title: A rare case of iliac crest metastasis from acinic cell carcinoma of parotid gland.
abstract: A case of acinic cell carcinoma of the right parotid gland metastasizing to the right iliac crest is presented. Generally, for this rare low-grade malignant salivary gland neoplasm, 20% of cases may have local recurrences whereas about 10% of cases have distant metastases. They may arise many years after the initial presentation of the original tumor. The most frequent locations are the cervical lymph nodes, liver, lungs, contralateral orbit and bones. Occurrence in the appendicular skeleton is very rare and in our knowledge this is the first report of metastases to the pelvis.
