Thymic tumors 总被引:14,自引:0,他引:14
Thymic tumors include thymic carcinoma, which exhibit aggressive behavior, and thymomas, which manifest a more indolent course. Complete resection is the mainstay of treatment, and there appears to be little benefit to partial resection. Postoperative radiotherapy may be useful in incompletely resected patients. Preoperative chemotherapy appears to increase the rate of complete resection and survival of patients with a stage III or IVa thymoma and should strongly be considered in such cases. 相似文献

A thymic basaloid carcinoma is rare, as is an unusual case with extra-thoracic metastasis. We report on a 41-year-old woman who had a thymic basaloid carcinoma with liver metastases. The patient underwent resection of the thymic basaloid carcinoma followed by curative partial hepatectomy. At 1 year later, another metastatic lesion developed in the residual liver, which was also curatively resected. The postoperative course was uneventful, and the patient is surviving without recurrence for 12 months, to date. 相似文献

Nodular Amyloidosis Treated with a Pulsed Dye Laser 总被引:1,自引:0,他引:1
BACKGROUND: Nodular amyloidosis is a rare form of primary localized cutaneous amyloidosis which is characterized by single or multiple nodules located on the extremities, trunk, genitalia, or face. OBJECTIVE: To determine the clinical and histologic response of nodular amyloidosis to pulsed dye laser treatment. METHODS: Biopsy-proven amyloid nodules were treated with a 585-nm pulsed dye laser (average fluence 5.25 J/cm2; 10 mm spot) at 6- to 8-week time intervals. Clinical and histologic examination of laser-irradiated nodules were performed before and 6 weeks after the final laser treatment. RESULTS: Clinical improvement in the color, size, and pliability of nodules was noted and maintained for 6 months. Histologic examination revealed decreased inflammation and improvement in dermal collagen after laser irradiation. CONCLUSIONS: Since amyloid fibrils may be formed in association with dermatan sulfate-an essential matrix component in collagen fiber formation, it is postulated that the improvement seen in amyloid nodules after pulsed dye laser treatment may be attributed to a mechanism similar to that seen with hypertrophic scars. 相似文献

BACKGROUND: Thymic carcinoma is a rare, indolent, and invasive cancer. This study investigated the treatment results of thymic carcinoma and clinical prognostic factors. METHODS: From June 1988 to January 2002, 38 patients were enrolled in this study with the diagnosis of thymic carcinoma in the Cheng-Kung University Hospital based on Rosai's and Muller-Hermelink's classification. Clinical and pathologic data were retrospectively reviewed. Survival analysis was performed using the Kaplan-Meier, log rank, and Wilcoxon tests. Statistical significance was defined as p < 0.05. RESULTS: Pathology revealed 14 poorly differentiated, 6 moderately differentiated, and 8 well-differentiated squamous cell carcinomas; 8 lymphoepithelioma-like carcinomas; and 2 other carcinomas. Pathologic staging using the Masaoka system included 6 stage II, 23 stage III, and 9 stage IV patients. Six biopsies, five debulkings, and 27 complete resections were performed. All patients were followed from 15 months to 10 years 9 months, with an average of 53.8 months. Median survival time was 81 months, and median recurrence time was 52 months. Eighteen patients are still alive, and 7 are alive with disease. Well-differentiated squamous cell carcinoma had better prognosis than other carcinomas (p = 0.022). Complete resection significantly increased survival rate (p < 0.001). Tumor invasion of the superior vena cava, pulmonary vessels, or aorta were significant predictors for poor prognosis (p = 0.016, 0.002, and 0.002, respectively). CONCLUSIONS: Only patients with thymic carcinoma who underwent complete resection had long-term survival. Prognosis of thymic carcinoma seemed mainly dependent on tumor invasion of the great vessels. 相似文献

A 63-year-old man presented with dyspnea on effort. Chest computed tomography showed an anterior mediastinal mass and a lung mass in the right lower lobe. Thallium scintigraphy revealed accumulation in the mediastinal mass. Therefore, under diagnosis of invasive thymoma or thymic carcinoma associated with suspected lung cancer, exploratory right thoracotomy was undertaken through a median sternotomy with video-assisted thoracoscopic support. The lung mass was intraoperatively diagnosed as squamous cell carcinoma. Right lower lobectomy and total thymectomy were then carried out without additional incision. Thymic small cell carcinoma was diagnosed; therefore the patient received 50 Gy of irradiation to the mediastinum. Ten months after surgery the patient is alive without recurrence. 相似文献
