[Clinicomorphological observation of bronchioloalveolar carcinoma of the lung].

The authors analyze rare lung diseases and describe a clinicomorphological case of bronioloalveolar carcinoma of the lung as one of rare bronchopulmonary diseases. According to the WHO histological classification (1999), the tumor is adenocarcinoma that is represented solely by bronchioloalveolar vegetations as a monolayer of the cells lining the walls of pre-existing alveoles without invasion of the stroma, vessels, and pleura. In 1876 Mallaser first described this rare disease in cloven-hoofed animals (Artiodactyla) in Scandinavian countries. Subsequently cases of this disease were also described in human beings.
