1/103. Endobronchial brachytherapy for recurrent thymoma showing endobronchial polypoid growth.

    The authors report a case of recurrent thymoma displaying endobronchial polypoid growth. Initially, the patient had invasive thymoma with intracaval growth into the right atrium. He was treated with multimodality therapy consisting of chemotherapy, surgical resection, and radiotherapy (50.4 Gy). Both 3 years and 6 years after the initial treatment, the tumor recurred outside the reconstructed superior vena cava. The patient was treated with repeated radiotherapy (50.4 Gy and 40 Gy), and remission was achieved. Eight years after the first therapy, an endobronchial polypoid lesion was detected in the right upper lobe bronchus and was histologically found to be thymoma. Endobronchial high-dose rate brachytherapy (20 Gy at 3 mm/5 fractions) was carried out for palliation because the recurrent tumor occurred outside of the superior vena cava area, which had been reirradiated. After the treatment, the endobronchial tumor shrunk remarkably in size without adverse effects. No tumor regrowth has been noted after a follow-up of 10 months.

2/103. Bilateral pleuritis caused by legionella micdadei.

    A 58-year-old woman was hospitalized because of progressive respiratory distress. She had a history of myasthenia gravis and invasive thymoma. After thymectomy, she had been administered oral prednisolone and intrathoracic anti-cancer drugs postoperatively. Her chest radiograph revealed bilateral pleural effusions. legionella micdadei (L. micdadei) was isolated from the pleural effusions, and she was diagnosed as pleuritis caused by L. micdadei. She died despite intensive therapy with mechanical ventilation, drainage tube in the chest and intravenous erythromycin. Although only two cases of legionellosis caused by L. micdadei have been reported in japan, clinicians should be aware of L. micdadei as one of the candidates for infection in immunosuppressed hosts.

3/103. Bursting metastasis in thymic carcinoma.

    Thymic carcinomas (primitive malignant epithelial neoplasms of the thymus) are rare tumors which generally remain silent for long periods and rarely metastatize outside the chest. The authors present a case of a 49 year-old patient, with mediastinal mass complicated by pericardial effusion and rapidly extensive liver metastasis. Data in the literature indicate that completeness of the excision at initial operation is the most important prognostic factor, but the presence of necrosis, high number of mitosis and endolymphatic emboli in the specimens could indicate a poor prognosis, suggesting a tempestive treatment and a close follow-up.

4/103. Malignant thymoma with metastases to the gastrointestinal tract and ovary: a case report and literature review.

    This is the first clinical case report of a thoracic invasive thymoma metastatic to the ovary with disease noted in the entire abdomen including the pelvis 5 1/2 years after initial diagnosis. The involved areas of metastases include the distal ileum, peritoneal and serosal surfaces (including the surface of the distal colon, bladder, and pelvis), and the surface of the right ovary. The patient survived 13 years after her initial diagnosis and 7 1/2 years after discovery of her metastases. Thymomas are rare tumors but comprise the most common primary tumor of the anterior mediastinum. Extrathoracic metastases of malignant thymomas are also rare, and the literature reports that the most common sites for metastases are the liver, lung, lymph nodes, and bone. Extrathoracic disease is associated with a poor prognosis. The average time of survival after the diagnosis of metastases is 1.5 years.

5/103. Detection of occult thymoma during exercise thallium 201, technetium 99m tetrofosmin imaging for coronary artery disease.

    thallium (Tl) 201 and technetium (Tc) 99m tetrofosmin single-photon emission CT are routinely used in the evaluation of coronary artery disease. Mediastinal tumors demonstrate Tl 201 and Tc 99m tetrofosmin uptake. We report a 56-year-old man who developed chest pain after a previously successful angioplasty and stent of the left anterior descending coronary artery. He underwent a Tl 201, Tc 99m tetrofosmin exercise study. Abnormal mediastinal activity was visualized in both the Tl 201 and Tc 99m tetrofosmin images. Subsequently, the patient underwent resection of a stage II thymoma. Unanticipated focal extracardiac accumulation during myocardial scintiscanning should lead to further investigation to exclude mediastinal tumor.

6/103. thymoma with pemphigus foliaceus.

    A 75-year-old Japanese woman was referred to us because of an anterior mediastinal mass. Crusts and shallow erosions developed 10 months earlier on her upper chest, back, and scalp. pemphigus foliaceus was diagnosed based on histological examination of skin biopsy specimens and positivity for serum anti-desmoglein 1 antibody by enzyme-linked immunosorbent assay. Neurological examination and electromyography ruled out myasthenia gravis. Total thymectomy was performed, and the postoperative pathology studies showed mixed lymphoepithelial thymoma. One year after the resection, the eruption and alopecia improved and the serum anti-desmoglein 1 antibody titer decreased, suggesting a beneficial effect of thymectomy on thymoma-related pemphigus.

7/103. Intrapleural rupture of a cystic thymoma.

    Although cystic degeneration of a thymoma is not uncommon, rupture of a cystic thymoma is rare. The authors report a patient with sudden chest pain and dyspnea due to rupture of a cystic thymoma into the right pleural space.

8/103. Fulminant autoimmune cortical encephalitis associated with thymoma treated with plasma exchange.

    A 55-year-old man presented with fever, malaise, dysarthria, and intermittent twitching of his right hand. He progressed rapidly to aphasia, intractable myoclonic seizures, and unresponsiveness. magnetic resonance imaging (MRI) of the head demonstrated multiple nonenhancing areas of signal abnormality involving the cortex of both cerebral hemispheres. Extensive evaluation revealed no infectious cause for his symptoms. Muscle acetylcholine receptor binding and modulating antibodies, striational antibodies, and a neuronal autoantibody specific for collapsin response-mediator protein were detected. An invasive thymoma was discovered and resected. brain biopsy revealed microglial activation, gliosis, and scant perivascular lymphocytic inflammation. His condition worsened despite treatment with anticonvulsants, intravenous corticosteroids, and antimicrobials. plasma exchange was performed. The myoclonus stopped; he regained consciousness and gradually improved to the point that he could talk and ambulate with assistance. An MRI revealed regression of the lesions with residual cortical atrophy. This case demonstrates that paraneoplastic encephalitis may occur with thymoma and may extend to cortical regions outside the limbic system.

9/103. Good's syndrome presenting with cytomegalovirus pneumonia.

    A 61-year-old woman who had undergone an operation for thymoma 17 years previously suddenly became dyspneic and showed bilateral pulmonary infiltrates on a chest radiograph. In the bronchoalveolar lavage fluid cells contained characteristic cytomegalic inclusion bodies, as well as cytomegalovirus dna demonstrated by a polymerase chain reaction. Immunological findings included hypogammaglobulinemia, deficient numbers of circulating B cells, and impaired blast transformation of peripheral blood T cells in response to mitogens in vitro. Considering all of the findings, the patient was diagnosed with Good's syndrome presenting with cytomegalovirus pneumonia.

10/103. Ruptured thymoma causing mediastinal hemorrhage resected via partial sternotomy.

    A case of a ruptured thymoma causing mediastinal hemorrhage and hemothorax that was electively resected by a partial sternotomy approach is presented. This case and others previously reported illustrate that a sudden onset of dyspnea and chest pain accompanied by acute mediastinal widening on chest roentgenogram in a previously healthy patient should suggest the diagnosis of a ruptured thymoma. An upper part sternotomy approach may be as safe and effective as a less invasive surgical procedure in resection of noninvasive thymomas, even if dense tumor adhesion exists.
