Bilateral Symptomatic Cystic Lesions of the Palatine Tonsils Successfully Treated by Endoscopic Excision: A Rare Case Report.

Abstract

Cystic lesions of the palatine tonsils may occasionally be encountered in clinical practice, whereas bilateral involvement is exceptionally uncommon. We report the case of a 74-year-old man who presented with pharyngeal discomfort and bilateral cystic lesions in the inferior poles of the palatine tonsils. Endoscopic examination and radiological imaging revealed well-circumscribed cystic lesions without diffusion restriction. The lesions were excised endoscopically under general anesthesia, and histopathological examination revealed cyst walls lined by stratified squamous epithelium with underlying lymphoid tissue. The postoperative course was uneventful, and no recurrence was observed during the 1-year follow-up period.
