Both cases were older men with stomach ulcers. Case 1 was admitted for a hemorrhage in the upper digestive tract and case 2 for edema. Histology of both cases showed infiltrated monomorphic and medium-sized lymphocytes with lymphoid epithelial phenomenon. An inflammatory background and vascular hyperplasia were also observed likely due to the ulceration. Neoplastic cells expressed CD2, CD3, CD7, CD8, CD56, TIA-1, and MYC, not CD5, CD4, Granzyme B, CD20, CD30, TdT, or EBER. Both lymphomas showed TCRG gene rearrangement and c-MYC gains. Moreover, we first affirmed polysomy of chromosome 8 in case 2. For correct diagnosis of this rare tumor at the rare location, it is important that pathologists raise the possibility and exclude other differential diagnoses.<\/jats:p>","DOI":"10.1177\/1066896920953906","type":"journal-article","created":{"date-parts":[[2020,8,28]],"date-time":"2020-08-28T07:26:10Z","timestamp":1598599570000},"page":"410-419","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":7,"title":["Monomorphic
