Fiberoptic examination showed swelling of the lingual tonsil, epiglottic and arytenoid mucosa, causing airway obstruction (Fig. 1a). Her fiberoptic pharyngeal findings improved (Fig. 1).
Histological findings (a, b) showing granulomatous reaction in lingual tonsil with CD68 (Kp-1) positive epitheloid histiocytes by immunohistochemistry (c). Strong CD20-immunopositivity in B-lymphocytes (d). Most CD3-positive (e) T-lymphocytes showed also CD4-positivity (f)
