AbstractDetection of nasopharyngeal carcinoma primaries in patients presenting with neck node metastases may sometimes demand considerable efforts. By using the ‘ in situ hybridization’ technique, wemanage to identify the Epstein-Barr virus in neck metastases secondary to nasopharyngeal carcinomas. We propose that such identification in neck node metastases where the primary lesion is unknown indicates a nasopharyngeal primary.

AbstractTo define prognostic impact of Epstein-Barr virus (EBV) infection in diffuse large B-cell lymphoma (DLBCL), we investigated EBV status in patients with DLBCL. In all, 380 slides from paraffin-embedded tissue were available for analysis by EBV-encoded RNA-1 (EBER) in situ hybridization, and 34 cases (9.0%) were identified as EBER-positive. EBER positivity was significantly associated with age greater than 60 years (P = .005), more advanced stage (P < .001), more than one extranodal involvement (P = .009), higher International Prognostic Index (IPI) risk group (P = .015), presence of B symptom (P = .004), and poorer outcome to initial treatment (P = .006). The EBER+ patients with DLBCL demonstrated substantially poorer overall survival (EBER+ vs EBER− 35.8 months [95% confidence interval (CI), 0-114.1 months] vs not reached, P = .026) and progression-free survival (EBER+ vs EBER− 12.8 months [95% CI, 0-31.8 months] vs 35.8 months [95% CI, 0-114.1 months], respectively (P = .018). In nongerminal center B-cell–like subtype, EBER in situ hybridization positivity retained its statistical significance at the multivariate level (P = .045). Nongerminal center B-cell–like patients with DLBCL with EBER positivity showed substantially poorer overall survival with 2.9-fold (95% CI, 1.1-8.1) risk for death. Taken together, DLBCL patients with EBER in situ hybridization+ pursued more rapidly deteriorating clinical course with poorer treatment response, survival, and progression-free survival.

Abstract We report the autopsy case of a 34-year-old Japanese man with a nasal natural killer (NK)-cell/T-cell lymphoma. The patient developed the disease at 32 years of age, and a biopsy of the nasopharynx revealed pleomorphic lymphoma cell proliferation. Radiotherapy was performed, but the patient eventually died of respiratory failure. After radiotherapy, no histologic evidence of malignancy was obtained with biopsy materials featuring lymphocytic infiltration. Autopsy studies, including in situ hybridization for Epstein-Barr virus–encoded RNA, revealed generalized infiltration of normal lymphocyte-like, UCHL-1–positive, and Epstein-Barr virus–encoded RNA–positive lymphoma cells. Monoclonal proliferation of the Epstein-Barr virus–carrying cells was verified by means of Southern blot analysis. Retrospectively, we concluded that the normal lymphocyte-like presentation of the lymphoma cells, probably influenced by radiotherapy, prevented pathologists from recognizing the lymphoma. The utility of in situ hybridization for Epstein-Barr virus–encoded RNA in identification of tumor cells is emphasized with respect to the present case.
