小涎腺肿瘤较少见,占头颈部肿瘤2％以下,其中61％为良性,39％为恶性。良性肿瘤中多形性腺瘤占90％以上,其余主要是单形性腺瘤。作者研究了10,119例潘检资料,不包括腮腺和颌下腺,26例来源小涎腺良性肿物,其中17例为多形性腺瘤,9例为单形性腺瘤。单形性腺瘤发病年龄在42～69岁,性别无明显差别,位于上唇者8例,下唇者1例。单发性肿瘤临床表现是相对的质硬,多数粘膜下肿块能自由活动,韧而轻压缩感,表面粘 Small salivary gland tumors are rare and account for less than 2% of head and neck tumors, of which 61% are benign and 39% are malignant. Polymorphic adenomas account for more than 90% of benign tumors, and the rest are mainly monomorphic adenomas. The authors studied 10,119 cases of pan examinations, excluding parotid glands and submandibular glands, and 26 cases of benign masses of small parotid glands, of which 17 cases were pleomorphic adenomas and 9 cases were monomorphic adenomas. The onset age of monomorphic adenomas was between 42 and 69 years old, with no significant difference in gender. Eight cases were located in the upper lip and one in the lower lip. The clinical manifestations of single tumors are relatively stiff, most of the submucosal masses are free to move, tough and lightly compressed, and the surface is sticky.
