Secretory Carcinoma of the Salivary Gland: A Rarity in Children

J Pediatr Hematol Oncol. 2022 May 1;44(4):167-172. doi: 10.1097/MPH.0000000000002304. Epub 2021 Sep 6.

Abstract

Originally described as mammary analog secretory carcinoma (SC), SC of the salivary gland is a rare malignancy with morphologic and molecular similarities to SC of the breast. We present 2 children with salivary gland SC with the classic ETV6-NTRK3 gene fusion, including 1 with lymph node metastases. Both patients underwent surgical resection and were in remission 24 months postsurgery. One patient was additionally found to have synchronous papillary thyroid carcinoma with a TFG-MET fusion. A review of published cases highlights the expanding molecular profile and confirms the favorable course of salivary gland SC after surgical resection.
