OBJECTIVE: To study the relationship between the lymphoid follicles in mucous membrane of pharynx and mucosal associated lymphoid tissues (MALT). METHOD: Ten folliculi obtained from 10 patients of follicular pharyngitis and mucosa taken form 10 patients of paranasal sinusitis were fixed in neutral formalin and embedded in paraffin. Sections were prepared, stained by H. E and by immunohistochemical method staining with S-100,and observe by light microscopy. We observed the morphology of lymphoid follicles in mucous membrane of pharynx with MALT in mucosa of paranasal sinusitis as the contrast. RESULT: Lymphoid follicles in mucosa of pharynx compared with MALT in the mucosa of paranasal sinuses, there was no mantle zone, no typical germinal center and no mucosal epithelium, immunological staining with S-100 was week. CONCLUSION The lymphoid follicles in mucosa of pharynx does not belong to the MALT.
