A 65-year-old man complaining of a left medial ocular angle mass and hemoptysis was admitted to our hospital. Chest radiography revealed a right hilar mass and bronchoscopy revealed widespread cancerous invasion of the carina, both main bronchi, right upper lobe bronchus, truncus intermedius, and middle lobe bronchus. Histological examination of a biopsied specimen revealed small cell carcinoma. Brain CT scan, abdominal CT scan, and bone scintigram showed solitary brain, multiple liver, and multiple bone metastases. Partial response was obtained with three courses of combined chemotherapy with carboplatin and etoposide, and the ocular tumor until it was almost invisible to the unaided eye. However, complete response could not be obtained with additional two courses of combined chemotherapy, and the patient was discharged. Seven months after the first admission, he was readmitted with dyspnea and an enlarged (6 mm in diameter) left ocular mass. Histological examination of the resected mass revealed a small cell carcinoma that had metastasized to the conjunctival substantia propria. He died of respiratory failure one month after readmission. Metastasis to the eye from primary lung cancer is uncommon and patients such as this are extremely rare. Although some cases of uveal or orbital metastasis from lung cancer have been reported, we can find no other report of conjunctival metastasis from lung cancer.

Well-differentiated thyroid carcinoma infrequently invades the upper aerodigestive tract. However, when invasion occurs, it is the source of significant morbidity. The most common structures invaded by thyroid carcinoma are the recurrent laryngeal nerves, larynx, pharynx, and esophagus. Invasion of these structures produces symptoms of airway insufficiency, dysphagia, and hemoptysis. This study was designed to define more clearly the significance of invasion of papillary thyroid carcinoma on survival. At the Mayo Clinic, 262 patients treated for invasive papillary thyroid carcinoma between 1940 and 1990 were retrospectively evaluated. In this group the sites of invasion were muscle 53%, trachea 37%, laryngeal nerve 47%, esophagus 21%, larynx 12%, and other sites 30%. Complete tumor removal was accomplished in 56% of cases. Kaplan-Meier survival curves were calculated for the population. The overall survival was 79% at 5 years, 63% at 10 years, and 54% at 15 years. When the Cox proportional hazard model was applied to the survival data, the factors that had significant influence on survival were invasion of the trachea and the esophagus. Completeness of resection approached statistical significance. Muscle invasion, laryngeal invasion, and recurrent laryngeal nerve invasion had no significant independent influence on survival. These data suggest that when papillary thyroid carcinoma extends beyond the thyroid capsule and invades adjacent structures, the site invaded will influence survival. Survival may be improved in those cases in which complete surgical excision of the tumor is performed.

We describe an occurrence of small cell carcinoma of the lung in a 37-year-old woman with rheumatoid arthritis who did not receive any kind of cytotoxic agents for the rheumatic condition. There seemed to have no predisposing factor for the development of malignancy. The diagnosis of small cell carcinoma was based on repeated hemoptysis and cytologic finding of a rapidly growing mass over the forehead. The patient responded dramatically to chemotherapy with rapid resolution of forehead mass, relief of arthritis in the hands, and decrease of serum rheumatoid factor from 4800U/ml to 1200U/ml. This appeared to be the first report of small cell carcinoma of the lung developing in a patient with rheumatoid arthritis.

Primary microcytic tumors of the trachea are very rare. Among them, primary microcytic carcinoma of the trachea has been described very few times. We present the case of a 44-year-old man with hemoptysis and asthenia, in which the thoracic radiography was normal. However, the bronchofibroscopy detected a microcytic carcinoma localized at the distal third of the trachea with adenopathies and hepatic metastasis. Complete remission was achieved with chemotherapy, remaining the patient free from the disease 10 months after the diagnosis.

Nine children (6 boys, 3 girls) were diagnosed with a primary endobronchial or pulmonary parenchymal neoplasm. The average age at diagnosis was 9 years. Presenting complaints included cough (7), fever (5), pulmonary infection (3), respiratory distress (3), weight loss (2), pain (2), and hemoptysis (1). Pulmonary x-rays showed persistent atelectasis, pneumonic infiltrates or mass lesions. A computed tomography scan was performed in 8. Five of six endobronchial tumors were diagnosed with bronchoscopy and biopsy. Treatment consisted of thoracotomy and pulmonary resection in 7 cases and laser resection in 2. The pathologic diagnoses were bronchial carcinoid (3), bronchial mucoepidermoid carcinoma (1), inflammatory pseudotumor (plasma cell granuloma) of the bronchus (2) and of the lung parenchyma (1), fibrosarcoma (1), and rhabdomyosarcoma (1). Postoperative chemotherapy was given only to the patient with pulmonary rhabdomyosarcoma; this child died. One child has developed a local recurrence while 7 children are alive and free of disease at an average of 2.4 years postresection. Pulmonary neoplasms are unusual in the pediatric age group and represent a wide spectrum of pathology. Including the present series, 383 tumors have been described. Seventy-six percent were malignant. Early investigation and surgical intervention are essential in children with persistent pulmonary symptoms or x-ray abnormalities. In most cases, the prognosis is excellent with complete surgical resection; however, malignancies other than bronchial adenoma are associated with significantly mortality.

A case of a 50-year male patient is presented. A cause of hemoptysis lasting for several months could not be identified in this patient. Chest X-ray and laboratory tests were normal. Temporarily atypical tubercle (Mycobacterium scrofulaceum) were seen in sputum, making proper diagnosis difficult. Further follow-up suggested cancer of the left lung. The diagnosis was ultimately confirmed intraoperatively. Histologically exceptionally malignant cancer--mucoepidermoid carcinoma--was diagnosed.

