Salivary gland tumors are uncommonly seen and account for less than 3% of the head and neck tumors. Pleomorphic adenoma is a well-described benign tumor of the salivary glands, originating from myoepithelial and intercalated duct cells. It is most commonly found in major salivary glands. We present a rare and unusual case of pleomorphic adenoma of the minor salivary glands in the lower lip. The tumor was diagnosed upon excision of 1.5 × 1.2 cm(2) well-circumscribed nodule at the junction of the lower lip and chin in a 46-year-old man. The histopathological analysis confirmed presence of an epithelial salivary gland tumor with islands of plasmacytoid cells, and duct-like structures within a variable and mixed stroma.
涎腺肿瘤较为少见，占头颈部肿瘤的比例不到3%。多形性腺瘤是一种已被充分描述的涎腺良性肿瘤，起源于肌上皮细胞和闰管细胞。它最常发生于大涎腺。我们报告一例下唇小涎腺多形性腺瘤的罕见病例。该肿瘤是在一名46岁男性下唇与颏部交界处切除一个1.5×1.2 cm²边界清楚的结节后被诊断出来的。组织病理学分析证实为上皮性涎腺肿瘤，伴有浆细胞样细胞岛以及在不同的混合性间质内的导管样结构。
