We present a case who had left upper lobectomy with total vertebrectomy after arterial embolization in preparation for intraoperative bleeding. A 35-year-old man complained of left back pain. Chest CT revealed a tumor in S1+2 of the left lung, invading the third thoracic vertebra. As no nodal or distant metastasis was detected, we performed left upper(More)
BACKGROUND Circulating tumor cells (CTCs) are tumor cells that are shed from primary tumors and circulate in the peripheral blood. CTCs, as a surrogate of micro-metastasis, can be a useful clinical marker, but their clinical significance remains unclear in lung cancer. We now report a case of lung cancer in which the count of CTCs was useful in monitoring(More)
INTRODUCTION Surgery for primary lung cancer invading the spine remains challenging. Here, we present a case of superior sulcus tumor (SST) with vertebral invasion, successfully resected with total vertebrectomy (Th2) and dissection of involved apical chest wall and the subclavian artery (SCA). PRESENTATION OF CASE A 62-year-old man was referred with the(More)
BACKGROUND Pleomorphic lung cancer cells have been reported to produce cytokines, resulting in systemic reactions. Recently, the autonomous production of hematopoietic cytokines (granulocyte colony-stimulating factor [G-CSF], granulocyte-macrophage colony-stimulating factor [GM-CSF], and interleukin-6 [IL-6]) was observed in some of these patients. CASE(More)
BACKGROUND Thymic carcinomas are usually detected in the anterior mediastinum. Thymic carcinoma occurring in the middle mediastinum and showing an image of a cyst is extremely rare. CASE PRESENTATION A 64-year-old man with a middle mediastinal tumor detected incidentally by a CT scan was referred. Chest CT showed an entirely cystic mass in the middle(More)
BACKGROUND Surgery for lung cancer invading the spine remains challenging associated with high morbidity and mortality. However, recent advances in surgical techniques as well as in perioperative care may improve outcomes of lung cancer surgery with vertebrectomy. We describe our surgical approach and assess the outcome lung cancer invading the spine. (More)
BACKGROUND Resection and reconstruction of the pulmonary artery during lobectomy is a safe and effective procedure for centrally located lung cancer. We usually choose a pericardial conduit to repair a large defect of the pulmonary artery. The use of an autologous pulmonary vein conduit for reconstruction was first described in 2009. CASE PRESENTATION A(More)
Tyrosine kinase inhibitors (TKIs) of the epidermal growth factor receptor (EGFR) may achieve long-term survival in selected cases with advanced non-small cell lung cancer harboring activating mutations in the EGFR gene, but a cured case has not been reported yet. Here, we present the first case of EGFR-mutated lung adenocarcinoma cured with an EGFR-TKI, as(More)
We present the first case of small cell lung cancer with Lambert-Eaton myasthenic syndrome during hemodialysis (HD). A 72-year-old male patient receiving HD experienced progressive muscle weakness. He was diagnosed with small cell lung cancer with Lambert-Eaton myasthenic syndrome due to an increased serum level of anti-voltage-gated calcium channel(More)
Here, we present the first case of post-thymectomy Myasthenia Gravis with onset at Osserman stage III. An 81-year-old woman was admitted for an abnormal shadow seen in a chest radiograph. She had no symptoms of Myasthenia Gravis. Acetylcholine receptor antibody was within the normal range. Chest computed tomography (CT) showed a bulky anterior mediastinal(More)
