Hypothesis: For papillary carcinoma in a thyroglossal duct remnant, complete wide excision of the remnant is adequate treatment.

BACKGROUND

Thyroglossal duct remnants (TGDRs) result from aberrant embryological development of the thyroid gland. During the fourth week of fetal development, the thyroid anlage arises from epithelium located in the floor of the pharyngeal gut and descends as a bilobed diverticulum. During its descent, the thyroid gland remains connected to the base of the tongue by the thyroglossal duct, which involutes as the thyroid reaches its final position in the neck by the eighth week of gestation. Persistence of this embryonic duct results in TGDRs.

These remnants, most typically cysts, occur in an equal sex distribution and may occur anywhere along the embryological route of descent of the thyroid gland in the following frequency: 2% intralingual, 24% suprahyoid, 60% between the hyoid and thyroid cartilage, and 13% substernal.¹ Approximately 31% of TGDRs occur . . .
