Cribriform-Morular Variant of Papillary Thyroid Carcinoma: a Clinical Surprise in a Routine Case

摘要

Cribriform morular variant of papillary thyroid carcinoma (CMV-PTC) is a rare variant. It is commonly associated with familial adenomatous polyposis. It is mostly seen in females below 30 years of age. We describe a male patient in his fourth decade of life, who presented with a solitary thyroid nodule and was evaluated and treated. The histopathology of the thyroid nodule was reported as CMV-PTC. In light of this finding, the patient was further investigated and treated for familial adenomatous polyposis (FAP), for which he was asymptomatic. Any patient diagnosed with CMV-PTC must also undergo colonoscopy to rule out FAP and receive appropriate treatment. Clinicians must be aware that this variant can be seen in men too.
