Cervical tumor by ectopic salivary gland.

Heterotopic salivary tissue is a rare lesion, although most authors agree that anomalous embryologic development of salivary tissue is the main cause. One case of cervical tumor by ectopic salivary gland is reported, and existent literature is reviewed. A 26-year-old woman was operated on for a cystic tumor in the midline of the neck diagnosed as thyroglossal cyst in the hyoid region. After Sistrunk operation, the recurrence was immediate. A second operation was performed, and a solid tumor located between muscles of the tongue was resected. A long tract opening in recurrent cervical cystic tumor was also removed. No recurrence was evident at 1 year after surgery. Pathological examination of the excised mass revealed an ectopic salivary gland with serous and mucinous acini located between muscles of the tongue. This is a rare case report of a cervical fistula by ectopic salivary gland surrounded by muscles of the tongue draining into a cystic tumor in the hyoid midline lesion. Recurrence of thyroglossal cyst after a correct surgical resection must be suspected as an ectopic salivary tissue. Also when a cystic neck tumor is present, an ectopic salivary gland must be suspected.

Ectopic thyroid tissue in the head and neck.

A review has been performed of thyroid ectopia seen during a 10 year period. There were five cases of total ectopia; three of these were lingual thyroids, one situated in the perihyoid region had been clinically diagnosed as a thyroglossal cyst, while the fifth presented as a tumor in the lateral neck. In the same period 41 thyroglossal cysts were removed. None of these showed uptake on technetium scintigraphy. Thyroid tissue was present in the cyst walls in 41% of cases. Scintigraphy should be performed routinely if the clinical picture is at all compatible with thyroid ectopia.
