  • This report describes the case of a 57-year-old man with an anterior mediastinal tumor. Four years previously, he underwent laparoscopic anterior resection for sigmoid colon cancer. Thirty months after that procedure, bilateral pulmonary metastasectomy was performed. Twelve months later, follow-up computed tomography revealed a 1-cm pulmonary nodule on the upper lobe of the right lung and a solid mass on the anterior mediastinum, and the patient was also observed to have an elevated serum carcinoembryonic antigen (CEA) level. Repeated pulmonary nodule resection and total thymectomy were performed. Immunohistochemical staining of the anterior mediastinal tumor revealed adenocarcinoma, and his serum CEA level returned to normal after the operation. These findings strongly suggested metastatic thymic adenocarcinoma from a colorectal cancer.

  • Good's syndrome (thymoma with immunodeficiency) is a rare cause of combined B and T cell immunodeficiency in adults. The clinical characteristics are increased susceptibility to bacterial infection and opportunistic viral and fungal infections. The most consistent immunological abnormalities are hypogammaglobulinemia and reduced or absent B cells. This syndrome should be treated by resecting the thymoma and replacing the immunoglobulin to maintain adequate IgG values. The author experienced one case of Good's Syndrome. The patient was a 64-year-old female who had a history of frequent sinopulmonary infection. Chest CT showed Pneumonia and anterior mediastinal mass and PCNB was taken and biopsy result was thymoma. She received thymectomy and replacement of immunoglobulin to control hypogammaglobulinemia.

  • We investigated the pathological changes in young rabbits which were experimentally infected with rabbit hemorrhagic disease virus (RHDV). Experimental infection of RHDV was carried out in both thymectomized and non-thymectomized young immature rabbits and adult rabbits. None of young rabbits infected with RHDV died during the experiment. Histologically, single or focal hepatocellular degeneration and necrosis with mild lymphocyte infiltration were observed in the rabbits killed at 30 hours and 5 days PI. Lymphocyte infiltration was more severe at 5 days PI than at 30 hours PI. RHDV antigens were mainly detected in the degenerating hepatocytes adjacent to the infiltrated lymphocytes at 30 hours PI and 5 days PI. In electron microscopical observation, infiltrated lymphocytes in the lesions had large nuclei without cytoplasmic granules and interdigitated with adjacent hepatocytes. It is assumed that infiltrated lymphocytes in hepatic lesions in RHDV infected young rabbits are T-lymphocytes and originate from peripheral lymphoid organs or tissues rather than from thymus.

  • Multiple primary cancer is a disease of more than two cancers occurring in an individual indepen- dently. We experienced a case of triple primary cancer, that is, lung cancer, malignant thymoma and bladder cancer which has not been reported in Korea. The patient was a 60 year old man with dyspnea and chest discomfort. He was rirst diagn sed bladder cancer and received Bricker's operation 3 months ago. At that time the chest roentgenography and computerized tomographic scan revealed as a preaortic, retrosternill medidstin;11, nlass and a lung mass at the posterior portion of the left lower lobe. On operation, there was An identillable lung mass in the left lower lobe and a thymoma already invaded the surrounding structures. So, left lower lobectomy and thymectomy were performed simul- taneously. He received one cycle of postoperative chemotherapy, but refused further management and self-discharged. He died, about one year later.

  • Myasthenia gravis with thymoma is associated with an increased risk of second malignancy, but concurrence of myasthenia gravis and thyroid carcinoma is rarely seen. In the treatment, it is emphasized to operate in two stage to avoid myasthenic crisis after surgery. In general, a thyroid cancer surgery is performed after controlling yasthenia gravis by means of thymectomy or medical treatment with steroids and anticholine esterase. We experienced two cases of thyroid carcinoma coexisting with myasthenia gravis, which is thought to be true first report in Korea.

  • 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.

  • Severe autoimmune hemolytic anemia was developed in the 45-year-old man whose anterior mediastinal growing mass, which was proved later as the invasive thymoma, had been found 4 years ago. The hemoglobin level was 6.2g/dl and both the direct and indirect Coombs' tests were positive. Prompt remission of the hemolytic anemia was achieved by thymectomy combined with corticosteroid therapy. Two months after the discontinuation of corticosteroid therapy his hemolytic anemia was recurred. The patient currently has been followed up for 8 months with no signs of local recurrence or hemolytic anemia and he is still receiving 15 mg of prednisolone daily.

