Marfanoid habitus + Mucosal neuromas + Neck mass = MEN 2B (PMM) Pheo, Medullary thyroid CA (Calcitonin secreting), mucosal neuromas
thotcandyI knew it was MEN2B but forgot medullary ca of Thyroid is parafollicular/c cells which means Calcitonin, not T3/T4
Other answers:
AntiThyroglobulin: Hashimoto's (or other thyroiditis)
Dexamethasone suppression test: positive/suppressed in pituitary adenoma (acth secreting), negative/unresponsive in Adrenal hyperplasia/adenoma (suppressed by high dose) or ectopic acth (unresponsive to high dose)
Serum TSH test: for papillary or follicular ca, thyroid adenomas are usually cold but could also cause HyperT
TSHR antibodies: graves disease, hyperT+12020-02-06T05:23:50Z
to snoo-finity ... and beyond!
