Thymomas are rare epithelial mediastinal tumors showing a certain propensity for local and intrathoracic recurrences. Otherwise, extrathoracic metastases are very rarely reported and are usually associated with type B thymomas or thymic carcinomas. We present a challenging patient with an invasive (Masaoka-Koga stage IIb) medullary type A thymoma with recurrent extrathoracic metastases (pulmonary and vertebral localizations occurring 2 and 7 years after the initial radical thymectomy, respectively). Despite type A thymoma being considered a low-grade malignancy with a scarce propensity to recurrence, the present case should alert clinicians to the possibility of bone metastasis...

In recent years, thymectomy has become a widespread procedure in the treatment of myasthenia gravis (MG). Likelihood of remission was highest in preoperative mild disease classification (Osserman classification 1, 2A). In absence of thymoma or hyperplasia, there was no relationship between age and gender in remission with thymectomy. In MG treatment, randomized trials that compare conservative treatment with thymectomy have started, recently. As with non-randomized trials, remission with thymectomy in MG treatment was better than conservative treatment with only medication...

A 71-year-old man presented with a thymic mass involving the superior vena cava. A mediastinoscopical biopsy initially suggested a diagnosis of type A thymoma. After neoadjuvant chemotherapy, the patient underwent en-bloc thymectomy and vascular resection for a pathology-confirmed type B3 thymoma involving the superior vena cava, the left brachiocephalic vein and the distal part of the right brachiocephalic vein. Adjuvant radiotherapy was administered. Two years after the primary surgery, abdominal computed tomography (CT) and whole body fluorodeoxyglucose (18-FDG) positron emission tomography (PET) scans showed a single hepatic lesion that was treated with wedge liver resection...

OBJECTIVE: Delayed post-operative ambulation is a risk of post-operative complications and increases overall healthcare costs. We investigated pre-operative and intraoperative variables associated with delayed ambulation in patients who underwent thymectomy. METHODS: A total of 57 consecutive patients undergoing thymectomy were included in this study. Pre-operative functional exercise capacity was evaluated by six-minute walk distance. Ambulation was considered to be delayed if the patient could not walk the ward on post-operative day 1...

BACKGROUND: The role of thymectomy in the treatment of juvenile myasthenia gravis (JMG) is poorly defined. The objective of this systematic review was to evaluate the effect of thymectomy on survival, disease severity, and peri-operative complications for patients with JMG. METHODS: A search of MEDLINE, EMBASE, and the Cochrane Library (1/1/2000-3/1/2016) identified all English language, human studies of thymectomy for JMG. The population was patients with JMG age ≤18 years who underwent thymectomy (comparator group was unexposed to thymectomy)...

Paraneoplastic pemphigus is a rare, life-threatening autoimmune mucocutaneous blistering disease associated with underlying neoplasia, commonly lymphoproliferative tumors. Herein we report a case of paraneoplastic pemphigus with a unique autoantibody profile associated with a malignant thymoma. A 56-year-old female patient presented with relapsing oral ulcerations accompanied by erythematous papules and patches on her extremities for 2 months. Skin and mucosal biopsies identified interface dermatitis with lichenoid lymphocytic infiltration in the upper dermis...

BACKGROUND: Myasthenia gravis (MG) is an autoimmune disease caused by antibodies to acetylcholine receptors of the skeletal muscle. Myasthenic crisis (MC) is a complication observed during both early and late stage MG cases. In this study, we examined current treatments and three years outcomes in patients with MG and MC. We also investigated the impact of thymectomy and systemic lupus erythematosus (SLE) in patients with MG and MC. METHODS: In this retrospective study, we reviewed the medical records of all patients admitted to one teaching hospital between January 2006 and December 2014 and identified those for whom discharge diagnosis included the International Classification of Diseases, ninth revision (ICD-9) codes corresponding to MG (358...

Pure red cell aplasia (PRCA) and hypogammaglobulinemia are paraneoplastic syndromes that are rarer than myasthenia gravis in patients with thymoma. Good syndrome coexisting with PRCA is an extremely rare pathology. We report the case of a 50-year-old man with thymoma and PRCA associated with Good syndrome who achieved complete PRCA remission after thymectomy and postoperative immunosuppressive therapy, and provide a review of the pertinent literature.

The prognosis of myasthenia gravis (MG) in association with invasive or metastatic thymoma is usually worse, and therapeutic options are quite limited. Here, we retrospectively reported the therapeutic effect of docetaxel plus cisplatin (docetaxel/cisplatin) chemotherapy in 7 MG patients with metastatic thymoma. Previously, all patients underwent thymectomy at the first onset of thymoma. After the metastasis of thymoma, none of the patients received thymectomy due to unresectable conditions after surgeon's evaluation for great risk of myasthenic crisis (n = 5) or patients' refusal (n = 2)...

OBJECTIVES: Thoracoscopic surgery is widely used for the surgical treatment of thymoma. However, large-sized thymomas are typically treated using open surgery. This study evaluated the feasibility of performing thoracoscopic thymectomy (TT) for thymoma ≥50 mm. METHODS: A retrospective review was conducted on 135 patients who underwent TT or open thymectomy (OT) for Masaoka stage I-IVa thymoma between 1996 and 2014. RESULTS: Patients were first divided into two groups based on thymoma size: thymoma ≥50 mm and thymoma <50 mm groups...

The association between thymoma and autoimmunity is well known. Besides myasthenia gravis, which is found in 15 to 20% of patients with thymoma, other autoimmune diseases have been reported: erythroblastopenia, systemic lupus erythematosus, inflammatory myopathies, thyroid disorders, Isaac's syndrome or Good's syndrome. More anecdotally, Morvan's syndrome, limbic encephalitis, other autoimmune cytopenias, autoimmune hepatitis, and bullous skin diseases (pemphigus, lichen) have been reported. Autoimmune diseases occur most often before thymectomy, but they can be discovered at the time of surgery or later...

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...
