A rare case of primary ovarian carcinoid.

We present a rare case in an elderly Caucasian lady of primary ovarian carcinoid tumor, causing symptoms of the carcinoid syndrome and severe carcinoid heart disease. Carcinoid tumors are the commonest neuroendocrine tumors, the majority of which are found in the gastrointestinal tract and lungs. Ovarian carcinoids represent only 0.1% of all ovarian neoplasms and 1% of all carcinoid tumors. Carcinoid syndrome can present with flushing, diffuse watery diarrhea, wheezing and breathlessness and in advanced cases lead to carcinoid heart disease. This involves damage to the right heart structures and pulmonary hypertension, which can cause significant breathlessness and peripheral edema, and is associated with a worse prognosis. Diagnosis involves multi-modality radiological imaging and biochemical analysis of neuroendocrine tumor markers, and the first line treatment should always be resection of the tumor where possible. Prognosis is generally favorable, except in some cases with metastasis.
