[Intestinal localizations of non-Hodgkin's lymphoma (clinical and histopathologic considerations)]

The authors describe two cases of malignant lymphoma localized in the rectum and caecum respectively and, taking into account the data reported in the literature, comment on current classifications and on the latest typing methods, particularly those based on radio-immunological assay. They stress the importance of a uniform clinical classification for diagnostic and therapeutic purposes as well as the increasing amount of interest in these neoplasms, especially in relation to those carcinomas where differential diagnosis does not always prove an easy matter.
