Severe Ectopic Adrenocorticotropic Hormone Syndrome Due to Pulmonary Carcinoid Tumor: A Case Report and Literature Review.
AACE Clin Case Rep
August 2024
Division of Endocrinology, Department of Medicine, Duke University, Durham, North Carolina.
Background/objective: Pulmonary carcinoid tumors are a rare cause of Cushing's syndrome and usually present with an indolent course. Here, we present a case of rapid onset and severe Cushing's syndrome due to a typical pulmonary carcinoid tumor.
Case Report: A 32-year-old woman developed diabetes, hypertension, and weight gain of 50 pounds over 3 months.

Background: Adrenocorticotropin (ACTH)-dependent Cushing's syndrome can arise from a pituitary tumour (Cushing's disease) or an ectopic ACTH-secreting tumour, making precise differentiation essential for effective treatment. Bilateral inferior petrosal sinus sampling (BIPSS) is the gold standard for this differentiation, but false-negative results can limit its accuracy. Adding prolactin (PRL) measurement to BIPSS has been proposed to improve diagnostic precision.

Department of Endocrinology, Beijing Hospital, National Center of Gerontology, Institute of Geriatric Medicine, Chinese Academy of Medical Sciences, No. 1 Dahua Road, Dongcheng District, Beijing 100730, China.
Ectopic corticotropin-releasing hormone (CRH) syndrome, a rare subtype of adrenocorticotropic hormone-dependent Cushing syndrome, is associated with tumors of diverse origins. Here, we present a case of a 37-year-old female diagnosed with ectopic CRH syndrome secondary to rectal large cell neuroendocrine carcinoma, a hitherto unprecedented site for CRH-secreting tumors. The patient presented with classical features of Cushing syndrome, supported by laboratory evidence of hypercortisolemia and disrupted diurnal cortisol secretion.

Ectopic adrenocorticotropic hormone (ACTH)-dependent Cushing is a rare syndrome. We present a case that illustrates the diagnostic and therapeutic challenges of ectopic Cushing. A 35-year-old woman presented to the outpatient clinic for evaluation of progressive weight gain, muscle weakness, easy bruising, uncontrolled hypertension, and hyperglycemia.

Endocrinology, PGIMER, Chandigarh, India.
An adult man in his 30s with newly diagnosed diabetes mellitus and hypertension presented with a 33 lb weight gain, generalised swelling and classic Cushingoid features, including proximal muscle weakness, easy bruisability, wide violaceous striae and a painless, progressively enlarging right-sided neck swelling over the past month. Physical examination revealed a 4×4 cm thyroid mass, facial plethora and dorsocervical fat pads. Laboratory investigations confirmed hypercortisolism with elevated cortisol and Adrenocorticotropic Hormone(ACTH), with non-suppression on dexamethasone suppression tests.
