[Primary choriocarcinoma of the liver in a 36-year-old male patient. A case report and literature review].

The article presents a case of primary liver choriocarcinoma in a 36-year-old man. The patient was admitted to the hospital with signs of rapidly developing multiple organ failure, in connection with which the diagnosis was verified at autopsy according to histological and immunohistochemical studies. Diagnostic criteria and treatment options for this disease are insufficiently developed due to its rarity.

[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.
