ACTH
Also known as: adrenocorticotropic hormone
Use
Anti-adrenocorticotropic hormone (ACTH) immunohistochemistry serves as a useful diagnostic marker for identifying ACTH-producing corticotroph cells, particularly useful in classifying pituitary tumors and evaluating pituitary disease. Additionally, this stain may react with non–pituitary tumors, for example small cell carcinoma of the lung, which can produce ectopic ACTH leading to paraneoplastic syndromes.
