How is MTC presentation?

Neck mass, pressure symptoms (dysphagia/dysphonia) or w/distant metastasis. Extensive MTC may present w/frequent loose stool and vasomotor flushing resulting from coincident secretion of peptides. In all cases a family hx should be taken to include first and second degree relatives to search for features of MTC and other endocrinopathies that may occur w/MTC.
