condition targeting the neuromuscular junction. Thymomas have been found in 10-15% of patients with acquired MG suggesting a paraneoplastic origin in these cases, and approximately onethird are designated as malignant with invasion of the capsule. Patients with thymoma are slightly older and more often have generalized symptoms compared to MG patients without thymoma.1 Although familial autoimm...

BACKGROUND Among human neoplasms thymomas are associated with highest frequency with paraneoplastic autoimmune diseases. CASE PRESENTATION A case of a 42-year-old woman with paraneoplastic pemphigus as the first manifestation of thymoma is reported. Transsternal complete thymoma resection achieved pemphigus regression. The clinical correlations between pemphigus and thymoma are presented. C...

Thymoma is an uncommon neoplasm derived from thymic epithelium. It is located in the anterosuperior mediastinum. Thymoma may be associated with different types of additional primary malignancies; however, colorectal adenocarcinoma and thyroid cancer appear to be most common. A case is presented of a 63-year-old woman with type A thymoma and two other primary carcinomas of the breast and colon t...

Here we a report a rare case of extralimbic encephalitis associated with thymoma. A 66-year-old woman was admitted to our hospital with cramping in her right leg and inability to walk. Magnetic resonance imaging of the brain showed multifocal high intensity signals on T2 flare images in the cerebral cortex, and chest computed tomography showed a 5-cm anterior mediastinal mass, which was conside...

introduction although thymoma is the most common anterior mediastinal tumor, only 5% of thymoma cases develop pure red cell aplasia (prca). case presentation in this article we have reported a 59-year-old man with a large anterior mediastinal mass (diameter of 10 cm) and severe anemia, that thymoma and pure red cell aplasia have been demonstrated by histopathologic and hematological examination...

Background Thymoma, though a rare tumor disease, is the most common tumor of the anterior mediastinum. However, tumor size, as a critical factor, has been underestimated. Results Age, advanced tumor stage, and preoperative radiotherapy were poor prognostic factors of overall survival (OS) and disease specific survival (DSS) (P < 0.05 for all). Besides, tumor size was significantly related to ...

OBJECTIVE We studied the clinicopathological features of type AB thymoma with liver metastases and explore the histological types, diagnosis and differential diagnosis, treatment and prognosis for this disease. METHODS Liver metastasis specimens were derived from one case of type AB thymoma 5 years after operation and were examined histologically using light microscopy and immunohistochemistr...

thymoma is the most common neoplasm of anterior mediastinum with incidence peaks during the fourth, fifth and sixth decades of life. two-thirds of patients are asymptomatic and identified accidentally by chest x-rays . of the total, 40-70 % of patients have one or more parathymic syndromes of which myasthenia gravis (mg) is the most common and reported in 10-50% . gullain-barre syndrome (gbs) h...

A case of fulminant, fatal myocarditis occurring 10 days after resection of a benign medullary thymoma is described. A rare association between thymoma and giant cell myocarditis is recognised, but fulminant presentation so soon after removal of thymoma has not previously been reported.

Paraneoplastic syndromes (PS) are the consequences of hormones or immune cross-reactivity produced by a tumor. Nephrotic syndrome (NS) is an extremely rare PS resulting from thymoma. Here, case 55-year-old woman presenting progressive generalized edema and foamy urine reported. The patient’s chest CT scan showed anterior mediastinum with intramural punctate calcification size 8.6x7.0x10.2 cm. w...
