Primary thymic carcinoma is a rare malignant neoplasm which arises from the thymic epithelium. Between May 1982 and September 1990, 16 patients with thymic carcinomas, diagnosed at Chang Gung Memorial Hospital, were reviewed. Their ages ranged from 19 to 75 years, with a median of 40 years. Males predominated (male to female ratio was 11:5). The most common presenting symptoms were chest pain, cough, body weight loss and dyspnea. No paraneoplastic syndromes were seen. Chest roentgenograms of 15 patients revealed a mediastinal mass, but a definitive diagnosis could not be made until surgery. Adjacent mediastinal tissues were invaded, or adhered to, by all the tumors. Six distinct histologic types were found, squamous cell carcinoma being the most common (seven cases). The primary treatment of surgical resection was attempted in 14 patients, but only in five cases could the tumors be completely resected; two had a biopsy only. Radiotherapy, with or without chemotherapy, given postoperatively, achieved additional local control in seven of the nine partially resected patients (77%). Distant metastasis occurred in nine of 16 patients (56%). Lymph nodes, bone and lung were the most common metastatic sites. Chemotherapy with cisplatin and/or adriamycin-based regimens was given to patients who had distant metastasis, but the responses were unsatisfactory. The overall survival at one, three and five years was 88%, 51% and 31%, respectively. The median survival was 30 months. The median survival of patients with pure squamous cell carcinoma (> 49 months) was superior to that of patients with other histologic types (18 months; p < 0.01).

Sixty-one patients underwent operations for malignant thymomas between 1961 and 1989. Twenty-three patients had associated myasthenia gravis (MG), an incidence of 37.7%. Upon being admitted to the hospital, the patients' most common symptoms included chest pain, MG, cough, and dyspnea. Only 7 of 61 (11.5%) patients had no symptom. Tumor staging of 58 patients with invasive thymomas was performed according to Masaoka classification. The patients were classified as follows: Stage II disease, 5; Stage III, 41; Stage IVa, 8; and Stage IVb, 4. In addition, thymic carcinoma was present in three patients. The series had a resection rate of 55.7%. The incidence of operative complications was 16.3%. Only one patient died of myocardial infarction; the incidence of operative mortality was 1.6%. The patients with MG had a higher rate of resection (69.6%) and a higher incidence of complete thymectomy (14 of 23 patients; 60.9%). Mixed lymphoepithelial tumors and epithelial cell predominant tumors were the most frequent histologic patterns (45.9% and 34.4%, respectively). Fifty-two patients had postoperative radiation therapy, and 10 patients had chemotherapy. The overall cumulative survival rates in the series were 59% and 34% at 5 and 10 years, respectively. The results demonstrated that the factors affecting the prognosis may include resectability, postoperative irradiation or chemotherapy, MG, and tumor staging. The influence of histologic variation on survival rates could not be clearly defined in the series. Surgical resection, particularly complete thymectomy, followed by irradiation is the primary option of therapeutic management for malignant thymoma.

We would like to report on a case of thymic carcinoma that could be completely resected supported by extracorporeal circulation. A 53-year-old female complaining of severe coughing and hoarseness was admitted to our hospital. Her chest X-ray film revealed an abnormal shadow in the upper mediastinum and an elevation of the left diaphragm. Chest CT and MRI showed an anterior mediastinal mass that invaded the main pulmonary artery. The preoperative histological diagnosis of thymoma was made by mediastinoscopic specimen. After 50 Gy irradiation, surgery was performed. During the operation, after resection of the left brachiocephalic vein and a part of the upper lobe of the left lung, the tumor was detached from the wall of the aorta and resected with the invaded part of the pulmonary artery supported by cardiopulmonary bypass. Reconstruction of the pulmonary wall defect was accomplished with Xenomedica. The final pathological diagnosis was thymic adenosquamous carcinoma. The postoperative course has been uneventful 24 months after surgery. Extracorporeal circulation is a useful technique in operations involving malignant diseases when complete resection is able to be accomplished.

Nineteen cases of thymic carcinoma treated in our hospital (mean age 60.0 years, seven males and twelve females) were studied clinically. Thirteen cases (68.4%) had subjective symptom; for example, chest pain, face edema or cough. Two cases (10.5%) had the associated diseases; one had gammaglobulinemia, the other one had Cushing syndrome and hypogammaglobulinemia. The histological subtypes were eleven squamous cell carcinomas (SCC) (57.9%), three undifferentiated carcinomas, two small cell carcinomas, one papillary adenocarcinoma and one lymphoepithelioma-like carcinoma. The 5 year survival rate of all cases was 42.7%. The 10 years survival rate was 21.4%. The median survival time was 56.1 months. There were one Stage I case, nine stage III cases, four stage IVa cases and five stage IVb cases. More than stage III cases were eighteen (94.7%). Five cases of stage IVb were T2N1M0, T3N1M0, T3N0M1 and T4N0M1. The 5 year survival rate of SCC was 65.6%, and that of the other subtypes was 14.3%. The cases resected completely were only eight cases (42.1%), and the 5 year survival rate of these was 70.0%. On the other hand, the rate of five cases resected incompletely was 53.3%. Metastasis occurred in 12 cases (63.2%). Metastasis occurred frequently in pleura, lymphnode, lung, bone and liver. The radiotherapy for SCC was effective and the 5 year survival rate was 83.3%. Furthermore, there were some long survivors in the cases undergone incomplete resections by postoperative radiotherapy jointly. On the other hand, the chemotherapy was not effective in our series. However, it was reported recently that the regimen including cisplatin was effective. So it was impressed that the combined therapy including surgery radiotherapy and induction chemotherapy would be important to obtain better results.

