Orifices at the lower neck: heterotopic salivary glands

Ectopic salivary gland fistula in the sternoclavicular joint region

Although rare, ectopic salivary gland fistula should be considered in the differential diagnosis when treating a fistulous lesion on the neck because its natural history and the level of difficulty of surgery are different from those of the branchial fistula.

Choristomatous polyps of the aural and pharyngeal regions: first simultaneous case

The first known case of embryological development of a salivary gland choristoma of the middle ear and a hairy teratoid (choristomatous) mass of the pharynx arising in the same patient is reported. On the day after the patient, a female, was born, a posterior pharyngeal mass was discovered, resected, and diagnosed histopathologically as a hairy teratoid (choristomatous) polyp. At 10 months of age, the patient underwent myringotomy and tympanostomy tube placement, and another mass was found in the left middle ear. This mass was diagnosed as a salivary gland choristoma. Our review of the literature showed that, consistent with our case, choristomas are more prevalent in females, and those in the middle ear almost always occur on the left side. Both types of polyps are rare and are thought to be due to errors in development of the second and first branchial arches.

Salivary gland choristoma of the anterior chest wall

Salivary gland choristoma (heterotopic salivary gland tissue) is a rare condition that occurs at various locations within the head and neck. Diagnostic criteria and embryogenesis of this entity remain unclear. Presented herein is the first reported case of salivary gland choristoma on the anterior chest wall. Surgical treatment is recommended.
