ABSTRACT
Background and study

aims:

The gastrointestinal (GI) tract is the most common site of extra-nodal involvement for non-Hodgkin's lymphoma (NHL). The features of GI NHLs remain unclear. The aim of this study was to clarify endoscopic characteristics of GI NHLs. Patients and

methods:

We retrospectively analyzed the morphological characteristics of 63 GI malignant lymphomas other than mucosa-associated lymphoid tissue lymphoma. Lesions were diagnosed between 2005 and 2020. Macroscopic findings were classified into five subtypes superficial (S); protruding without ulcer (P); protruding with ulcer (PU); fungating (F); and multiple nodules (MN).

Results:

Thirty-one lesions in the stomach were classified as S type in 3 cases (9.6%), P type in 6 (19%), PU type in 13 (42%), and F type in 9 (29%). In the stomach, the ulcerated phenotype was more frequent for diffuse large B-cell lymphoma (DLBCL) (89.5%) than for other histological types (41.7%; P = 0.01). In the intestine, 23 tumors were classified as S type in 4 cases (17%), P type in 1 (4%), PU type in 6 (26%), F type in 1 (4%), and MN in 11 (48%). Eleven of the 14 cases (78.6%) of intestinal follicular lymphoma lesions showed MN type. In the colon, eight tumors were classified as S type in 2 cases (25%), P type in 2 (25%), PU type in 1 (13%), and F type in 3 (38%).

Conclusion:

We have clarified the endoscopic features of GI NHL using macroscopic classifications. The ulcerated phenotype was the most frequent endoscopic finding for DLBCL.
