Ectopic Salivary Gland - A Possible Differential Diagnosis of a Branchial Cleft Cyst.

Background: Branchial cleft cysts or fistulae are common in pediatric surgical pathology and are cured by surgery. Lesions in this area may not show the classical features of a cyst or duct lined by squamous or respiratory epithelium and other differential diagnoses should be considered. Case report: A seven-year-old otherwise healthy boy presented with bilateral swelling of the lower neck and reported intermittent secretion of clear fluid on the right side. Excision of the right sided lesion revealed an ectopic salivary gland, the excision of the left showed only subtle fibrosis. Conclusion: Ectopic salivary glands may occur in the distribution of branchial cleft remnants. Clear fluid drainage (saliva) may be a clinical clue that these are not branchial cleft cremnants.
