Myasthenia gravis (MG) is occasionally associated with other autoimmune diseases. Alopecia areata has been reported to coincide with MG, particularly with thymoma. A 14-year-old woman was diagnosed as having MG. Seven months before diagnosed with MG, her hair and eyebrows had began to disappear and alopecia areata was diagnosed. We report this patient as a rare case of MG associated with alopecia areata without thymoma.

Primary intrapulmonary thymomas (PITs) are defined as thymomas arising in intrapulmonary locations, without an associated mediastinal component. They are rare lesions, the diagnosis of which can be very difficult. We present a case of PIT in an asymptomatic 74-year-old woman in whom pulmonary nodules were found on pulmonary angiography performed for an episode of pulmonary embolism. She underwent wedge resection and the pathology report revealed a PIT. We also summarize this patient's clinicopathological features and discuss the diagnosis, pathogenesis, and treatment of PIT.

Pure red cell aplasia is unusual cause of anemia and a selective aplastic disorder that affects the erythroid series of the bone marrow. Fifty percent of all patients with red cell aplasia will have a thymoma. Twenty-five to 30% of those who undergo thymectomy will be cured. A 57-years-old man was admitted to the medical department of Korea University hospital with complaints. Physical examination reveals a sick looking man with a pale lip, anemic conjunctiva and subicteric sclera. On auscultation, coarse breathing sound and moist rale was heard on the right lung field. Neither the liver nor spleen was palpable. A blood count showed the erythrocytes to number 2,640,000/mm3 and hemoglobin to be 7.0gm/dl. A white blood cell count was 5,000/mm3 and a platelet count was 328,000/mm3 Reticulocyte count was 0.7%. Examination of the peripheral blood smear showed the red cell, to be normocytic and normochromic. Urine sugar was three positive and GTT was positive. The anterior-posterior and lateral view of Chest X-ray was suggestive of an anterior mediastinal mass. A bone marrow biopsy reveals absence of red cell precursors and a normal myeloid series and megakaryocytes. At thoracotomy in May 1980 an encapsulated, lobulated, benign thymoma, which measured 5x7x5 cm was removed, microscopic examination showed it was of the spindle cell type. The postoperative course was uneventful, but the patient never had a return of hemoglobin to the blood. The patient was discharged on the postoperative] 3 days. At postoperative 1 month, the patient was readmitted for bone marrow study and had no return of red cells to bone marrow. At now, patient has been treated with steroid and the further follow up study will be needed.

Background: The mediastinum is the anatomic space which is restricted and the clinical aspect varies according to location, size and type of neoplasm. Diagnostic and therapeutic approaches to mediastinal neoplasms have changed over and over. We presented our recent therapeutic experiences with these neoplasms. The object and method: The 36 patients were treated in operation from 2000 until 2006. The male patients were 20 and the female patients were 16. Age of the patients ranged from 5 to 70, and the median age was $46.4{\pm}21.9$. The child patients were two. Result: The most prevalent anatomic distribution of the neoplasm was anterosuperior mediastinum. The most common neoplasm was thymoma, followed by thymic cyst, teratoma, ganglioneuroma. The complete excison of neoplasm was accomplished in 96% of patient group except thymoma patient group. One patient underwent total thymectomy, and the other 12 patients underwent extended thymectomy from 13 thymoma patient group. In the malignant neoplasm, 7 patients were received additional treatment after operation. There was short-term death of 1 person and late death of 1 person. Conclusion: Our results except clinical manifestation are compared favorably with other reports. Surgery is the management of choice for patients with mediastinal neoplasm and early curative resection is considered to optimize clinical outcome for patients.

Aims: To study KIT (CD117) expression in thymic epithelial tumors in China, and investigate diagnostic and clinical significance. Material and Methods: Thymic epithelial tumors (TETs) from 102 patients (3 type A, 29 type AB, 5 type B1, 22 type B2, 29 typeB3 and 16 thymic carcinomas) were examined. Immunohistochemical staining with an antic-kit monoclonal antibody was performed on a tissue microarray. Relationships between KIT positive expression and the TET clinical characteristics (WHO histologic classification and Masaoka stage system) were analysed. Results: The KIT positive expression rate was significantly higher in thymic carcinoma (60%, 9/16) than in thymoma (8%, 7/86), a strong correlation being found with the WHO classification, but not the Masaoka tumor stage. The overall survival for patients with KIT positive lesions was significantly worse. Conclusions: KIT is a good molecule marker to differentially diagnose thymic carcinoma from thymoma, while also serving as a predictor of prognosis for TETs. Further research into KIT mutations in Chinese TETs should be conducted to assess the efficacy of targeted therapy.

Thymectomy has played a central role in the management of myasthenia gravis. Although both the etiology of myasthenia gravis and the reason for improvement after thymectomy remain incompletely explained, complete removal of the thymus is the logical goal of surgical treatment for this disease.From April 1989 to June 1994, maximal thymectomy was performed for 19 cases of myasthenia gravis at Chonnam National University Hospital. The results were as follows:1.Among the 19 cases, male-to-female ratio was 1:1.4, the age ranged 13 years to 71 years, and a diphasic presentation appeared with a peak in young females and a second peak in elderly males;2.Five cases were classified by modified Osserman`s classification as Group I and Group IIa and 14 cases as Group IIb and Group IIc; 3.Histologic examination of the excised thymus glands revealed normality in 5 cases [26% , thymic hyperplasia in 4 [21% , benign thymoma in 8 [42% , and malignant thymoma in 2 [11% ;4.There was no operative mortalities but two deaths occurred during the follow-up periods due to myasthenic crisis and other causes;5.The clinical improvement and the complete remission rates were 85% and 32%, respectively;6.The clinical improvement and the complete remission rates were not so good in patients with thymomas, beeing 70% and 20%, respectively; and 7.Young women with hyperplasia of the thymic tissue tended to show the best response to thymectomy.

The results were as follows: 1. The age distribution was from 6 months to 69 years old and the mean age was 32.3 years old. Of all 47 primary mediastinal tumors and cysts, 21 patients were male and 26 patients were female. 2. The neurogenic tumors[11 cases, 23.4%] were most frequently encountered and followed by thymoma[10 cases. 21.3%] and teratodermoid[9 cases, 19.1%]. 3. The anterosuperior mediastinum[59.6%] was most common tumor location, and followed by posterior mediastinum[25.6%], middle mediastinum[14.9%]. 4. The most common tumors were thymoma and teratodermoid at anterosuperior mediastinum, benign cyst at middle mediastinum, and neurogenic tumor at posterior mediastinum 5. The malignant tumors were 10 cases[21.3%] of the 47 cases and they were all symptomatic. 6. The most common chief complaint at admission was chest pain or discomfort[34%], and followed by coughing[23.4%], and dyspnea[17%]. 7. The successful complete removal was done in 37cases of benign tumors and cysts. In malignant cases, the surgical intervention was done in 3 cases, and 6 cases were treated with irradiation and chemotherapy, and 1 case was only biopsied. 8. The postoperative complications were developed in 7 cases[14.6%]. There was no case of hospital mortality.
