摘　　要：患者,男,58岁,因“发现左侧颌下区包块1个月余”于2014年9月7日入院。入院前1个月患者体检时发现左侧颌下区一约核桃大小包块,未出现发热、吞咽疼痛及梗阻感、舌体麻木、舌体活动受限、流涎等不适症状。专科查体：左侧颌下区扪及一约4.0cm×3.5cm大小包块,质硬活动,无触压痛,表面皮肤无红肿破溃。涎腺超声提示左侧颌下腺实质性占位伴钙化,增强CT示左侧颌下腺内占位性病变（图1a、b）。A case of Sehwannoma in the submandibular gland was reported which had been misdiagnosed as pleomorphic adenoma before operation. The tumor was originated from lingual nerve which in turn invaded the Schwann membrane near the submandibular ganglion.
