RESUMO
The author reports a case of congenital fistula from an accessory parotid gland and describes its diagnosis and treatment. The patient was referred to the author's clinic for evaluation of a continuous serous discharge from a small orifice in the left cheek near the angle of the mouth. A left preauricular appendix was also noted. Fistulography detected an aberrant duct leading to an accessory parotid gland. The main parotid gland and its duct were normal. The anomalous duct was dissected in continuity with a small ellipse of skin and sutured to the buccal mucosa. The patient's recovery was uneventful. The author also discusses the embryologic origin of this rare anomaly.

As fístulas salivares de origem congênita são má formações de incidência rara. Devem ser diferenciadas de fístulas de 2° arco branquial, pelas características clínicas distintas, como a ausência de episódios de infecção e drenagem abrupta, que aumenta durante a alimentação. Dúvidas ainda existem com relação à sua etiologia. As hipóteses existentes cogitam a migração anormal de tecidos embrionários e a heteroplasia de células ectodérmicas, que regridiriam no processo de diferenciação celular. A fistulografia da lesão mostra fundo de saco arboriforme e ajuda no diagnóstico diferencial da lesão. O tratamento é cirúrgico, com ressecção do trajeto da lesão e da glândula que a originou. Apresentamos três casos de fístulas salivares congênitas.
Salivary gland fistulas are rare malformations and should be differentiate from others draining sinuses pathologies, especially from the second branchial cleft sinuses. Precise pathogenesis is not fully understood. Clinically, the episodes of drainage are usually associated with a sense of fullness in the affected area and the amount of drainage usually increases during eating or mastication. A preoperative sinugram is helpful. The treatment is its excision. We present three cases of unusual salivary gland fistula.

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.
