Acute Lymphoblastic Leukemia with Isolated Adrenocorticotropic Hormone Deficiency

Abstract

A 57-year-old female was admitted to our hospital because of Philadelphia chromosome (Phipositive acute lymphoblastic leukemia (ALL). On admission, disturbance of consciousness and hyponatremia were recognized. The patient's endocrinological data showed low levels of adrenocorticotropic hormone (ACTH) (less than 5 pg/ml) and cortisol (5.9 μg/dl). Other anterior pituitary hormones were normal. Plasma ACTH and cortisol did not respond to the corticotropin releasing factor (CRF) test. A diagnosis of isolated ACTH deficiency was made. This is a rare case of isolated ACTH deficiency complicated with hematological malignancies.
