We report a patient with KL-6-producing invasive thymoma. A 58-year-old man was admitted complaining of dyspnea and fatigability. Computed tomography of the chest revealed interstitial pneumonia and an anterior mediastinal tumor. The tumor was surgically extirpated and diagnosed as invasive thymoma. Serum KL-6 levels later increased further and another tumor was found in the liver. That liver tumor was resected and histologically diagnosed as a metastasis of thymoma. Following resection, the serum KL-6 level decreased. Tumor cells of both primary and metastatic lesions exhibited positive reactivity to immunohistochemical staining for KL-6. A review of this case is presented.

Introduction: Complete radical resection is crucial for successfully treating thymic carcinomas. However, when the invasion of the great vessels or the heart in Masaoka III and IV stages occurs, the management poses more challenges. The R0 resection often requires neoadjuvant treatment.

Background: Neuroendocrine tumors of the thymus (NETT) are rare and malignant tumors that arise in the anterior mediastinum. These tumors can exhibit aggressive behavior and may involve surrounding critical structures, such as the superior vena cava. This case contributes to the literature by presenting a recurrent thymic carcinoma with invasion of major blood vessels, including the superior vena cava, and the complexities involved in its surgical management.

Introduction And Importance: Thymoma is the most common primary anterior mediastinal tumor in adults. Invasive thymomas infiltrate organs adjacent to the mediastinal pleura, including the lungs, great vessels, heart, pericardium, and diaphragm. Complete resection of invasive thymoma leads to a better prognosis.

Though advancements have been made in the pharmacologic treatment of myasthenia gravis (MG), surgical resection is not only an option as a last line of defense for those patients who do not respond to medical therapy but also remains vital for those with thymic epithelial tumors (TET). While prior studies have shown the potential superiority of minimally invasive approaches via robotic- and video-assisted thoracoscopic surgery (RATS/VATS) for thymectomy compared to open surgery, in the setting of malignancies, this outcome delineation is controversial. As RATS/VATS may be associated with less post-operative complications in the treatment of TET, some surgeons argue that the open approach is necessary for complete resection (R0 resection) and to prevent potential seeding of the malignancy.
