differentiate cushings syndrome from cushings disease >???

[ArchivalUser]

Cushing disease=Hypercortisolism due to hypersecretion of ACTH by pitutary.Can be benign pitutary adenoma.
Cushing syndrome=excesive corticosteroid due to drugs or due to excessive corticosteroid from adrenal cortex.(30%)
but 40% of cases are due to cushing ds.

so what do u label it when ACTH is from some other ectopic source as from small ca of lung??
ds or syndrome?

its paraneoplastic syndrome -ACTH
small cell -eatonlambert syndrome

it is paraneoplastic but still the cause of "cushing syndrome",these pts have hyperpigmentation and hypkalemia.

Eaton Lambert=weakness esp of proximal muscle of limbs.Typically improve with activity,unlike myesthenia.
diag:electrophysiologically(muscle response to stimulation increases)
treat:plasmapheresis and immunosuppresion
