Heterotopia or choristoma are characterized by a histologically normal tissue proliferation or nodule of a tissue type not normally found in anatomic site. Exact aetiopathogenesis of heterotopic salivary gland (HSG) is debatable. The histopathological finding of heterotopias is rare. In this article, we present a patient who underwent tonsillectomy for chronic recurrent tonsillitis with asymptomatic tonsillar mass and had chronic inflamed tonsillar tissue with HSG tissue in the palatine tonsil according to histological examination. Also we present a brief review about pathogenesis, pathologic features, tumorigenic potential, treatment and prognosis of HSGs. It could be one of the causes of recurrent tonsillitis. Also clinicans should be differentiate it from the tonsillar neoplasia due to similar appearance and should be aware of the fact that the neoplastic transformation of a HSG is a probablity.
