BACKGROUND: We believe the merit of preservation of a part of the thymus following surgery for thymoma. We evaluated the efficacy of partial or subtotal thymectomy for early-stage thymoma in the prospective study. METHODS: The Japanese Association for Research on the Thymus conducted a multiple institutional study of thymectomy for thymoma localized in the thymus without total thymectomy. Patients without autoimmune disease who had an anterior mediastinal tumor that had been clinically diagnosed as an early-stage thymoma were enrolled in the study...

Thymectomy is routinely carried out in patients with myasthenia gravis (MG) and thymomas. However, there is still a dispute as to whether MG patients with thymic hyperplasia should undergo thymectomy. We aimed to investigate the pathological findings in the thymus in patients with co-existing MG and thymic hyperplasia or thymomas treated with thymectomy, as well as effects of immunosuppression. Thirty-three patients with MG were selected and grouped accordingly: patients with no thymic abnormalities, patients with thymic hyperplasia, and patients with thymomas...

A 61-year-old woman with an abnormal radiograph shadow in her anterior mediastinum was admitted to our hospital and underwent an extended thymectomy. The pathological diagnosis of the tumor was a non-papillary adenocarcinoma of the thymus in pathological stage IV b using the Masaoka classification owing to mediastinal lymph node metastasis. We found parasternal lymph node metastases 5 months after her first operation, and subsequently, she underwent surgery and adjuvant radiotherapy. We found systemic lymph node metastases and metastatic lesions in distant organs, including her lungs, brain, and kidney 27 months after her first operation...

Although myasthenia gravis (MG) is a classic autoantibody-mediated disease, T cells are centrally involved in its pathogenesis. In recent years a number of studies have analyzed the role of CD4(+) FoxP3(+) regulatory T cells (Treg) in the disease with contradictory results. Here, the generation of Treg was significantly reduced in thymoma as compared to thymic hyperplasia and normal thymus tissue (p=0.0002). In the peripheral blood, Treg subsets classified according to CD49d, HELIOS and CD45RA expression changed after thymectomy and in the long-term course of immunosuppression...

Thymus hyperplasia associated with Sjogren's syndrome is a rare morbid state. The present study described a 55-year-old woman who presented with a dryness of the oral cavity, and itchy eyes. Chest computed tomography identified a mass, measuring 4×2.5×2.5 cm, located at the anterior mediastinum. The mass was suspected as thymoma, thymic cyst, or teratoma, and resected by thymectomy. The postoperative pathological diagnosis was thymic lymphoid hyperplasia. After 1-year follow-up period, her sicca syndrome has been resolved...

Thymoma-associated multi-organ autoimmunity disease (TAMA) is a rare paraneoplastic disorder, clinicopathologically similar to graft-versus-host disease (GVHD). Many reported cases follow a difficult course; half of them die from serious infectious diseases subsequent to immunosuppression induced by chemotherapy for unresectable thymoma, or intensive therapies including systemic steroids for complicating autoimmune diseases and GVHD-like symptoms. We report a patient whose skin symptoms were improved subsequently to total thymectomy...

A 51-year old woman was admitted with multiple cerebral, pulmonary and intra-abdominal abscesses. The combination of apparent immunosuppression, obesity, diabetes mellitus, hypertension, hypokalaemia, osteoporotic fractures and bilateral shoulder avascular necrosis led to a clinical diagnosis of Cushing's syndrome (CS). This was biochemically confirmed as follows: midnight serum cortisol 4275 nmol/L (60-250), non-suppressed overnight dexamethasone suppression test, raised salivary cortisol 716 nmol/L (5-46) and ACTH 639 ng/L (0-46)...

We present the case of a type AB thymoma in a 69-year-old man with previous coronary artery bypass grafting (CABG) in whom angiography revealed a left internal mammary artery graft supplying blood flow to a thymic neoplasm, which simultaneously occluded the graft. This required a redo sternotomy, lysis of pericardial adhesions, complete thymectomy, and redo one vessel off-pump CABG. This case seeks to sensitize physicians to the possibility of coronary adverse events in patients with a previous CABG in the setting of management of mediastinal neoplasms, and it presents the novel findings on cardiac imaging associated with this case...

Anti-PIT-1 antibody syndrome has recently been reported and characterized by acquired growth hormone (GH), prolactin (PRL), and thyroid-stimulating hormone (TSH) deficiencies associated with autoimmunity to a pituitary specific transcription factor PIT-1, which plays an essential role in GH-, PRL-, and TSH-producing cells. Although circulating anti-PIT-1 antibody and PIT-1-reactive cytotoxic T cells (CTLs) were detected in the patients, the pathophysiology and precise mechanisms for the autoimmunity remain unclarified...

OBJECTIVES: To report the results of minimally invasive surgery in patients with stage I or II thymoma in the Masaoka classification. The reference technique is partial or complete thymectomy by sternotonomy. METHODS: A retrospective single-center study of a prospective database including all cases of thymoma operated from April 2009 to February 2015 by minimally invasive techniques: either videosurgery (VATS) or robot-assisted surgery (RATS). The surgical technique, type of resection, length of hospital stay, postoperative complications and recurrences were analysed...

The actual incidence of multiple thymoma is unknown and rarely reported because it remains controversial whether the cases represent a disease of multicentric origin or a disease resulting from intrathymic metastasis. In this case, a patient underwent total thymectomy for multiple thymoma with myasthenia gravis via bilateral video-assisted thoracic surgery. A well-encapsulated multinodular cystic mass, measuring 57 mm×50 mm×22 mm in the right lobe of the thymus, and a well-encapsulated mass, measuring 32 mm×15 mm×14 mm in the left lobe, were found...

We describe the case of a patient with myasthenia gravis undergoing a robotic-assisted thymectomy complicated by postoperative myasthenic crisis, with a focus on the anesthetic considerations specific to this case. Because myasthenia gravis is an autoimmune disease affecting acetylcholine receptors, caution must be taken with the use of neuromuscular blockade and reversal. Utilizing a robotic-assisted surgical approach makes anesthetic management challenging given the dangers of patient movement while the robot is docked, lung isolation, extubation criteria, and postoperative disposition...

Naive CD4 T-cell maintenance is critical for immune competence. We investigated here the fine-tuning of homeostatic mechanisms of the naive compartment to counteract the loss of de novo CD4 T-cell generation. Adults thymectomized in early childhood during corrective cardiac surgery were grouped based on presence or absence of thymopoiesis and compared with age-matched controls. We found that the preservation of the CD31(-) subset was independent of the thymus and that its size is tightly controlled by peripheral mechanisms, including prolonged cell survival as attested by Bcl-2 levels...

Myasthenia gravis can be a debilitating neurological disorder that affects thousands worldwide. Thymectomy has historically been considered in patients refractory to medical therapy or with concurrent thymoma. While retrospective data and propensity matched trials have favored thymectomy in order to decrease disease severity and disease associated morbidity, no randomized data existed to clearly delineate the benefit of this practice. The reviewed paper by Wolfe et al. represents the first high-level randomized prospective study investigating the role of thymectomy in patients with non-thymomatous myasthenia gravis...

Trans-sternal thymectomy has long been accepted as the standard surgical procedure for thymic masses. Recently, minimally invasive methods, such as video-assisted thoracoscopic surgery (VATS) and, even more recently, non-intubated anesthesia, have emerged. These methods provide advantages including reductions in surgical trauma, postoperative associated pain, and in regards to VATS, provide certain cosmetic benefits. Considering these advantages, we herein present a case of subxiphoid uniportal VATS for thymic mass using a glasses-free 3D thoracoscopic display system...
