In some cases, Cushing syndrome results from a pituitary adenoma making excess ACTH, and in those situations it's called Cushing disease.

在某些病例中，库欣综合征是由垂体腺瘤制造过多促肾上腺皮质激素导致的；在这种情况下，它被称作库欣病。

Low ACTH levels can be seen in adrenal adenomas and carcinomas, whereas high ACTH levels can be seen in Cushing disease and ectopic ACTH production.

肾上腺腺瘤和肾上腺癌会检测出低水平ACTH，库欣病和异位ACTH综合征会检测出高水平ACTH。

The leading cause of that is a pituitary adenoma, which is a benign tumor of the pituitary gland- and this specific condition is called Cushing disease.

垂体腺瘤是导致这一失常的主要原因，这是一种位于垂体的良性肿瘤，在这种特定情况下被称为库欣病。

It can be exogenous, meaning drug-related, or endogenous, meaning that it's from an adrenal tumor or excess ACTH from a pituitary adenomas, in which case it's called Cushing disease or from an ectopic site like small cell lung cancer.

它可以是外源性，也就是药物相关；或内源性，也就是由肾上腺肿瘤或由垂体腺瘤分泌过多ACTH造成，这种情况下叫做库欣病，或是源于异位分泌，比如小细胞肺癌。
