The diagnostic accuracy of fine-needle aspiration of salivary gland lesions is now widely accepted. The cytologic appearance of two rare monomorphic variants of pleomorphic adenomas is described. The trabecular-tubular adenoma consisted of a trabecular arrangement of uniform small cells with scant basophilic cytoplasm and round nuclei. No mucoid spheres were present. The canalicular adenoma also had a distinctive cytologic appearance consisting of papillae and interconnected canaliculi lined by a layer of columnar epithelium. Monomorphic adenomas have unique morphologic appearances that can be recognized in fine-needle aspiration cytology. Preoperative diagnosis can greatly aid the surgeon in the planning of definitive surgical excision of salivary gland neoplasms.
唾液腺病变细针穿刺的诊断准确性现已得到广泛认可。本文描述了多形性腺瘤两种罕见单形性变体的细胞学表现。小梁管状腺瘤由均匀的小细胞呈小梁状排列组成，细胞浆嗜碱性稀少，细胞核圆形。不存在黏液样球。管状腺瘤也有独特的细胞学表现，由乳头和相互连接的小管组成，内衬一层柱状上皮。单形性腺瘤具有独特的形态学表现，可在细针穿刺细胞学检查中识别。术前诊断可极大地帮助外科医生规划唾液腺肿瘤的确定性手术切除。
