Abstract
AIM: To improve the diagnosis level of primary gastric lymphoma by observing the endoscopic patterns and analyzing the reasons of misdiagnosis.
METHODS: A total of 51 primary gastric lymphoma diagnosed by endoscopic biopsy and 27 pseudo-diagnosed “lymphoma” by endoscopy were included in this study. The endoscopic patterns of the two groups were compared and analyzed with Mann-Whitney U rank-sum test.
RESULTS: Primary gastric lymphomas were mainly ulcer type (33/51, 65%) and nodus type (12/51, 23.5%). The 27 suspected gastric lymphomas were mainly nodus type (13/27, 48%) and bulky mucosa type (10/27, 37%). There was significant difference between two groups in endoscopic patterns (P < 0.001). However, there was no significance in movements and texture (P > 0.05).
CONCLUSION: Endoscopic patterns of primary gastric lymphoma present polytypism. It is important for the avoidance of misdiagnosis to acquaint its endoscopic presentation and combine with deep and multi-spot biopsy.
Key Words: Primary gastric lymphoma; Endoscopic patterns; Misdiagnosis
