Positron emission tomography (PET) scan showed aortocaval lymphadenopathy. The diagnosis of follicular lymphoma grade 2 stage IV is made.Lymphoid aggregates appear as slightly elevated nodules that may be normal in color or more red than the surrounding tissue. Sometimes they can look like small polyps. This is a harmless, non- cancerous condition. Lymphoid aggregates occur when the normal lymphoid tissue collects in a certain location.The eLTs were discovered in the majority of grade 2 (64.29%) and 3 (92.31%) lymphoid aggregates but absent in grade 1 lymphoid aggregates . The eLTs presented more frequently in eosinophilic (20.69%) and noneosinophilic (17.31%) NPs compared with control subjects (3.70%, Fig 2).A lymphoid aggregate was defined as accumulation of lymphocytes and plasma cells without a germinal center. The lymphoid follicles and aggregates were categorized in 3 groups: (1) sub-epithelial small, present just below the epithelium and occupying half or less of the lamina propria; (2) basal small, present just above the …Clinically, depending on the extent of involvement, benign pharyngeal lymphoid hyperplasia may cause symptoms of nasal obstruction, Eustachian tube dysfunction, globus, dysphagia and obstructive sleep apnoea.
