Abstract

We report 22 cases of Hodgkin lymphoma involving Waldeyer ring seen at our institution during a 31-year interval. There were 16 males (73%) and 6 females (27%) with a median age of 48 years (range, 5–81 years), and 15 (68%) patients had airway obstruction or tonsillar enlargement. For 19 patients, the clinical stage was as follows: I, 7 (32%); II, 11 (50%); and III, 1 (5%). The 3 patients (14%) whose disease was unstaged had concurrent or a history of non-Hodgkin lymphoma. Histologically, the neoplasms were classified as follows: lymphocyte-rich classical, 8 (36%); nodular sclerosis, 7 (32%); mixed cellularity, 4 (18%); unclassified, 2 (9%); and lymphocyte depletion, 1 (5%). Of 7 stage I cases, 4 (57%) were the lymphocyte-rich classical type. Reed-Sternberg and Hodgkin cells were positive for CD15 and CD30 in 20 cases assessed. Epstein-Barr virus latent membrane protein type 1 was positive in 12 (67%) of 18 cases assessed. We conclude that Hodgkin lymphoma rarely involves Waldeyer ring, with the lymphocyte-rich classical type being common at this location.
