Abstract
Background. Ovarian carcinoid tumors are rare, representing about 0.1 % among all ovarian tumors and 0.8 to 5 % of carcinoid tumors. Strumal carcinoid is a rare type of ovarian teratoma composed of normal thyroid tissue (struma) and a carcinoid (neuroendocrine) tumor. While most cases are benign, some may exhibit malignant features, prompting treatment as a low-potential malignancy.
Description of the clinical case. We report a case of giant ovarian strumal carcinoid with distant metastasis in the right atrium presenting as a free-floating thrombus. The patient underwent two-stage radical surgery.
Conclusion. This case report demonstrates the importance of comprehensive preoperative clinical diagnosis, intraoperative assessment and histopathological diagnosis. With this pathology, which is often asymptomatic, various diagnostic examinations have low specificity and sensitivity, and in most cases the diagnosis is based on the results of a postoperative histology examination.
