Abstract
The abdomen, particularly the ileocecal region, is the most commonly affected disease site in sporadic Burkitt lymphoma (BL). Involvement of the stomach is very rare. Primary gastric atypical Burkitt lymphoma has not been described in the literature, to the best of our knowledge. In this case report, we discuss a patient with atypical Burkitt lymphoma involving the stomach. The immunohistochemical stains showed positive results for CD20, PAX5, BCL6, CD10, and high ki-67. The fluorescence in situ hybridization (FISH) test revealed a positive result for c-MYC gene rearrangement, but there was no evidence of the typical translocation associated with Burkitt lymphoma involving the IgH, kappa, or lambda genes.
