[Clinical considerations on retroperitoneal liposarcoma. Report of 2 cases]. / Considerazioni cliniche sul liposarcoma retroperitoneale. Presentazione di due casi

Liposarcoma is one of the more common tumours of the soft retroperitoneal tissues. It usually occurs in aged subjects and displays a marked contrast between its malignant histological picture and its protracted, poorly symptomatic clinical picture. Eventually, compression or invasion of nearby organs appears, whereas the patient's general condition is not affected. Two personal cases are described.

[Case of pulmonary fibrosis with normal thoracic x-ray]. / Un caso di "fibrosi polmonare" con rx torace normale

Respiratory performance tests and the gas diffusion data sometimes clinch the diagnosis of lung disease when all other findings are negative. A subject with cyanosis, dyspnea, drumstick fingers, a normal chest X-ray picture and restrictive functional changes accompanied by inefficient diffusion is described.
