Papillary Carcinoma Within a Thyroglossal Duct Cyst

Area of Science:

• Head and Neck Surgery
• Endocrinology
• Surgical Oncology

Background:

• Thyroglossal duct cysts (TGDCs) are congenital anomalies typically found in the neck's midline.
• Malignant transformation within TGDCs is exceptionally uncommon, with papillary carcinoma being the predominant subtype.
• Diagnosis of carcinoma within a TGDC is often incidental and confirmed after surgical resection.

Observation:

• A 38-year-old female presented with a thyroglossal duct cyst.
• Diagnostic workup revealed papillary carcinoma arising within the TGDC.
• The patient underwent surgical intervention for the condition.

Findings:

• The patient was treated with a Sistrunk procedure, a standard surgical approach for TGDCs.
• Following the Sistrunk procedure, a total thyroidectomy was performed.
• This combined approach addresses both the cyst and potential thyroid involvement.

Implications:

• This case highlights the importance of considering malignancy in TGDCs, even when rare.
• Surgical management involving Sistrunk procedure and thyroidectomy can be effective for TGDC papillary carcinoma.
• Further research may elucidate optimal diagnostic and management strategies for these rare presentations.
