Abstract
Pheochromocytoma or paraganglioma (PPGL) originating from chromaffin cells can produce diverse hormones in addition to catecholamines, including adrenocorticotropic hormone (ACTH). In pheochromocytoma, high levels of ACTH might not result in pigmentation as typically observed in Addison's disease, and patients might not exhibit the symptoms of Cushing's syndrome, despite ACTH-dependent hypercortisolism. A 63-year-old male patient with hypertension was admitted to our facility, and computed tomography (CT) revealed a large right adrenal tumor. Despite high plasma ACTH (700-1300 pg/mL) and serum cortisol (90-100 µg/dL) levels, no physical pigmentation or Cushingoid symptoms were observed. Urinary metanephrine and normetanephrine levels reached as high as 16.0 mg and 3.2 mg, respectively. 123I-metaiodobenzylguanidine (MIBG) scintigraphy was negative. Low-dose dexamethasone paradoxically increased ACTH and cortisol levels, indicating the potential positive feedback regulation of both hormones by glucocorticoids. The patient was diagnosed with an ACTH-producing pheochromocytoma and underwent successful laparoscopic surgery to remove the adrenal tumor under the intravenous administration of a high-dose α-blocker and hydrocortisone. The levels of ACTH, cortisol, and urinary metanephrine/normetanephrine returned close to normal after tumor removal. We report a rare case of pheochromocytoma with extremely high ACTH/cortisol production but without pigmentation or Cushingoid symptoms. We also reviewed previous reports of ACTH-producing PPGL regarding the paradoxical regulation of ACTH/cortisol by glucocorticoids, pigmentation, Cushingoid symptoms, and negativity of 123I-MIBG scintigraphy.

Preoperative management of patients with ectopic Cushing's syndrome caused by ACTH-secreting pheochromocytoma: a case series and review of the literature. J Endocrinol Invest 2023; 46:1983-1994.

Abstract
PURPOSE ACTH-secreting pheochromocytoma is a rare cause of ectopic Cushing's syndrome, posing a clinical challenge for the severity of its clinical presentation, the difficulty in the prevention and the management of surgical complications. Sparse data are currently available about the optimal preoperative management of the severe symptoms due to both hypercortisolism and catecholamine excess, especially regarding the role and timing of medical therapies. METHODS We present a series of three patients with ACTH-secreting pheochromocytoma. A brief review of the available literature evidence on the preoperative management of this rare clinical condition is also conducted. DISCUSSION Patients with ACTH-secreting pheochromocytoma show peculiarities as compared to other forms of ACTH-dependent Cushing's syndrome, in terms of clinical presentation, preoperative management, and peri- and post-surgical short-term outcome. Pheochromocytoma should be ruled out in patient with ectopic CS of unknown origin because of the high anesthesiologic risk of proceeding to surgery with an undiagnosed pheochromocytoma. Proper preoperative recognition of complications of both hypercortisolism and catecholamines excess is the key to prevent the morbidity and mortality of an ACTH-producing pheochromocytoma. In these patients the absolute priority is to control excessive cortisol secretion since the rapid correction of the hypercortisolism is the most effective treatment of all the related comorbidities and it is mandatory to prevent severe complications during surgery, opting if necessary for a "block-and-replace" regimen. CONCLUSION Our additional cases and this literature review could provide a better understanding of the complications to be evaluated at diagnosis and some suggestions on their management during the preoperative period.

Abstract
CONTEXT The characteristics of catecholamine-secreting pheochromocytomas have been well studied. However, less is known about the characteristics, management and outcome in patients with ectopic adrenocorticotropic hormone (ACTH) and/or corticotrophin-releasing hormone (CRH)-secreting pheochromocytomas. OBJECTIVE To review the characteristics and outcomes of ACTH- and/or CRH-secreting pheochromocytomas. DATA SOURCE A systematic search of PubMed/MEDLINE and Web of Science, identifying relevant reports published up to 10 February 2020. STUDY SELECTION Original articles, including case reports and case series, reporting individual patient data from patients with ACTH- and/or CRH-secreting pheochromocytomas. DATA EXTRACTION Information on sex, age, symptoms at presentation, comorbidities, biochemistry, imaging, histopathology, and outcomes was extracted. DATA SYNTHESIS We identified 91 articles reporting on 99 cases of ACTH- and/or CRH-secreting pheochromocytomas (CRH-secreting n = 4). Median age at diagnosis was 49 years (interquartile range 38-59.5) with a 2:1 female to male ratio. Most patients presented with clinical Cushing syndrome (n = 79; 81%), hypertension (n = 87; 93%), and/or diabetes (n = 50; 54%). Blood pressure, glucose control, and biochemical parameters improved in the vast majority of patients postoperatively. Infections were the most common complication. Most cases (n = 70, 88%) with reported long-term outcome survived to publication (median follow-up 6 months). CONCLUSION Ectopic ACTH- and/or CRH-secreting pheochromocytoma should be considered in patients presenting with ACTH-dependent Cushing syndrome and adrenal mass. Despite the challenge in diagnosis, patient outcomes appear favorable.

