Abstract

Lymphoepithelial cyst (LEC) is the most commonly encountered congenital neck pathology in the lateral part of the neck. A 66-year-old woman presented to the ENT clinic due to difficulty in swallowing persisting for approximately 1 year. Magnetic resonance imaging revealed a cystic mass at right tonsil. Surgery was performed due to this unilateral tonsillar mass, which was excised together with the right tonsil. LEC was diagnosed at histopathological examination. LEC in the palatine tonsil is rare, and only a few cases have been reported in the literature. We report a rare case of LEC in the palatine tonsil.

A cystic mass (black arrow) hypointense on T1 images and hyperintense on T2 was observed inside the right tonsil at magnetic resonance imaging (MRI).

Figure 2
The cyst wall was lined with a stratified squamous epithelium surrounding the stroma consisting of lymphoid follicle structures with germinal centers. Fibroconnective tissue, adipose tissue, vascular structures, seromucous glands, and muscle tissue at the most external part were also observed in the stroma (H&E ×20).
