[Malignant non-Hodgkin's lymphomas in abdominal surgery: apropos 3 cases of Burkitt's lymphoma].

On the occasion of three observations of the extremely rare and malignant Burkitt's lymphoma, the authors record their 7-year experience in the operative treatment of 22 patients with non-Hodgkin's malignant lymphomas. Proceeding also from data available in the current literature, the most frequently encountered syndrome-complex is presented, the knowledge of which is of major importance for the early diagnosis, resp. for the results of combined treatment. The possibilities of the operative treatment are evaluated. In the authors' series it was radical in 31.8 per cent of the cases with 13.6 per cent early postoperative lethal outcome and 5.2 months average postoperative survival rate. Proceeding for the rarity of the disease in everyday surgical practice and that it is poorly known, but has become a nosologic entity of increasing interest, the authors have devoted the first part of their article to a discussion on the basic characteristics of non-Hodgkin's malignant lymphomas and the modern achievements of their treatment.
