[Difficulties and errors in diagnosis of intrathoracic adipose tumors].

The authors treated 9 patients with intrathoracic adipose tumors of rare localization. In 4 cases the lipoma arose from the thoracic wall, in 2 directly from the mediastinum, and in another 2 from the pericardium. Lipoma of the lung and, 6 years later, liposarcoma of the diaphragm were removed in one patient.

[Diagnostic difficulties and errors in neoplasms of the diaphragm].

During 1972-1990 twelve patients with tumors of the diaphragm were operated upon. Age of the patients was from 39 to 60 years. Nine patients had benign tumors and cysts, 3 patients had malignant tumors.