Thymic carcinoma was found in a thymic cyst in a 60-year-old woman who was admitted to our hospital due to cough and pain in her right chest. Chest X-ray showed a huge shadow in the right mediastinum. Chest CT scan showed a cystic tumor with a solid mass. An operation revealed a solid tumor in the thymic cyst. Pathologic diagnosis was squamous cell carcinoma, that contained some glandular tissues. The patient has been in a good condition for two years after the operation. Although the concurrent occurrence of thymic carcinoma and thymic cyst is very rare, it should be added to the differential diagnosis when anterior mediastinal cystic tumor is associated with a solid mass lesion.

We report 16 cases of a distinctive variant of primary thymic epithelial neoplasm characterized by prominent spindling of the tumor cells. The patients were seven women and nine men aged 23 to 82 years (mean, 54 years). The lesions presented as anterior mediastinal masses without clinical or radiographic evidence of tumor elsewhere. Most patients had chest pain, dyspnea, and cough; in five patients, the tumors were asymptomatic and were discovered on routine clinical examination. Grossly, the lesions were firm, well-circumscribed, and locally infiltrative, and had a firm cut surface with foci of hemorrhage, necrosis, and cystic changes. Most of the tumors were treated by complete surgical excision. Histologically, they were characterized by a spindle cell proliferation showing varying degrees of atypia and mitotic activity. In 12 cases, transitions could be seen with areas that showed the features of conventional spindle cell thymoma. In two cases, areas showing features of poorly differentiated (lymphoepitheliomalike) carcinoma and anaplastic carcinoma could also be observed. Immunohistochemical studies in 10 cases showed strong positivity of the spindle tumor cells for CAM5.2 cytokeratin, and negative staining for a panel of antibodies including epithelial membrane antigen, carcinoembryonic antigen, actin, desmin, vimentin, S-100 protein, HMB45, CD34, CD5, and CD99. Clinical follow-up of eight patients showed an aggressive biologic behavior with recurrence, metastasis, and death by tumor in five of them 2 to 5 years after diagnosis. Based on these findings, the present tumors are interpreted as an unusual spindle cell variant of thymic carcinoma. The close association of these cases with areas showing the features of spindle cell thymoma within the same tumor mass suggests that some of these lesions may arise as a result of malignant transformation in a preexisting spindle cell thymoma.

We report a case of a 50 year old man referred to our department with a history of mild cough, dyspnea and dysphagia. The thoracic CT scan showed a large solid mass in the anterior mediastinum, corresponding to the findings in the chest radiographs.A 67Ga scintigraphy was performed and showed high pathological accumulation in the anterior mediastinum. A subsequent fine needle aspiration biopsy (FNAB) showed the presence of malignant cells, suggesting thymic carcinoma. Although this type of tumour is uncommon, it should be taken into account in order to establish the differential diagnosis of gallium-avid mediastinal masses.

Thymic carcinoma is a rare, highly aggressive type of tumor that typically occurs in the anterior mediastinum. We describe the case of a 73-year-old man who presented with weakness, cough, dyspnea, anorexia, and weight loss. An echocardiogram showed an intrapericardial mass that occupied the space around the lateral walls of the left ventricle and distally compressed the right ventricle. Magnetic resonance imaging and a biopsy confirmed the presence of intrapericardial primary thymic carcinoma. The patient underwent surgical excision of the tumor and died of right ventricular rupture during the procedure. This case highlights the importance of considering thymic carcinoma whenever an otherwise unexplained intrapericardial mass is encountered.

Primary thymic carcinoma-mucoepidermoid cell (MEC) type is rare and only one report describing the cytologic features of this neoplasm in the metastatic site is described. We describe the cytological features of poorly differentiated carcinoma possibly MEC in a 54-year-old man who presented with cough, weight loss, and puffiness of face for 3 months. The significance of this infrequently encountered neoplasm lies in its potential confusion of origin of the tumor-thymus or metastases from a primary bronchial MEC. Immunocytochemical profile was suggestive of a thymic carcinoma of the MEC type.

Thymic carcinoma is a rare anterior mediastinal malignancy. Most patients present initially with chest pain, cough or dyspnea. Asymptomatic patients account for less than one third of the total cases. Thymic carcinoma is aggressive and tends to metastasize to the lymph nodes, lungs, and bones, and less commonly to the liver, spleen, brain, and adrenal glands. We present a 49-year-old man who received abdominal ultrasound and magnetic resonance imaging for a health checkup, during which, a necrotic hepatic tumor was found incidentally. Fluorodeoxyglucose (FDG) positron emission tomography was performed to search for the primary site of malignancy, and lobulated FDG hypermetabolic lesions in the anterior mediastinum were found. The diagnosis of thymic carcinoma with liver metastasis was then confirmed after morphological and immunohistochemical studies of hepatic and mediastinal biopsy specimens.