Abstract
Malignant pheochromocytomas (PCs) and paragangliomas (PGLs) are rare neuroendocrine neoplasms defined by the presence of distant metastases. There is currently a relatively paucity of data regarding the natural history of PCs/PGLs and the optimal approach to their treatment. We retrospectively analyzed the clinical, biochemical, imaging, genetic and histopathological characteristics of fourteen patients with metastatic PCs/PGLs diagnosed over 15 years, along with their response to treatment. Patients were followed-up for a median of six years (range: 1–14 years). Six patients had synchronous metastases and the remaining developed metastases after a median of four years (range 2–10 years). Genetic analysis of seven patients revealed that three harbored succinate dehydrogenase subunit B/D gene (SDHB/D) mutations. Hormonal hypersecretion occurred in 70% of patients; normetanephrine, either alone or with other concomitant hormones, was the most frequent secretory component. Patients were administered multiple first and subsequent treatments including surgery (n = 12), chemotherapy (n = 7), radionuclide therapy (n = 2) and radiopeptides (n = 5). Seven patients had stable disease, four had progressive disease and three died. Ectopic hormonal secretion is rare and commonly encountered in benign PCs. Ectopic secretion of interleukin-6 in one of our patients, prompted a literature review of ectopic hormonal secretion, particularly from metastatic PCs/PGLs. Only four cases of metastatic PC/PGLs with confirmed ectopic secretion of hormones or peptides have been described so far.

Abstract
In ectopic ACTH-secreting pheochromocytoma, combined ACTH-driven hypercortisolemia and hypercatecholaminemia are serious conditions, which can be fatal if not diagnosed and managed appropriately, especially when glucocorticoid-driven positive feedback is suggested with a high ACTH/cortisol ratio. A 46-year-old man presented with headache, rapid weight loss, hyperhidrosis, severe hypertension and hyperglycemia without typical Cushingoid appearance. Endocrinological examinations demonstrated elevated plasma and urine catecholamines, serum cortisol and plasma ACTH. Moreover, his ACTH/cortisol ratio and catecholamine levels were extremely high, suggesting catecholamine-dominant ACTH-secreting pheochromocytoma. Computed tomography revealed a large right adrenal tumor. 18F-FDG positron emission tomography showed uptake in the area of the adrenal tumor, while 123I-metaiodobenzylguanidine scintigraphy showed no accumulation. His plasma ACTH level paradoxically became elevated after a dexamethasone suppression test. After metyrapone administration, not only serum cortisol but also plasma ACTH levels were exponentially decreased almost in parallel, suggesting a glucocorticoid-driven positive-feedback regulation in this rapidly exacerbated ectopic ACTH-producing pheochromocytoma. Interestingly enough, plasma catecholamine levels were also decreased by metyrapone, although they remained extremely high. He became severely dehydrated due to hypoadrenalism requiring hydrocortisone supplementation. His clinical signs and symptoms were improved, and right adrenalectomy was performed uneventfully, resulting in complete remission of pheochromocytoma and Cushing's syndrome. A glucocorticoid-driven positive-feedback regulation in this ectopic ACTH-secreting pheochromocytoma created a vicious cycle with rapid exacerbation of both hypercortisolemia and hypercatecholaminemia with extremely elevated plasma ACTH level. Metyrapone was clinically effective to stop this vicious cycle; nonetheless, great care must be taken to avoid hypoadrenalism especially when hypercatecholaminemia remained.

