Classifying Gastrointestinal Lymphomas

Interobserver variation in classifying lymphomas among hematopathologists

BACKGROUND Lymphomas are common malignancies that have various subtypes with many overlapping histologic, immunophenotypic and genetic features. Therefore, discordance in classifying lymphoma among pathologists may be encountered. But this issue is not well characterized. We conducted the present study to demonstrate discordances among Thai hematopathologists as well as to highlight common argu...

Diagnosis of Primary Gastrointestinal Lymphomas and Mimics

Primary lymphomas of the gastrointestinal tract.

BACKGROUND A retrospective analysis of 12 years' experience (1987-1999), concerning gastro-intestinal lymphomas (LNH-GI) has been performed, to offer a contribution for the identification of the diagnostic and prognostic criteria. METHODS During this period, 11 cases (9 male and 2 female) have been treated: 8 with gastric localization and 3 with intestinal localization, with age ranging betwe...

The problem of classifying lymphomas: an orderly prescription for progress.

In the late 1960s and early 1970s, the most widely recognized 'new' classifications of the non-Hodgkin's lymphomas were those proposed by Rappaport (the 'Rappaport' classification) and by Lennert (the 'Kiel' classification). With the advent of immunologic and histochemical markers in the early 1970s, however, new concepts arose to supplement the traditional purely morphologic approach to diagno...
