Salivary heterotopia of the parathyroid gland: A report of two cases and review of the literature

Salivary gland choristoma in the buccinator muscle: A case report and literature review

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.

Basal cell adenocarcinoma arising in salivary gland metaplasia of the breast: a novel salivary gland-type tumor developing in the breast

A variety of salivary gland-type lesions occur in the breast. Three cases of a novel mammary carcinoma arising in a background of salivary gland metaplasia and morphologically similar to basal cell adenocarcinoma of the salivary gland are presented. The clinical presentation, morphologic features, treatment, and follow-up of these cases are discussed.

Heterotopic salivary gland presenting as a supra-clavicular swelling

A 5-month-old female was referred to the paediatric surgery clinic with a neck swelling in the right supra-clavicular region. This was thought clinically to be cystic hygroma. Pathology showed an ectopic salivary gland. This should be added to the list of differential diagnoses of neck swelling in childhood.
