Multiple small bowel perforations during the treatment of primary intestinal extranodal natural killer/T‐cell lymphoma, nasal type

Abstract

Fig 2. (A) Intestinal mucosa with an important lymphoid infiltrate in the submucosa (left). On the right side the mucosa has been replaced by lymphoid infiltrate (ulcer). We can observe that the infiltrate is transmural. (B) Heterogeneous and moderate membranous immunostaining for CD3 by lymph cells. (C) Lymph cells showing diffuse and intense CD56 positivity. (D) In situ hybridisation for Epstein-Barr virus (EBV)-encoded small RNA (EBER) demonstrates presence of EBV in several cells.
