A Rare Papillary Thyroid Carcinoma Variant; How Aggressive We Should Be? Case Report

Cribriform Morular Variant (CMV) of Papillary Thyroid Carcinoma (PTC) is a rare type of thyroid papillary neoplasm. It is more prevalent in patients with Familial Adenomatous Polyposis syndrome (FAP), however sporadic CMV-PTC has been described. Due to a low prevalence of this condition, recent consensus guidelines do not state a specific therapeutic approach for this variant. We present a 20-year-old woman with PTC-CMV treated with a total thyroidectomy alone, with no evidence of recurrence at the one year follow up. More aggressive treatments that include lymph node dissection and adjuvant radio ablation have been described. This case shows that patients with this variant can be treated with a more conservative approach similar to that of variants that are at low risk for recurrence.
