Background:
Cardiac myxoma is the most common type of primary cardiac tumor, and thymic carcinoid is a rare neuroendocrine tumor. No previous reports have described surgical management of concomitant occurrence of these neoplasms. We report a case of simultaneous surgical resection in a patient with coexisting cardiac myxoma and atypical thymic carcinoid.
Case Presentation:
A 44-year-old Japanese woman underwent chest roentgenography revealing an abnormality in the mediastinum. Computed tomography revealed a 100 mm mass in the anterior mediastinum and also a 30 mm mass in the left atrium. The mediastinal tumor was diagnosed as atypical carcinoid by biopsy. Having completed resection of atypical thymic carcinoid, cardiac mass was successfully resected with careful consideration of minimizing operation time and optimizing patient safety and oncological treatment. The histopathological diagnosis of the cardiac mass was myxoma. No adjuvant chemotherapy was administered, and no recurrence was seen as of the 45 month follow-up.
Conclusions:
The simultaneous surgery of cardiac myxoma and atypical thymic carcinoid was feasible and effective. To the best of our knowledge, this is the first case report to describe one-stage treatment of these neoplasms.
