Three cases illustrate the principal clinical and roentgenographic varieties of granular cell myoblastoma (GCM) of the lung. The vast majority are small benign intrabronchial tumors without roentgenographic findings. These remain asymptomatic and are detected accidentally at autopsy, surgery, or bronchoscopy (Case III). Larger obstructing lesions (Case I) cause focal atelectasis or pneumonitis, leading to cough, expectoration, and hemoptysis. Hilar enlargement from reactive lymph node hyperplasia is common. Clinically and roentgenographically these are indistinguishable from bronchial adenomas. Least often the tumor extends entirely extrabronchially (Case II) presenting as a parahilar parenchymal asymptomatic nodule, simulating a granuloma, hamartoma, arteriovenous malformation or a neoplastic nodule.

YAG laser treatment was conducted in 55 patients with central airway lesions over the last 8 years. The malignant lesions comprised 1 primary tracheal cancer, 1 chondroma of the trachea, 34 primary lung cancer, and 10 metastatic lung tumor. The benign lesions comprised one each of hamartoma, lipoma, bronchial lithiasis, post-tracheotomy granuloma, and bronchial web, and 3 other cases. Nd-YAG laser treatment was performed in 55 patients with airway lesions, with a success rate of 73%. The success rates in the above patients were 70% for primary lung cancer, 60% for metastatic lung tumor, 100% for primary tracheal cancer and chondroma of trachea, and 89% for benign lesions. In 34 patients with primary lung cancer, palliative widening of the airway was planned with the exception of 2 patients with endoscopically early lung cancer for whom curative vaporization was intended, 6 months-survival rate was 59.3% in patients in whom various combined treatments were performed after the laser treatment. For all patients with hamartoma or lipoma in those with benign lesions, curative vaporization was performed. The severe complication of lethal massive hemoptysis occurred in 3 patients. We consider that Nd-YAG laser treatment is a powerful therapeutic means of performing lifesaving or emergency, curative, and supplemental treatment.

Chondroid hamartomas disseminated in both lung fields were discovered in a 76 year old man presenting with recurrent haemoptysis. In view of this metastatic cannonball appearance and the negative investigations, exploratory thoracotomy was performed, revealing the correct diagnosis. Although classical, this form of hamartoma is rare and warrants a case report.

Pulmonary lymphangioleiomyomatosis (p.l.) is a rare disease of unknown etiology, and restricted to fertile women. It is characterized by a nodular proliferation of smooth muscle cells in the peribronchial, perivascular and perilymphatic lung tissue, accompanied by cystic dilations of the alveoles, rupture of the alveolar wall, lymphangiectasis, and septal collagen fiber deposition. Radiological-alterations range from enhanced interstitial shadowing to honey comb lung. Common clinical symptoms are progressive dyspnea, pneumothorax, chylous pleural effusion and hemoptysis. Here we present the case of a 43 years old woman, undergoing nephrectomy because of hamartoma of the left kidney, with recurrent pneumothorax and progressive dyspnea, verifying the diagnosis of p.l. by open lung biopsy. Pathogenesis of the disease, differential diagnosis and possible therapeutic approaches are discussed.

The authors analysed 116 hospitalized patients who, in their routine cytologic examination of the sputum, had also a cytomorphologic finding of lymphocytes. The greatest majority of these patients, 63 of them or 54.3% suffered from malignant neoplasm. Out of these 63 patients, 53 of them or 45.7% suffered from primary bronchial carcinoma, whereas 10 patients or 8.6% had non-Hodgkin's lymphoma, metastatic lung cancer of extrathoracic primary localization, Hodgkin's lymphoma, while two patients were supposed to have lung neoplasm. Our study also revealed that 14 patients (out of 116 hospitalized patients) or 12.0% suffered from broncho-pleuropneumonia, 13 or 11.2% from an active pulmonary tuberculosis, 7 or 6.0% from a chronic obstructive bronchitis, 5.1% from sarcoidosis, 3.4% from post tuberculosis pulmonary changes while 2.5% of the patients were found to have a pleural empyema. One case of bronchial asthma, tuberculous pleurisy, bronchiectasis, hamartoma, hemoptysis and a pulmonary infarction were found as well. Due to their own experience the authors conclude that the lymphocytes in the sputum were found to be the most frequent in patients suffering from primary bronchial carcinoma, broncho-pleuropneumonia and pulmonary tuberculosis but that they could also be found in many others pathologic changes of pulmonary parenchyma.

Mesenchymal hamartomatous nodules and cysts in the lungs caused hemoptysis, pneumothorax, hemothorax, pleuritic chest pain, dyspnea of slight or moderate degree, or a combination of these signs and symptoms in five patients. In four cases the disease was multifocal and bilateral. The nodules were composed of primitive mesenchymal cells subdivided into papillae by a plexus of small airways lined with respiratory epithelium. The nodules grew slowly in number and size over the years and apparently became cystic when they reached a diameter of about 1 cm. The cysts had a cambium layer of mesenchymal cells and were lined with normal or metaplastic respiratory epithelium. In general, the disease had an indolent course. The most serious complications were sudden hemorrhage into a cyst from large systemic arteries supplying the walls of the cysts, pneumothorax or hemothorax from rupture of a subpleural cyst, and malignant transformation in one case. This disease appears to represent a distinct clinicopathological entity, which I term mesenchymal cystic hamartoma of the lung.

A patient with a rare cystic hamartoma of the lung had diagnoses of tuberculosis, bronchiectasis, pneumonia, and neoplasm during the 23 years prior to resection of the lesion. The hamartoma had vascular elements which led to intermittent hemoptysis and, finally, to gross hemorrhage into the lung.

Hamartoma is one of the most common benign tumors in the lung, and most of the lung hamartomas are located in the parenchyma. This report reviews 24 cases with this kind of tumor. The male-female ratio was 1.4:1 and the mean age 46.4 years. Sixteen patients of the 24 were asymptomatic, while in the remainder cases chest pain or distress, cough, short breath or hemoptysis were presented. Lung hamartoma is usually composed of cartilage, fat, smooth muscle and respiratory epithelium. X-ray findings of the parenchymal type in these cases were characterized by a round or oval sharply outlined mass, but only one with a mass in the shape of a dumbbell. 33% cases showed calcification. In 19 cases the mass was < 3.0 cm diameter (79%) and in 17 it was located in the superficial edge of the lung. The diagnosis was confirmed in only 6 cases preoperatively. The other cases were misdiagnosed as lung cancer, tuberculoma, metastatic tumors of the lung, etc. Enucleation or wedge resection is desirable for this kind of tumor.

A 53 year old man presented with massive haemoptysis, and chest radiography revealed a left suprahilar mass. At thoracotomy he was found to have a modular mass in the left upper lobe, which was attached to a peripheral bronchus. Histology confirmed a pulmonary hamartoma.
