Two Cases of Extraparotid Warthin ’s Tumor in Lateral Cervical Region

Extraparotid Warthin’s tumor(EPWT) is a rare disease entity; its incidence is about 8% of Warthin’s tumor (WT). The periparotid and upper cervical lymph nodes are the most predilection sites. The lymphoid tissue of WT can act like a regional lymph node, and the necrosis and inflammation within the tumor are well known. In our cases, both 81-year-old man and 58-year-old man were visited our clinic, presented with upper lateral neck mass that had been present for the last few months. We operated the excisional biopsy in level ll of neck. The pathologic examination was proven to be EPWT. We report the unique two cases of extraparotid Warthin’s tumor with literature review.
