Abstract

Carcinoid syndrome (CS) is a unique constellation of symptoms caused by release of vasoactive substances from neuroendocrine tumors (Pandit et al., StatPearls, 2022). Neuroendocrine tumors are rare with an annual incidence of 2 in 100,000 people (Ram et al., 46:21-27, 2019). Up to 50% of patients with these tumors will develop carcinoid syndrome, which is characterized by symptoms caused by elevated levels of serotonin and most commonly include fatigue, flushing, wheezing, and non-specific gastrointestinal symptoms such as diarrhea and malabsorption (Pandit et al., StatPearls, 2022) (Fox et.al., 90:1224-1228, 2004). Over time, patients with carcinoid syndrome can develop carcinoid heart disease (CHD). CHD refers to the cardiac complications that occur when the vasoactive substances, such as serotonin, tachykinins, and prostaglandins, secreted from the carcinoid tumors. These complications most commonly include valvular abnormalities, but can also present as coronary artery damage, arrhythmias or direct myocardial injury (Ram et al., 46:21-27, 2019). While CHD is not typically an initial feature of carcinoid syndrome, it does eventually occur in up to 70% of patients with carcinoid tumors (Ram et al., 46:21-27, 2019) (Jin et.al., 146:65-73, 2021) (Macfie et.al., 224:665-669, 2022). CHD is associated with significant morbidity and mortality due to the risk of progressive heart failure (Bober et.al., 14:1179546820968101, 2020). In this case, we describe a 35-year-old Hispanic woman in South Texas with undiagnosed carcinoid syndrome for over 10 years that eventually progressed to severe CHD. In this patient’s case, we emphasize how lack of access to healthcare resulted in delay of diagnosis, appropriate treatment, and worsened prognosis in this young patient.
