Adrenocorticotropic hormone-producing pheochromocytoma/paraganglioma are rare neuroendocrine tumours that co-secrete excess catecholamines and adrenocorticotropic hormone, resulting in Cushing syndrome. This review aims to summarize important patient characteristics, investigations, and outcomes in all cases reported in the English literature. A literature search was conducted to identify all English-language case reports and case-series describing adrenocorticotropic hormone-producing pheochromocytomas/paragangliomas. Relevant characteristics were systematically recorded. Cases that did not provide definitive evidence of an ACTH-producing pheochromocytoma/paraganglioma were excluded. Our search strategy identified 93 published cases that met the inclusion criteria. We additionally reported one patient for a total of 94 cases. Details related to patient characteristics, laboratory data, and outcomes were commonly underreported. The median age was 47 years and females accounted for 72% of cases. A cushingoid appearance was reported in 82% and hypertension in 86%. Infections were reported in 23% of patients. Urinary metanephrines were elevated at least 3-fold above normal in 74%. ACTH levels were high in 88% and inappropriately normal in 12%. The median 24-hour urinary cortisol was 21-fold the upper limit of normal. Adrenalectomy was performed in nearly all patients with 88% achieving cure of both catecholamine and glucocorticoid excess. A total of 11 patients died. Metastases were uncommon (6%). Adrenocorticotropic hormone-producing pheochromocytoma/paraganglioma is associated with considerable morbidity and mortality. It should be considered in the diagnostic workup of all patients with ectopic Cushing Syndrome. Surgical cure is achieved in most patients and infections are the leading cause of peri-operative mortality.

Background: Tumors of the paraganglionic system represent a distinct, albeit uncommon, clinical entity characterized by catecholamine hypersecretion and hemodynamic instability; initial pathologic examination often cannot predict benign vs malignant behavior. An analysis of the clinical outcome of patients with known malignant tumors may serve to enhance the initial evaluation and therapeutic plan of all patients presenting with pheochromocytoma or paraganglioma.
Methods: At the University of Texas M D Anderson Cancer Center, 30 patients with malignant abdominal paraganglioma and 20 patients with malignant pheochromocytoma were diagnosed between 1971 and 1995. Their medical records were reviewed with particular attention to clinical characteristics and disease outcome.
Results: Among the 30 patients with paraganglioma, 73% were men, and 90% were younger than 50 years at the time of diagnosis. Sixteen patients have remained alive with persistent disease 0.2 to 25 years after initial diagnosis while eight patients died of their disease within 0.8 to 32 years. Regional recurrence and skeletal metastases were the most prominent events. Among the 20 patients with pheochromocytoma, 60% were men and 70% were younger than 50 years at the time of diagnosis. Ten patients have remained alive with persistent disease 0.8 to 20 years after initial diagnosis while five patients died of their disease within 1.5 to 39 years. Hypertension was a prominent presenting feature and regional recurrence was the most frequent pattern of treatment failure.
Conclusions: Important clinical differences distinguish adrenal pheochromocytomas from extra-adrenal, abdominal paragangliomas. Patients with paragangliomas are, as a group, younger men, more likely to have malignant lesions and a more aggressive clinical course. Patients with malignant pheochromocytomas usually present with hypertension, are somewhat older, and have less aggressive disease.
