Presentation
Ectopic ACTH syndrome from small cell carcinoma often presents with hypokalemia, metabolic alkalosis and muscle wasting. This patient presented with Cushingnoid features which is unusual in such cases. [ncbi.nlm.nih.gov]

Cushingoid
She received chemotherapy and radiotherapy then and gradually lost her cushingoid appearance. This is the first reported case of clear cell sarcoma of the kidney with ectopic ACTH syndrome. [ncbi.nlm.nih.gov]

Leg Edema
We describe a 63-year-old man with metastatic LCNEC to the left temporomandibular joint (TMJ) who presented with progressive muscle weakness and bilateral lower leg edema for 2 weeks. [ncbi.nlm.nih.gov]

Respiratory Distress
A secondary E. coli infection was superimposed and the patient died of disseminated intravascular coagulation and adult respiratory distress syndrome. [ncbi.nlm.nih.gov]
Ten days after the start of ketoconazole, her cortisol level was 51.3 μg/dl (5–25.0); 24-h urine cortisol, 1202 μg/24-h total volume (20–90) and ACTH, 235 pg/ml ( Bilateral pneumonia due to MRSA and respiratory distress occurred due to her immunosuppressive [edmcasereports.com]

Rectal Mass
A 25-year-old black homosexual was noted to be hypertensive, hypokalemic, and to have a rectal mass. Histopathology of the biopsied lesion revealed a mixture of poorly differentiated squamous cell and undifferentiated small cell carcinoma. [ncbi.nlm.nih.gov]
-
Dysphagia
He had dysphagia, weight loss and hoarseness of voice. Lab tests potassium of 2.5 mmol/l, with normal sodium, urea, creatinine. Bicarbonate 35 mmol/l. [endocrine-abstracts.org]

Suggestibility
These data suggested a possibility that SCLC secreted ACTH and caused EAS in this patient. [ncbi.nlm.nih.gov]

Limb Weakness
A 48 years old man, HIV infected, was admitted with polyuria, polidipsia and lower limb weakness. He had hipertension, crackles in the right hemithorax and linphanedophathy. [imed.pub]
Workup
The diagnostic workup is difficult, can last more than 6 months ( 50% of cases), and the underlying tumour is still frequently not located (12%). [ncbi.nlm.nih.gov]

X-Ray

Mediastinal Mass
For all six patients, the high dose (8 mg) dexamethasone suppression test (HDDST) showed lack of suppression, computed tomography (CT) scanning documented anterior mediastinal masses, and the mediastenal tumors removed were confirmed as ACTH secreting [ncbi.nlm.nih.gov]
In addition to facilitating tumor location, CT with contrast for mediastinal masses could help surgeons to assess the invasion of tumors and estimate the feasibility of complete resection prior to surgery ( Figure 1B ). [dovepress.com]

Anterior Mediastinal Mass
For all six patients, the high dose (8 mg) dexamethasone suppression test (HDDST) showed lack of suppression, computed tomography (CT) scanning documented anterior mediastinal masses, and the mediastenal tumors removed were confirmed as ACTH secreting [ncbi.nlm.nih.gov]
Ultrasound
-
Enlargement of the Liver
A computed tomographic (CT) scan revealed intact pituitary and enlarged adrenal glands. Liver metastases were seen but the primary neoplasm was not found. Treatment with aminoglutethimide and other therapeutic measures were unsuccessful. [ncbi.nlm.nih.gov]
Biopsy
-
Liver Biopsy
Liver biopsy confirmed metastatic anorectal carcinoma, and immunohistochemical stains of the rectal biopsy were positive for ACTH and neuron-specific enolase. [ncbi.nlm.nih.gov]
Liver biopsies were also positive for the neuroendocrine markers CgA, synaptophysin, neuron-specific enolase, and CD56. Cancer antigen 19-9 levels were very high at 2027.9 U/mL (reference range, 35 U/mL). [consultant360.com]
CT-guided liver biopsy revealed tumour cells of neuroendocrine origin consistent with carcinoid tumour, and urinary 5-hydroxyindole-acetic acid (5HIAA) was high (see table). [pmj.bmj.com]
Treatment
MTP treatment was started to reduce cortisol production. ACTH levels and cortisol and UFC levels were normalised and the ACTH-producing lung tumour was ablated after MTP treatment. [ncbi.nlm.nih.gov]
Prognosis
MAIN OUTCOME MEASURES: Etiologies, clinical, biochemical and radiological features, prognosis, and treatment were described. [ncbi.nlm.nih.gov]
Etiology
However, the 6-mm tumor size cut-off value provided 96% specificity and may be a reasonable threshold to proceed with surgery without the need for IPSS when the biochemical data support a pituitary etiology. [ncbi.nlm.nih.gov]
Treatment and prognosis Management depends on the specific etiology 6. [radiopaedia.org]
Furthermore, if the lung nodule is a benign lung hemangioma, we recommend that physicians not exclude it as the etiology of Cushing syndrome. [kjim.org]
Epidemiology
Although diagnostic evaluation is similar to that in adults, the variation in epidemiology may sway investigations, leading to inappropriate and/or incomplete diagnostic interventions. [ncbi.nlm.nih.gov]

Pathophysiology
Despite the progress achieved in elucidating the pathophysiology of Cushing's syndrome, clinicians continue to experience diagnostic and therapeutic challenges. [ncbi.nlm.nih.gov]

Prevention
The patient presented cachexia and developed multiple pulmonary abscesses that also prevented surgical treatment, thus he was treated with percutaneous ethanol injection guided by CT of the left adrenal tumor. [ncbi.nlm.nih.gov]
Prevention: Prompt treatment of tumors may reduce the risk in some cases. Many cases are not preventable. [uclahealth.org]
