Cribriform-morular variant of papillary thyroid carcinoma (CMVPTC) is a rare variant of papillary thyroid cancer mostly occurring in young females under the age of 30. CMVPTC is associated with familial adenomatous polyposis coli and has an excellent prognosis with most patients surviving upwards of 20 years. We describe the clinical course of an aggressive variant of CMVPTC in a 42-year-old male with the first known reported features of neuroendocrine differentiation (the unusual histological features are published elsewhere in a separate article (Cameselle Teijeiro, J., et al. Am. J. Clin. Pathol., 131:134-142, 2009). The patient survived just 23 months from diagnosis and we outline our management here including the use of radiolabelled Yttrium 90 therapy.
