Acinic cell adenocarcinoma (ACC) is a low-grade malignant salivary neoplasm that constitutes approximately 17% of all primary salivary gland malignancies. In the head and neck region, the parotid gland is the predominant site of origin and ACC is usually more frequent in women than men. Previous radiation exposure and familial predisposition are some of the risk factors for ACC. ACCs rarely involve minor salivary glands constituting only 13-17% of all minor salivary gland tumours. Generally, a slowly enlarging mass lesion in the tail of the parotid gland is the most frequent presentation. ACC has a significant tendency to recur, metastasise and may have an aggressive evolution. Therefore, a long-term follow-up is mandatory after treatment. Here we report the case of a woman in her 60s with an ACC in association with the labial minor salivary gland, presenting in the post-treatment period of squamous cell carcinoma of the tongue.
腺泡细胞腺癌（ACC）是一种低度恶性的涎腺肿瘤，约占所有原发性涎腺恶性肿瘤的17%。在头颈部区域，腮腺是主要的起源部位，ACC在女性中通常比男性更常见。既往放疗暴露和家族易感性是ACC的一些危险因素。ACC很少累及小涎腺，仅占所有小涎腺肿瘤的13-17%。一般来说，腮腺尾部缓慢增大的肿块病变是最常见的表现。ACC有显著的复发、转移倾向，可能会有侵袭性进展。因此，治疗后必须进行长期随访。在此，我们报告一例60多岁女性，其唇部小涎腺发生ACC，该病例出现在舌鳞状细胞癌的治疗后期。
