title: Solid blue dot tumour: minor salivary gland acinic cell carcinoma.
abstract: 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.
