Significant differences in the global distribution of salivary gland tumors have been reported, but no formal study has been carried out here in Kano, the largest city in northern Nigeria. We therefore undertook this eight-year retrospective study of all histologically diagnosed salivary neoplasms at the histopathology laboratory of our referral teaching hospital in Kano. Seventy-eight salivary gland tumors were diagnosed during the eight-year study period accounting for 0.4% of all neoplasms. Benign tumors were more prevalent, comprising 56.4%, while malignancies were 43.6%. Pleomorphic adenoma and mucoepidermoid carcinoma were the commonest histological types constituting 48.7% and 23.1% respectively, while the most frequent sites were parotid, submandibular and minor salivary glands accounting for 49%, 26% and 24% respectively. As in most studies of black populations there were no adenolymphomas. Age distribution was bimodal with a benign peak in the third decade and a malignant peak in the sixth. Our findings were broadly similar to most other African reports but somewhat at variance with Western literature. Improved hospital attendance with more comprehensive reporting would yield more representative data.
已有报道称涎腺肿瘤的全球分布存在显著差异，但在尼日利亚北部最大的城市卡诺，尚未进行过正式研究。因此，我们对卡诺转诊教学医院组织病理学实验室所有经组织学诊断的涎腺肿瘤进行了这项为期八年的回顾性研究。在为期八年的研究期间，共诊断出78例涎腺肿瘤，占所有肿瘤的0.4%。良性肿瘤更为常见，占56.4%，而恶性肿瘤占43.6%。多形性腺瘤和黏液表皮样癌是最常见的组织学类型，分别占48.7%和23.1%，而最常见的部位是腮腺、颌下腺和小涎腺，分别占49%、26%和24%。与大多数黑人人群的研究一样，未发现腺淋巴瘤。年龄分布呈双峰型，良性肿瘤在第三个十年出现高峰，恶性肿瘤在第六个十年出现高峰。我们的研究结果与大多数其他非洲报告大致相似，但与西方文献略有不同。改善医院就诊率并进行更全面的报告将产生更具代表性的数据。
