Myasthenia gravis can develop after resection of thymic tumors. Post-thymectomy myasthenia gravis can be heralded by elevated preoperative anti-acetylcholine-receptor antibodies. Thymic tissue in isolated mediastinal areas can be the culprit lesion and identified by PET SCAN. Re-resection in selected patients can lead to remission of this rare disease.

In jawed vertebrates from sharks to mammals, the thymus is the primary (or central) lymphoid tissue where T cells develop and mature. The particular stromal cell types, cytokine environment, and tissue organization in the thymus are essential for V(D)J recombination, positive selection for major histocompatibility complex recognition, and negative selection against self-peptide recognition of most αβ T cells. The thymectomy operation on Xenopus tadpole larva described here creates a T-cell-deficient model suitable for many immunology studies...

INTRODUCTION: Thirty to fifty percent of thymoma patients develop myasthenia gravis (MG). In 1.5-28% of cases, MG appears many years after removal of a thymoma. PATIENTS AND METHODS: We present a case report of a 72-year-old female who presented with MG four months after total thymectomy. RESULTS: A 72-year-old female patient presents with MG four months after total thymectomy. Imaging revealed a PET-positive nodule anterior to the superior vena cava...

We report a surgical case of micronodular thymoma with lymphoid stroma (MNT), which is a rare type of thymoma. A 66-year-old man was referred to our hospital for further examination and treatment of a nodule in the mediastinum. Computed tomography(CT) showed a 20-mm nodule in the anterior mediastinum, and positron emission tomography-CT showed slight uptake in the same region. Thymoma was suspected and videoassisted thymectomy was performed. Histopathological findings showed spindleshaped tumor cells forming storiform, with the background of lymphoid stroma, and the tumor was diagnosed as MNT...

Background: The approaches to thoracoscopic thymectomy in myasthenia gravis (MG) are debatable. We developed a novel approach via subxiphoid and subcostal arch, with a significantly shorter duration of operation and hospital stay, less estimated blood loss, and lower postoperative pain. Methods: From December 2012 to December 2014, 77 myasthenia gravis patients with or without thymoma underwent thoracoscopic extended thymectomy at our hospital. Among them, 41 patients were operated via the subxiphoid and subcostal arch approach and the other 36 via the conventional unilateral approach...

Background: Trans-subxiphoid thoracoscopic thymectomy is a promising procedure but technically demanding associated with ergonomic discomfort. In order to facilitate this complex procedure, the authors present a modified trans-subxiphoid thymectomy by the use of the Da Vinci robotic system. Methods: A 2-cm longitudinal incision for camera was made below the xiphoid process. Through this incision, the space among the posterior surface of the sternum, bilateral mediastinal pleura and diaphragm (extra pleural space) was enlarged blindly with a finger...

The aim of this study was to analyse the feasibility and safety of robotic-assisted thymectomy (RoT) in patients with clinically early stage thymoma, investigating clinical and early oncological results. Between 1998 and 2017, we retrospectively reviewed 76 (42.2%) patients who underwent radical thymectomy for clinically early stage thymoma (Masaoka-Koga I and II), identifying all patients who underwent RoT (n = 28) or open thymectomy (OT) with eligibility criteria for robotic surgery (n = 48). Using a propensity-score matched for tumor size (3...

OBJECTIVE: Thymectomy considered as a standard procedure in treatment of all the steps of myasthenia gravis. Video-assisted thoracoscopic surgery (VATS) thymectomy is one of the minimally invasive procedures that because of the short duration of hospitalization, less postoperative pain, and scar after surgery, nowadays it is replaced the traditional methods of surgery for patients with myasthenia gravis, but there are still differences and concerns. The aim of this study was to compare outcomes of two different techniques of surgery, VATS versus transsternal (TS) in the treatment of myasthenia gravis...

Thymomas are the most common masses located in the anterior mediastinum, and they are often associated with autoimmune disorders including myasthenia gravis, polymyositis, and aplastic anemia (AA). Autoreactive T-cell clones generated by the thymoma may lead to autoimmune disorders. We report the case of a 14-year-old boy who was examined for AA, and the underlying cause was determined to be an immune-mediated complication of thymoma. He had no matched sibling donors. He underwent thymectomy, and 3 months later he was treated with immunosuppressive therapy (IST), consisting of antithymocyte globulin and cyclosporine A...

The rapid growth in published medical literature makes it difficult for clinicians to keep up with advances in their fields. This may result in a cursory scan of the abstracts and conclusions of a study without critically evaluating study quality. The application of Evidence-Based Medicine (EBM) is the process of converting the abstract task of reading the literature into a practical method of using the literature to inform care in a specific clinical context while simultaneously expanding one's knowledge. EBM involves 4 steps: stating the clinical problem in a defined question; searching the literature for the evidence; critically appraising the evidence for its validity and applying the evidence in the context of the patient's situation, preferences and values...

Background: The co-existence of myasthenia gravis (MG) and thymoma makes the surgical treatment more complicated and adjuvant radiation more controversial. The aim of this study was to investigate adjuvant radiotherapy for thymoma with MG after extended thymectomy. Methods: A total of 181 patients with both MG and thymoma were recruited between 2003 and 2014 at Tongren Hospital, China. Among all the patients, 157 patients received radiation therapy after surgery (Group A); whereas the other 24 patients did not receive radiation therapy (Group B)...

With specialized care, patients with myasthenia gravis can have very good outcomes. The mainstays of treatment are acetylcholinesterase inhibitors, and immunosuppressive and immunomodulatory therapies. There is good evidence thymectomy is beneficial in thymomatous and nonthymomatous disease. Nearly all of the drugs used for MG are considered "off-label." The 2 exceptions are acetylcholinesterase inhibitors and complement inhibition with eculizumab, which was recently approved by the US Food and Drug Administration for myasthenia gravis...

Background: Robotic thymectomy has been suggested a feasible and safe approach for myasthenia gravis (MG). Few investigations have revealed the independent effect of robotic thymectomy without the confounding impact of immunosuppressive (IM) therapy. Methods: Between May 2009 and December 2012, robotic extended thymectomy was carried out for patients with diagnosis of MG. The clinical data, subsequent neurological therapy and postintervention status were collected...

Myasthenia gravis is associated in 10 to 15 percent of patients with thymic tumors, rarely with aplastic anemia. We report a 45-year-old male diagnosed with myasthenia gravis -associated with thymoma. We started treatment with pyridostigmine. After thymectomy, the patient -received 30 irradiation sessions. In the postoperative course, he had mild worsening of myasthenia gravis, which improved with prednisone. Five months later, he developed severe aplastic anemia. He was dependent on blood supplement. After allogeneic transplantation of bone marrow, he improved but later he -developed graft versus host disease...

Surgery is the most important therapy for thymic malignances. The last decade has seen increasing adoption of minimally invasive surgery (MIS) for thymectomy. MIS for early stage thymoma patients has been shown to yield similar oncological results while being helpful in minimize surgical trauma, improving postoperative recovery, and reduce incisional pain. Meanwhile, With the advance in surgical techniques, the patients with locally advanced thymic tumors, preoperative induction therapies or recurrent diseases, may also benefit from MIS in selected cases...

Until recently, the surgical approach to thymic tumors has remained basically unchanged. The collaborative effort led by ITMIG with the collaboration of regional and society-based interest groups (ESTS, JART) produced an enthusiastic surge of interest in testing the new technological advances in thoracic surgery and many historical dogmas in thymic surgery have been questioned and challenged. The present review addresses the new trends in the optimal surgical management of thymic tumors based on the review of the current literature...
