Salivary gland choristoma on tonsil – A case report and review

Abstract

The salivary choristoma or heterotopic salivary gland is defined as a tumor-like growth of otherwise normal salivary gland found in an abnormal location. Although histologically there is evidence of hetertopic salivary gland tissue in palatine tonsil rarely it manifests as visible mass with only isolated case reports having been found. In this article, we present a case with salivary gland choristoma on palatine tonsillar wall and a brief review.

“…In the fourth case, Golan reported bilateral ectopic salivary gland tissue in the case of routine tonsillectomy. 17 The last case with salivary gland tissue on palatine tonsillar wall, was presented by Shyamala et al, 18 in 2017.
