INTRODUCTION: A few patients with asymmetric palatine tonsils have lymphoma; but most lymphomas in palatine tonsils evolve with tonsillar asymmetry. OBJECTIVE: To report the profile of patients and histopathological changes in patients submitted to adenotonsillectomy/tonsillectomy with disproportional palatine tonsils. METHOD: Retrospective study based on data analysis from the Pathologic Anatomy Service Database and in the review of reports of patients submitted to adenotonsillectomy and tonsillectomy with palatine tonsils asymmetry during the period from October 1999 through October 2009 at the Clinical Hospital (HC) of the Federal University of Paraná (UFPR). RESULTS: 50 patients took part, aged between 3 to 53 years old, mean age of 14.05 years. The anatomopathological exam confirmed 48 patients (96%) with lymphoid hyperplasia and 2 cases of lymphoma (4%). These included men aged from 40 to 53 yeas with complaint of unilateral increase of the tonsil, one of whom had other symptoms (asthenia and weight loss). Upon physical examination: tonsils disproportion without involvement of other organs or lymph nodes. CONCLUSION: Our study is according to the literature as regards the fact the lymphomas are more common in men, the patient is the first one to notice the increase in volume and the asymmetry is larger than 2 degrees between palatine tonsils in cases of lymphoma. Although it is rare, even in the presence of differences, there are chances for the asymmetry to evolve to a malignant profile. The need for anatomopathological evaluation of a part must be considered along with other clinical data that suggests a malignant profile.
