“…Aetiopathogenesis is unknown but it is believed to be related to embrionary development ( 1 , 2 , 4 , 5 , 13 ). In 1968, Willis suggested 3 general hypotheses: a) abnormal persistence and development of vestigial structures; b) the abnormal differentiation of local tissues; and c) the dislocation of a portion of a definitive rudimentary organ during its movement and development ( 2 , 8 ). Although, Hsu et al ( 16 ) reported a case of a family with five generation suffering salivary gland heterotopias in the neck suggesting the existence of an autosomal dominant inheritance, some authors explain the choristoma’s origin as a type of metaplasya or development disorder where undifferentiated stem cells become mature salivary tissue ( 12 ).…”

“…The most described malignant neoplasm is mucoepidermoid carcinoma ( 8 ). In the diagnosis of a ma-lignant neoplasm of salival aberrant tissue, it is important to consider the possibility of it being a metastasis of a primary salivary gland tumour ( 2 , 6 , 8 ).…”

“…Choristoma removal is only necessary when there are signs of infection or neoplasm ( 1 , 13 , 17 ). In the other hand, some authors prefer the complete removal of the mass ( 1 , 2 , 6 , 12 , 18 ). Although malignization is very rare, choristomas are imma-ture in nature, which theoretically increase the chancy to malignization ( 19 ).…”

Salivary gland choristoma (SGCh) is defined as the presence of normal salivary tissue in an abnormal location. It is a rare entity in oral and maxillofacial region and its ethiology is unknown. The typical presentation of salivary gland heterotopia is an asymptomatic mass that may or may not produce saliva. Some examples of ectopic salivary tissue in the pituitary gland, in the lymph nodes, in the middle ear, in the neck, in the jaw, in the thyroid gland, in the mediastinum and in the rectum have been documented in literature. We report the case of a 61-year-old male presented with a bilateral tumorlike mass in the cheek. The mass was painless, of fibrous consistency and had size change with time. The histological diagnosis was salivary gland choristoma in the buccinator muscle. In this article, we will revise the characteristic of salivary gland heterotopias and we present a report case that has not been described in literature: a bilateral choristoma of salivary gland in the buccinator muscle, which should be included in the differential diagnosis of head and neck masses. Key words:Choristoma, heterotopias, ectopic tissue, salivary gland, buccinator muscle.
