C? Since it comes from C-cells its prevalence shoudn'y be influenced by the funtional status of follicular cells. What do you think? Follicular adenoma I think should be more common in the hypethyroid group...

A Subacute granulomatous thyroiditis << doesnt Cause Permanent Hyppthyroidism

B Multinodular goiter ??

C Medullary carcinoma <<< Least Common in Neoplasms

D Hashimoto thyroiditis << MCly pts do not have a period of trasnient Hyperthyroidism

E Follicular adenoma <<<< Very Few pts show Signs of Hyperthyroidism but Mostly r Euthyroid.

SO i will go for B just bcos i dont know abt B wink

yes the answer is C. and the explanation which is just a single line, says what virgola said...C cells do not secrete thyroid hormones...well let me try to copy, paste the explanation for all of the choices.

(A) Incorrect. There may be a period of transient hyperthyroidism in this condition.
(B) Incorrect. A small number of persons with a multinodular goiter may develop a toxic multinodular goiter with evidence for hyperthyroidism.
(C) CORRECT. Medullary carcinomas, derived from interstitial 'C' cells, do not secrete thyroid hormone and are not associated with hyperthyroidism.
(D) Incorrect. There may be transient hyperthyroidism in association with Hashimoto thyroiditis early in the course of this disease, but eventually the patient becomes hypothyroid
(E) Incorrect. A small number of follicular adenomas may be 'toxic' adenomas and secrete thyroid hormone.

Man they r trying ask which following disease will have an equal chances of occuring in the Hyperthyroid pts n euthyroid pts.

SO regardless if the pt is hyperthyroid or euthyroid he/she have equal chances of having Medullary Ca.

Damn