From 1977 to 1992, 23 patients with primary tumors of the trachea were reviewed. Nineteen of these patients had squamous cell carcinomas, 2 had adenoid cystic carcinomas, 1 had a small cell carcinoma, 1 had a poorly differentiated carcinoma, and 1 had a pleomorphic adenoma. The prognosis of squamous cell, small cell and poorly differentiated carcinomas appeared to be grave, especially in association with vocal cord palsy (26%). Short-term survival occurred in 7 to 9 patients with tumors in the upper-middle third of trachea and 4 of them had concurrent acute respiratory distress. Cough (65.2%), dyspnea (91.3%), and hemoptysis (47.8%) were the most common symptoms. For patients with hoarseness, dysphagia, and cervical lymphadenopathy, the prognosis was poor (p < 0.0010). Two patients (8.7%) had multiple malignancies and all died within 1 year. Smoking was not only a risk factor as reported in previous studies, but also a significant prognostic factor (p = 0.0020) in our series. Emergent irradiation ( < 40 Gy in our cases) was useful in alleviating acute respiratory distress, but worthwhile survival was only obtained by the combination of surgery and radiation therapy (p = 0.0200, compared with surgery or irradiation, respectively). There was a significant correlation between prognosis and histologic type, tumor location, clinical presentation, smoking history and management, but not roentography or tumor size. These factors can be used to assess the survival of patients with primary tracheal tumors.

One hundred eighty-eight patients with 191 lung cancers were collected retrospectively to evaluate the diagnostic results and to determine the accuracy of cytologic diagnoses obtained from ultrasound-guided fine-needle aspiration biopsy (US-guided FNAB), and to discuss the necessity of large-bore tissue core needle biopsy. All 188 patients underwent US-guided FNAB, and 20 patients with 21 lung tumors also underwent US-guided tissue-core needle biopsy. Using US-guided FNAB alone, the positive cytologic results and correct cytologic diagnoses were 91% (174 of 191) and 71% (37 of 52). If both US-guided FNAB and selected US-guided tissue core needle biopsy (n = 21) were evaluated, the positive cytologic or histologic results and correct cytologic or histologic diagnoses were 94% (180 of 191) and 80% (45 of 57), respectively. Analyzing the disagreement between the cytologic results and histologic diagnoses (n = 15), we found that the disagreement usually occurred in the specimens with poorly differentiated carcinomas (nonspecific cell type) (53% [8 of 15]); of these, two patients (13% [2 of 15], small cell carcinoma) would have a change in treatment. The complications of US-guided FNAB were pneumothorax (n = 3), hemoptysis (n = 1), hemothorax (n = 1), and suspected tract metastasis (n = 1). We conclude that US-guided FNAB has a high diagnostic yield in lung cancers, and US-guided tissue core needle biopsy is only necessary in patients whose cytologic results are negative or who have poorly differentiated carcinomas.

A 70-year-old man was admitted to the hospital because of mild dyspnea, a cough, and hemoptysis. A chest X-ray film and a computed tomographic scan showed a mass in the S1.2 region of the left lung, and swollen mediastinal lymph noes. Cytologic examination of sputum sample resulted in the diagnosis of lung cancer. The tumor did not respond to chemotherapy, and the patient died after seven months. Autopsy disclosed a solid tumor of left lung and many cystic lesions in the liver. Histological examination of the lung lesion revealed adenosquamous cell carcinoma. Metastatic lesions in the liver consisted of adenosquamous cell carcinoma, with predominantly squamous cell carcinoma. Cases of lung cancer in which hepatic metastases have many cystic cavities are rare.

Lung cancer is the most common malignant cancer in males and it's incidence is rapidly rising in females. Factors linked to this are associated with cigarette smoking, urbanization along with atmospheric pollution. The lack of success in the treatment of lung cancer has to do with in many cases late diagnosis at the stage when surgical treatment is not possible and radio and chemotherapy being of minimal effectiveness. The WHO has proposed the following classification of lung cancer: 1. Squamous cell carcinoma; 2. Small cell carcinoma; 3. Adenocarcinoma; 4. Giant cell carcinoma; 5. Adeno-squamous cell carcinoma 6. Carcinoid. 7. Carcinoma of mucous gland. 8. Others. Early physical signs of lung cancer are: cough (50-80% of patients), dyspnea (10-15%), chest pain (15-20%), hemoptysis (20-50%), recurrent pneumonia and bronchitis (30-50%). More serious clinical signs associated with growth of the neoplasm are hoarseness, pleural effusion, vena cava superior syndrome, and Pancoast's syndrome. The growing neoplasm secrets many biochemical substances, which are them activity passed on the bloodstream or make their way into the blood as a result of degeneration of the tumor. These substances may then be detected in the patient's plasma and act as markers of malignant disease. The characteristics of these markers is varied, e.g.: hormones, enzymes and tissue antigens. Methods used in the diagnosis of lung-cancer which should be stressed, are apart from the obvious physical examination are chest x-rays, ultrasound, CAT scans, nuclear magnetic resonance, PET scans, and scintigraphy. Fine needle aspiration in changes in the peripheral regions, cytology of sputum, bronchial lavage, cytogenetic analysis. This underlines the need for prophylaxis, particularly the cessation of cigarette smoking.
