Unusual loco-regional presentation in papillary carcinoma of thyroid: A case series

ABSTRACT

BACKGROUND: Papillary carcinoma of thyroid (PTC) is usually indolent with good prognosis and excellent long-term survival. However, PTC sometimes presents itself in unusual situations, posing diagnostic and therapeutic challenges. Owing to paucity of data, there is lack of consensus as to what treatment should be prescribed in patients with loco-regional spread other than the usual sites. MATERIALS AND METHODS: Six patients of PTC presenting with involvement of the aero-digestive tract, retropharyngeal, and para-pharyngeal lymph nodes and great vessels of the neck are included in this case series. RESULTS AND CONCLUSION: Though rare, unusual loco-regional presentation of PTC poses challenges in diagnosis and treatment. A keen clinical sense is paramount in effectively diagnosing these cases. Aggressive surgical resection and reconstruction results in good functional and aesthetic outcomes. Further studies are required for establishing specific guidelines on the approach to the treatment of these cases
