An autopsy case of an 18-year-old boy with adenocarcinoma of the lung is reported. He experienced dyspnea and hemosputum in July 1988. Chest radiographs showed a diffuse bilateral streaky shadow, bilateral pleural effusion and cardiac enlargement. The diagnosis of adenocarcinoma was made by transbronchial biopsy at another hospital. He visited the National Cancer Center Hospital on October 7, 1988. The diagnosis of lung cancer was strongly suggested by positive immunohistochemical staining for pulmonary surfactant apoprotein in biopsy specimens from supraclavicular lymph nodes. Intensive systemic survey demonstrated no other primary site than the lung. The patient was treated with cisplatin, adriamycin and etoposide and his subjective symptoms such as cough and dyspnea significantly improved over the next three months. Tumor shadows in the lung increased steadily, however after February, 1989. A significant lymphangitic spread of the carcinoma and marked obsteoblastic bone metastases were revealed at autopsy.

A 41-year-old male visited with chief complaints of chest pain and cough. The patient was operated on under a diagnosis of invasive thymoma. The tumor was located in the left lobe of the thymus and measured 6 X 9 cm. Since the tumor invaded the left innominate vein, pericardium, and the upper lobe of the left lung, we resected it with adjacent structures. Postoperative pathological examination indicated squamous cell carcinoma of the thymus. Because the tumor metastasized also to the mediastinal lymph nodes, the patient was treated postoperatively by radiation therapy and adjuvant chemotherapy mainly with CDDP. The patient is well presently 2 years after operation without signs of recurrence.

A 44-year-old woman was hospitalized for nonproductive cough. Chest roentogenogram revealed a calcified nodular mass at the right hilum. The patient was treated as tuberculosis of the hilar lymph node, however, her symptoms exacerbated within a year. A tumor obstructing the right main stem bronchus was demonstrated on bronchofiberscopic examination. Thoracotomy was carried out and tumor was diagnosed as primary osteogenic sarcoma of the pulmonary artery by pathological examination of the resected specimen. There was no clinical finding of osteogenic sarcoma throughout the bones.

A case of 51-year-old woman, she was suffered from primary parotic cancer and the right parotic gland was resected in 1980, and pulmonary metastatic nodule was also operated in 1982. She was admitted in our institute with complaint of bloody sputum and cough in 1989, and diagnosed as pulmonary and splenic metastasis of parotic cancer. Two courses of combined chemotherapy, with CDDP by administration through bronchial artery, with CDDP and VDS by a systematic intravenous injection, was done. With these therapies, partial responses were obtained in the metastatic lesions, so spleen and left lower lobe of lung were resected. In the histological examination of the resected tumors, tumor cells were nearly disappeared, and we obtained Ef-2 effect according to the general rule for clinical and pathological record of lung cancer. She was discharged after one more chemotherapy and with no sign of recurrence now. We reported this case because of the possibility of the effective adjuvant therapy of the case with multiple lesions of cancer metastasis, and the rare case of splenic metastasis.

We studied 8 adult patients with variable symptoms of cough, dyspnea, stridor, wheezing, or hemoptysis. Fiberoptic bronchoscopy in all showed complete or nearly complete endobronchial obstruction of a main-stem bronchus by neoplasm with a mean bronchial diameter of 1.9 mm +/- 1.6 mm (mean +/- standard deviation). In 4 patients, a lobar bronchus was also completely obstructed. No mass was visible on chest radiographs of any patient; however, computed tomography in each showed main-stem endobronchial obstruction, lobar obstruction (4 instances in 3 patients), and in 6 patients hypoperfusion of the involved lung. Computed tomographic scan showed additional abnormalities that were unsuspected on viewing chest radiographs or at bronchoscopy, including mediastinal adenopathy in 3 patients and an extraluminal tumor component in 4. After therapy with Nd-YAG laser, main-stem airway diameter increased to a mean of 9.6 mm +/- 1.0 mm (P less than .05) and pulmonary functions improved. Results suggest the complementary role of computed tomography and fiberoptic bronchoscopy in the detection and laser-treatment planning of chest radiographically occult severe neoplastic obstruction of the main-stem bronchus.

