Abstract Surgical pathology of the neck constitutes an important field in pediatric surgery. Nevertheless, a significant number of adult patients may present neck pathology, and cervical midline cystic congenital lesions, specifically those related with abnormal embryologic development of the thyroid gland, represent the most frequent type of abnormality.

We report a case of papillary carcinoma originating in a thyroglossal duct cyst in an adult woman; very few cases have been reported in the lityerature. We discuss diagnosis and management, and include a literature review. A lo largo de este trayecto pueden persistir remanentes del tejido tiroideo que, finalmente, dan origen al quiste tirogloso.

Epidermoid cysts are slow growing and usually asymptomatic, but they may become inflamed or The head and neck sites affected most frequently secondarily infected, resulting in pain and tenderness.

Orbital dermoid malignancies, including basal cell carcinoma, Bowen cysts have been classified as either exophytic or disease, Squamous cell carcinoma, and mycosis endophytic, according to their site of attachment in fungoides have been reported in epidermoid cysts relation to the orbital rims. The exophytic cysts grow Debaize et al. The cyst can occur at any age, externally and are discovered in childhood, whereas most common in the third and fourth decades of life.

They could represent a variant form of the thyroglossal Suggested etiology includes sequestration of duct cyst.