  • Despite a number of recent studies on appendix its function appears to remain unknown. The present studies were undertaken in order to extend and confirm the previous studies concerning the role of appendix in immune response. An early hemagglutinin response of mercaptoethanol sensitive antibody(IgM antibody) in rabbit injected intravenously(i.v.) with 200mcg of bovine gamma globulin(BGG) was abolished by lethal whole body irradiation(900 r), but preserved in animals whose appendix and bone marrow were shielded during irradiation. Late formation of mercaptoethanol resistant antibody(IgG antibody) and the development of memory in bone marrow shielded animals were not affected by irradiation of the appendix. Formation of either IgM or IgG antibody to sheep red blood cells(SRBC) injected i.v. as determined by direct plaque forming cell(DPFC) technique in spleen were effectively abolished by appendectomy, thymectomy, or both followed by irradiation. When bone marrow was shielded in combination with autologous appendix reconstitution, DPFC response was about 5 times greater than the sum of two. Lysed appendix cells failed to restore the response. Lethally irradiated rabbits restored with combination of autologous appendix and thymus cells showed DPFC responses which were essentially normal. Three pools of appendix were obtained by manual separation technique and were stimulated with soluble concanavalin A(Con A), phytohemagglutinin-P(PHA) and pokeweed mitogen(PWM). Rabbit appendix cells responded to Con A, PHA and PWM. Cells of thymus dependent area(TDA) of the appendix were relatively enriched in their response to T cell mitogens compared to dome and follicle cells. The PHA/Con A responsive ratio of appenix TDA subpopulation was high, indicating that Con A responsive cells have a wider distribution among appendix. This finding showed that interfollicular area of the appendix is thymus-dependent. The present studies confirmed other evidence that the rabbit appendix cells itself are unable to form antibody and T lymphocytes in appendix TDA may be heterogenous, and that the appendix cells are synergistic with either bone marrow or thymus cells in the early hemagglutinin on splenic antibody response to BGG or SRBC.

  • Thymoma Is an anterior mediastinal tumor, arising from the thymus, but occasionally has ectopic focus such as neck, trachea, thyroid, pulmonary hilum, lung parenchyme and pleura. Forty-two year old male patient was admitted due to progressive development of shortness of breath in 4 months. He had a history of exposure to asbestos for About 10 years duration In recent 15 years. Radiologically, multiple pleural masses were seen rom apex to diaphrAgm, with no evidence of anterior mediastinal mass,with fluid in right pleural cavity. Closed thoracotomy drainage with open biopsy were performed. Effusion cell block showed many T cell marker positive Lymphocytes & some epithelial cells compatible with thymoma, and the tissue also showed cortical type thymoma. Pleuropneumonectomy and thymectomy followed by 60 Gy radiation therapy were done and the patient is well 8 months postoperatively. The pleura is markedly thickened by the invasion of thymoma and the interstitial space of the lung tissue,but the normal appearance of thymus was present in remote area (Masaoka classification IVa). We report a case of ectopic invasive thymoma arising from the right pleura with intact thymus.

  • Familial isolated primary hyperparathyroidism(FIPH) is associated with multiple endocrine neoplasia type 1 (MEN1) syndrome, primary hyperparathyroidism accompanied by jaw-tumor syndrome, and familial hypocalciuric hypercalcemia. FIPH may be an early stage of MEN1 or an allelic variant of MEN1. Thymic carcinoid tumor is a rare tumor in MEN1 syndrome. Here, the authors report the case of a 40-year-old man diagnosed with recurrent thymic carcinoid tumor and FIPH. Both the patient and his elder sister had been previously diagnosed to have FIPH with a novel frameshift mutation in the MEN1 gene. Initially, the patient underwent thymectomy because of an incidental finding of a mediastinal mass in his chest X-ray, and had remained asymptomatic over the following 4 years. Pancreas computed tomography conducted to evaluate MEN1 syndrome revealed anterior and middle mediastinal masses, and resultantly, massive mass excision was performed. Histological findings disclosed atypical carcinoids with infiltrative margins. In view of the thymic carcinoid tumor relapse that occurred in this patient, the authors recommend that regular pancreas and pituitary imaging studies be conducted for FIPH associated with a MEN1 gene mutation.
