[Clinical experience with 16 cases of mediastinal lymphoma].

Sixteen cases of mediastinal lymphoma in our hospital were reviewed clinically. There were 7 men and 9 women, whose mean age is 35 years old. The histological types were non-Hodgkins' disease in 12 (B-cell type in 6 and T-cell type in 6), Hodgkins' disease in 2, mucosa-associated lymphoid tissue (MALT) lymphoma in 2. All cases except 1 in which percutaneous needle biopsy was performed were diagnosed histologically. Even small specimens by percutaneous needle biopsy can be helpful in diagnosing histological type and subtype with immunohistlogy, recommending percutaneous needle biopsy as an mitial step for diagnosis. When histological diagnosis can not be made by needle biopsy, open biopsy should be done.
