(D) In situ hybridisation for Epstein-Barr virus (EBV)-encoded small RNA (EBER) demonstrates presence of EBV in several cells. gl The patient had an uneventful postoperative period and was discharged to the Department of Haematology. According to that study, our present patient would probably have benefited from surgical treatment first, with resection of the affected intestinal areas followed by chemotherapeutic treatment, thus avoiding the perforations of the tumour-affected small bowel areas during chemotherapy treatment. Sometimes, patients with ENKTL-NT are only affected in extra-nasal sites, most frequently the skin, soft tissue, or as in the case of our present patient GI tract. [Extracted from the article]
