Rare bizarre giant cells are seen
 
Binucleation is common
 
Cytoplasm is granular; small red-purple granules are seen in DQ and rare cases may show melanin pigment
 
 
 
IHC will help:  
 
Positive = CT, CEA, NE markers, TTF1, PAX8, congo red
 
Negative = TG
 
 
 
MTC occurs in sporadic and heritable forms.
 
Sporadic MTC (70-80% of cases) typically presents as a SOLITARY thyroid nodule in adults.
 
 
 
Patients with hereditary MTC usually develop multifocal bilateral thyroid tumors, and the age of presentation varies with the syndrome. Hereditary syndromes include Multiple Endocrine Neoplasia (MEN) type 2A, familial medullary thyroid carcinoma, and MEN type 2B.
 
 
 
MEN2 and FMTC show an AUTOSOMAL DOMINANT mode of inheritance and are associated with pathogenic germline mutations of the RET gene, encoded on chromosome 10, that result in constitutive activation of the RET receptor tyrosine kinase.
