| Abstrakt: | Background: Classical Hodgkin lymphoma (CHL) is characterized by a proliferation of malignant cells of the lymphoreticular system and often involves lymph nodes, spleen, liver, and bone marrow; it is rare in the head and neck region. Case Description: A 58-year-old man had an enlargement with ulceration in the left palatine tonsil that was causing dysphagia. Microscopic examination revealed an infiltrate of large, atypical lymphoid cells positive for cluster of differentiation 30, cluster of differentiation 15, PAX5, and Epstein-Barr virus. Complementary tests initially ruled out other sites of the disease. The results led to diagnosis of a rare development of CHL in the palatine tonsil, which was staged as IIEB. Before therapy was initiated, nodal lesions developed in the neck and the CHL was restaged as IIB. The patient was treated successfully with a regimen of doxorubicin, bleomycin, vinblastine, and dacarbazine. After a review of the literature, the authors found only 3 cases with the clinical, imaging, and microscopic features of primary CHL of the palatine tonsil. Practical Implications: Despite being a rare event, CHL may first develop in extranodal sites, such as the palatine tonsil. In this context, the role of the dentist is pivotal for early diagnosis of the disease. Investigations into the development of primary tonsillar CHL in the oropharynx are needed because the disease has a different clinical course than nodal lesions.
