Aims and Objectives
Thyroglossal duct cyst (TDC) is a common congenital cyst with an incidence of about 7%. Thyroglossal duct cyst carcinoma (TDCC) is a rare sequel which arises from TDC and has an incidence of about 1%. As these are rare, they do not have well-defined management guidelines. The aim of this study was to analyse the clinical profile and pathological characteristics of patients with thyroglossal duct cyst carcinoma and to propose a protocol for their treatment and follow-up.
Materials and Methods
A retrospective study was done from January 2000 to December 2019. All the clinical details, imaging characteristics, treatment and histopathology were analysed.
Results
The mean age group in our study was 37.9 years with a female preponderance. The clinical features like rapid increase in size, fixity of the lump and lymph node metastasis were not very common. Seventy-five percent of our patients who underwent imaging had suspicious characteristics. Fifty-six percent of our patients had FNAC suggestive of TDCC. Fifty percent of our patients had concomitant thyroid carcinoma. None of our patients had distant metastasis at follow-up.
Conclusions
TDCC is rare and a disease of young adulthood and usually has good prognosis. It may be a clinical surprise or a small lesion which can be detected with ultrasound and targeted FNAC. There is high rate of concomitant thyroid carcinoma and hence needs careful assessment. Sistrunk’s procedure with total thyroidectomy either staged or simultaneously has good outcome and permits adjuvant treatment.
