Genomic abnormalities in some types of primary salivary gland tumors can also be detected in salivary gland-like primary tumors of the breast (e.g., polymorphous adenocarcinoma with HMGA2 or PLAG1 rearrangement; Secretory carcinoma with T (12; 15) fusion with ETV6-NTRK3; or adenoid cystic carcinoma with t(6; 9), resulting in MYB-NFIB fusion) (14).AcCC commonly occurs in salivary glands and resembles salivary gland acinic cell carcinoma morphologically when found in the breast. This evidence concerns the gene ETV6 and acinar cell carcinoma.
