[Bronchiolitis obliterans organizing pneumonia: survey based on two cases].

Authors offer a survey about an aspect forming a clinical entity called bronchiolitis obliterans organizing pneumonia, by two of their patients' presentation. In Case 1 the process manifested in form of a disseminated, small spotted, diffuse shadow, causing serious resting hypoxia. Diagnosis was supported by histological examination of a substance obtained by small surgical thoracotomy.

The Clinical Significance of the Primary Malignant Melanoma of the Lower Respiratory Tract and/or Lung Based on the Analysis of Published Case Reports and of Two Patients.

Considering the data and including two patients of the authors, there exist only 18 authentic cases of primary malignant melanoma of the lower respiratory tract and/or the lung. The tumor was localized in the endobronchial space in 7 cases and only once in the trachea. Endobronchial localization, together with the involvement of the surrounding lung tissue, was found in two cases, whereas in 8 patients, the tumor was found exclusively in the lung parenchyma.

[Primary malignant melanoma of the lung and lower respiratory tract].

After detailed analysis of the international special literature, the authors found--together with their own two patients--only 18 cases, considered primer malignant melanoma of the lower respiratory tract and/or lung. Of the accepted criteria, they dispute the obduction's absolute evidentiary role, because among primer patients there are the most who survives, even a decade. In seven cases tumour was located endobronchially and in one patient in the trachea.