Abstract
Adrenocorticotropic hormone (ACTH)-dependent Cushing syndrome is rarely caused by a pheochromocytoma. We present a case of a 46-year-old woman who developed severe hypertension, hypokalemia, and typical Cushingoid features. Investigations revealed extremely high metanephrine, cortisol, and ACTH levels. Imaging showed a 3.8-cm left adrenal mass. Preoperative control of hypertension and hypokalemia was very challenging. The patient was cured after surgical removal of the adrenal mass. We followed this by a review of the literature using the databases Google Scholar and PubMed. A total of 58 cases have been reported to date. In summary, ACTH-producing pheochromocytoma is a rare condition that poses a clinical challenge in the perioperative period. It is important that physicians be aware of such a condition because early recognition and treatment are crucial to decrease morbidity and mortality.

Abstract
BACKGROUND Ectopic hormone-secreting pheochromocytomas are rare; only case reports exist in the literature. This condition has been linked with increased malignancy, familial syndromes, and ACTH secretion. We wanted to test these hypotheses and shed light on the nature of ectopic hormone-secreting pheochromocytomas. METHODS This is a multicenter (francophone) observational study. Inclusion was based upon abnormal preoperative hormone tests in patients with pheochromocytoma that normalized after removal of the tumor. Where possible, immunohistochemistry was performed to confirm that ectopic secretion came from the tumor. RESULTS Sixteen cases were found: nine female and seven male patients. Median age was 50.5 (range 31-89) years. Most presented with hypertension, diabetes, or cushingoid features. Ten patients had specific symptoms from the ectopic hormone secretion. Two had a familial syndrome. Of eight patients with excess cortisol secretion, three died as a result of the tumor resection: two had pheochromocytomas >15 cm and their associated cortisol hypersecretion complicated their postoperative course. The other died from a torn subhepatic vein. The 13 survivors did not develop any evidence of malignancy during follow-up (median 50 months). Symptoms from the ectopic secretion resolved after removal of the tumor. Immunohistochemistry was performed and was positive in eight tumors: five ACTH, three calcitonins, and one VIP. CONCLUSIONS Most pheochromocytomas with ectopic secretion are neither malignant nor familial. Most ectopic hormone-secreting pheochromocytoma cause hypercortisolemia. Patients with a pheochromocytoma should be worked up for ectopic hormones, because removal of the pheochromocytoma resolves those symptoms. Associated cortisol secretion needs careful attention.

Abstract
Pheochromocytoma is a very special kind of tumor full of duplicity. On the one hand it represents its own microworld with unique clinical, biochemical and pathological features, while on the other it constitutes a tremendously significant part of whole body system, playing a vital role for practically every organ system. It has a very special character - sometimes like a child it can be sweet and predictable, while at times it can behave like a deadly wild beast, crashing and tearing everything on its path in a fierce rage. It also consists of the amazingly intelligent neuroendocrine cells that possess a magical ability to make miraculous substances of many kinds. But most of all, it is a system that is able to drive our curiosity and the itch of "Cogito, ergo sum" to limitless depths and year by year it still amazes us with new and unexpected discoveries that move our understanding of multiple pathways and metabolic events closer to the ultimate truth. Recent discoveries of succinate dehydrogenase (SHD) and prolyl hydroxylase (PHD) mutations, for example, propelled our understanding of neuroendocrine tumorigenesis as a whole, as well as physiology of mitochondrial respiratory chain and phenomenon of pseudohypoxia in particular. Good old discoveries make their way from dusty repositories to shine with new meaning, appropriate for the current level of knowledge. This acquired wisdom makes us better physicians - knowing the specific expression makeup of catecholamine transporters, GLUTs and SRIFs allows for better tailored imaging and therapeutic manipulations. There are still long ways to go, keeping in mind that pheochromocytoma is but so very special, and we are optimistic and expect many great things to come.

Abstract
We present a patient with a rare cause of ectopic ACTH-dependent Cushing's syndrome, caused by a pheochromocytoma. The case provides clues for a detailed discussion on the pitfalls and diagnostic difficulties in establishing the correct underlying cause of ACTH-dependent Cushing's syndrome. It clearly demonstrates that the relative contributions of clinical, biochemical, and radiological clues in establishing the correct underlying cause of Cushing's syndrome may differ considerably between Cushing's disease and Cushing's syndrome due to ectopic overproduction of ACTH. In addition, the literature concerning ACTH-producing pheochromocytomas is reviewed.

