Abstract
BACKGROUND: Extranodal lymphomas occurring in the head and neck region account for 12-15% of all malignant tumors of this locality. Classical Hodgkin lymphoma (cHL) is a rare subtype, representing around 1% of all lymphomas in Waldeyer's ring. Cases diagnosed in the Reference Centre for Lymph Node Pathology at the Pathological Institute of the University of Würzburg were further analyzed in this study. MATERIALS AND METHODS: Histological subtype and EBV association of 21 cases were reviewed in conjunction with clinical data. RESULTS: Data of 12 male and 9 female patients with an average age of 51 years (median 45; 35-72) were reviewed. All samples were taken from the lymphatic tissue of the Waldeyer's ring (nasopharynx n = 15, palatine tonsils n = 5, lingual tonsils n = 1). The most common symptoms leading to a consultation with an otorhinolaryngologist were otalgia, swelling, or impaired nasal breathing. Only four patients showed typical B‑symptoms. In 6 cases (29%), an isolated extranodal manifestation was found, 15 patients (71%) showed simultaneous infiltration of cervical lymph nodes during staging, and 6 cases (29%) were EBV positive. CONCLUSION: An exclusively extranodal manifestation of cHL in Waldeyer's ring is rare, whereas infiltration of extranodal tissue in the case of a primary manifestation of lymphoma in cervical nodes can occur more frequently and may often remain undiagnosed. Therefore, a specialized ENT consultation could be a reasonable complementary module in tumor staging to determine the correct tumor extent.
