Acinic cell carcinoma is an uncommon salivary gland neoplasm that is generally indolent. Most cases arise in the major salivary glands, mainly the parotid. Generally, they are low-grade neoplasms with a 20 % rate of local recurrences and about 10 % rate of metastases which may appear many years after the initial presentation of the original tumour. The most frequent locations of the metastasis are the cervical lymph nodes, liver, and lungs. Metastases at the level of the spine are extremely rare. In this article, we report a case of a patient with an acinic cell carcinoma of the right parotid gland, who presented a distant metastasis at the level of the sacrum 8 years after surgical treatment of the initial tumour.

Keywords : Acinic cell carcinoma; salivary gland cancer; parotid gland; metastasis.