Malignant thymomas are extremely rare in children, with only 27 cases reported thus far in the pediatric surgical literature. We report four additional cases diagnosed at this institution over the past 20 years (ages 3 to 14 years). Clinical presentations included superior vena cava syndrome, cough, dyspnea, cyanosis, enlarging mediastinal mass, spontaneous pneumothorax, and pleuropericardial effusion. Three patients underwent incomplete resection of the mass or biopsy because of "unresectability" and were treated with radiotherapy and adjunctive chemotherapy. One patient underwent near complete macroscopic resection as well as radiotherapy and chemotherapy. All patients died at intervals ranging from 6 months to 2 1/2 years after diagnosis. Three patients were found to have metastatic disease prior to death or at autopsy. In one case, the initial pathological diagnosis was lymphocytic thymoma. After ultrastructural studies were performed, the diagnosis was changed to thymic T-cell lymphoma. This patient subsequently developed acute lymphoblastic leukemia 3 months after surgical resection followed by radiotherapy. Malignant thymomas are highly aggressive tumors in children. A radical surgical approach with complete excision of the tumor and contiguous structures in continuity, with adjunctive radiotherapy and chemotherapy remains the only hope for survival in children with these rare lesions.

A 74-year-old man complained of a cough and left chest pain. Chest X-ray showed marked pleural effusion and a large mass in the left lower lobe, and air bronchograms within the mass were observed by tomography and computed tomography (CT). About 3 months later, the patient died of left atelectasis and pneumonia. Autopsy revealed a localized tumor in the lower lobe of the left lung. Histologically, proliferation of lymphoma cells was noted. Immunoglobulin staining showed B cell-type monoclonality. No metastasis was evident except for a very small nodular area in the left renal cortex.

Thirteen cases of primary thymic carcinomas are described. The patients' ages ranged from 19 to 64 years, with a median of 40 years. Nine of them were male. Chest pain with or without cough was the main presenting symptom. No patient had myasthenia gravis. Five histological types were identified; two were undifferentiated (lymphoepithelioma-like) carcinoma, one was a clear-cell carcinoma, two were mixed squamous and small-cell carcinoma, and six were squamous cell carcinoma. All the tumors were variably positive for anti-keratin antibody AE1 and AE3, but negative for AE2. Anti-neuron specific enolase antibody was useful in identifying and confirming the small-cell carcinoma component of the mixed carcinomas. Anti-epithelial membrane antigen antibody aided in revealing the glandular structures in mixed adenosquamous and small-cell carcinomas. Thymic carcinomas were histopathologically differentiated from thymomas by their malignant cytological appearance, increased mitotic activity, and central tumor necrosis. All six patients with pure squamous-cell carcinoma were still alive, with a median survival time of 27 months. All but one of the other patients of different histological types died, the exception being a recent case of mixed adenosquamous and small-cell carcinoma; their median survival was 19.5 months, or 18 months when the latter surviving case is included. The prognosis of patients with pure squamous-cell carcinoma was better.

Reports is the case of a 21-year-old student, who received a medical examination at our Department for an abnormal chest shadow that had been detected during a periodic health examination at his university. No special subjective symptoms such as a cough and/or sputa, pyrexia, pectoralgia, and dyspnea were noted. A thyroid tumor was palpable and a 99mTc thyroid scintigram and a 201Tl thyroid tumor scintigram gave cause to suspect thyroid cancer and a metastatic lung tumor. A total thyroidectomy and a right modified neck dissection revealed a tumor (histologically, a papillary cancer), 3.5 cm in diameter, that mainly involved the right lobe. It was found that 131I-100 mCi internal irradiation was very effective for the metastatic lung tumor, and no abnormal shadow was subsequently revealed by chest X-ray. Now, 6 years later, he is alive with no manifestations of a local relapse nor any abnormal chest X-ray findings.

In this review the histological and clinical features of 12 endobronchial hamartomas seen between 1960 and 1987 are presented. All patients were men; the mean age was 54.0 years. Nine patients presented with pulmonary symptoms, most frequently cough. All lobes were affected, with a slight preponderance in the left upper lobe. Surgical treatment was given to 10 patients. In the other 2 cases bronchoscopic resection was preferable. There were no complications due to therapy. No recurrences were noted. This lesion should be regarded as a true neoplasm, in view of the clinical and histopathological characteristics.
