Non-Hodgkin lymphoma (NHL) is a diverse group of lymphoid malignancies, with varied clinical presentations depending on the anatomical site of involvement. Although typically presenting with nodal disease, extranodal manifestations are not uncommon. NHL involving Waldeyer's ring is considered rare, with the palatine tonsils being the most frequently affected location. This case report presents a 30-year-old male patient with bilateral tonsillar hypertrophy, ultimately diagnosed as NHL. The patient presented with a persistent sore throat, dysphagia, and snoring associated with sleep disturbances. Detailed physical examination, imaging studies, and histopathological analysis of the excised tonsillar tissue confirmed the diagnosis. This case underscores the importance of considering NHL in the differential diagnosis of persistent tonsillar enlargement to ensure timely and appropriate management.
