[Lung carcinoma in patient with previously excised tuberculoma].

The paper presents a case of right lung carcinoma diagnosed 7 years after tuberculoma excision performed in the same lung. The diagnosis was based on observing the increase of a non suspicious mass. It is unclear whether the cancer developed from metaplasia, or was a primary tumor, mistaken for a tuberculoma.

[Chylothorax in patients with diffuse pulmonary lymphangiomatosis].

The occurence of chylothorax is uncommon and usually is caused by trauma or neoplastic process of the mediastinum. Primary lymphatic lesions of the lungs are extremly rare. One of them is lymphangiomatosis --diffuse lesions characterized primarily by an increased number of complex anastomosing lymphatic channels in which dilatation is secondary phenomenon.

[Recurrent pneumothorax as alone manifestation of mesothelioma pleurae].

Malignant mesothelioma of the pleura is a rare neoplasm with a poor prognosis. The most often symptoms of this disease are dyspnoe and chest wall pain, which is often associated with pleural effusion. We present 35-years old woman with 5 epizodes of pneumothorax during 3 years (4 of right side and 1-bilateral) in whom bilateral pleurodesis was performed.
