2 % of cases. Exceedingly rare is the incidental detection of cardiac carcinoid metastasis as the initial presentation of carcinoid syndrome. Here, we describe a case of metastatic cardiac carcinoid detected during a routine echocardiogram done for evaluation of a systolic murmur.
