From: A case of iatrogenic immunodeficiency-associated colonic lymphoma complicating ulcerative colitis
Histological findings of the resected colon: a The resected colon is transmurally infiltrated by lymphoid cells, and the existing structure is indistinct. b Atypical polymorphous cells diffusely proliferate. c A few Hodgkin-like cells with an eosinophilic nucleolus in the center of a large nucleus are present. d A crypt abscess surrounded by mixed inflammatory cell infiltrates is present in the lamina propria mucosae remote from the lymphoma, compatible with the findings of UC
