涎腺的腺泡细胞腺癌病理特征虽然早在50年代就已得到充分确认(最初曾以涎腺的一种特殊类型肿瘤来分类),但目前对该肿瘤的病理诊断和预后判定仍常有困难。其原因在于大多数外科病理检验室所检测到的涎腺肿瘤仅占全部送检标本的很小部分,而腺泡细胞腺癌又仅占涎腺肿瘤的2.5％左右。此外,在组织病理学检查中尚可见许多其它肿瘤的细胞和组织,具有很大的多形性。鉴于
The parotid gland acinar cell adenocarcinoma pathological features have been well established as early as the 1950s (originally classified as a specific type of tumor in the parotid gland), but the pathological diagnosis and prognosis of the tumor are still common. difficult. The reason is that the salivary gland tumors detected in most surgical pathology labs account for only a very small part of the total enrolled specimens, while acinar cell adenocarcinomas account for only about 2.5% of salivary gland tumours. In addition, many other tumor cells and tissues are still visible in histopathological examinations and have a great deal of polymorphism. Given
