Tumors lymphocytic infiltration has prognostic and predictive value. However, the mechanisms involved in lymphocyte recruitment remain poorly characterized. High endothelial venules (HEV) are blood vessels specialized in lymphocyte recruitment, recently showing prognostic significance in some types of cancer. Their implications in laryngeal or pharyngeal cancer is largely unknown. To investigate the possible presence of HEVs in head and neck cancer. Oropharyngeal (n = 61), hypopharyngeal (n = 53) and laryngeal (n = 21)