Abstract
Cushing's syndrome due to AdrenoCorticoTropic Hormone (ACTH)-secreting pheochromocytoma has been rarely reported during pregnancy and post-partum. We report the case of a 30-year-old woman who presented 3 months after delivery acute psychiatric signs and rapid progressive features of Cushing's syndrome. Hormonal tests confirmed ACTH-dependant Cushing's syndrome. A computed tomography scan revealed a 25 x 30 mm tumoral mass in the left adrenal gland and octreoscan scintigraphy showed only an uptake of the radiolabelled octreotide by the adrenal tumor. Fractionated 24-h urinary catecholamines and metanephrines were in the normal range, except for slightly increased adrenalin levels. A left laparoscopic adrenalectomy was performed with acute pulmonary oedema following the anesthesia. Histological examination revealed a 3.5 x 2.5 cm adrenal tumor consistent with a pheochromocytoma without signs of malignancy. The tumor cells immunostained for ACTH and diffuse hyperplasia of adrenocortical cells was observed. After surgery and short stay in intensive care unit, clinical and biological signs rapidly improved and both anti-hypertensive treatment and insulin injections were withdrawn. Genetic testing did not reveal germline mutations in RET protooncogene, Von Hippel Lindau and succinate deshydrogenase genes.

Abstract
A 42-year old woman presented with headache, palpitation and facial flushing. Ultrasonograms and computed tomograms revealed tumors in both of the adrenal glands, anterior aspect of the inferior vena cava, and the right lobe of the thyroid gland. Fine needle aspiration biopsy of the thyroid nodule revealed papillary thyroid carcinoma. Serum calcitonin, CEA, intact PTH and calcium levels were within normal limits. Markedly elevated levels of urinary normetanephrine and vanillylmandelic acid, and the result of 131I-metaiodobenzylguanidine (131I-MIBG) scintigraphy indicated that both adrenal masses were pheochromocytoma. Bilateral adrenalectomy, paracaval mass removal and total thyroidectomy together with central lymph node dissection were performed. The final pathological diagnosis was bilateral adrenal pheochromocytoma, paraganglioma, papillary thyroid carcinoma and either parathyroid adenoma or hyperplasia. Analysis of the RET proto-oncogene mutation, von Hippel Lindau mutation, succinate dehydrogenase subunit B mutation, and succinate dehydrogenase subunit D mutation yielded negative results. The relationship of these lesions could not be determined. This is the first report of a combination of bilateral pheochromocytoma, abdominal paraganglioma, papillary thyroid carcinoma and either parathyroid adenoma or hyperplasia without hyperparathyroidism.

Abstract
Apresentamos a experiência do Hospital das Clínicas da FMUSP, com o diagnóstico clínico, laboratorial e topográfico e com o tratamento do feocromocitoma. Embora novos testes bioquímicos, como as determinações de metanefrinas plasmáticas, tenham maior sensibilidade no diagnóstico desse tumor, testes mais disponíveis, como as determinações de metanefrinas urinárias e catecolaminas plasmáticas e urinárias ainda demonstram grande valor no diagnóstico. Eventuais falso-negativos e falso-positivos podem ser identificados com os testes de estímulo e depressão e com a exclusão do uso de droga. A ressonância magnética é o método mais sensível na identificação topográfica do tumor. O tratamento do tumor, exceto quando houver contraindicações, é sempre cirúgico e deve ser precedido pelo tratamento clínico. A identificação desse tumor é de fundamental importância no sentido de se prevenir a ocorrência de eventos com alta morbidade e mortalidade, bem como na identificação de outras síndromes neoplásicas que podem estar associadas a ele.

Abstract
Ectopic POMC syndrome remains one of the most challenging differential diagnoses in endocrinology. Recent progress in the understanding of the tissue specific regulation of POMC gene expression and new insights into the processing of the POMC peptide in nonpituitary tissues has helped elucidate some of the molecular events leading to ectopic expression and secretion of POMC peptides. Corticotropin and other POMC-derived peptides have diverse effects on adrenal steroidogenesis, growth, and extra-adrenal tissues. Differences in POMC gene regulation in the corticotrope versus ectopic POMC-producing tumors provides a scientific framework for the clinical distinction between eutopic and ectopic Cushing's syndrome. In an attempt to revisit recent basic and clinical advances in the diagnosis of ectopic POMC syndrome the authors undertook an extensive literature review of 530 cases in 197 published papers and provided a molecular biologic, demographic and diagnostic update. According to this review, the four most common causes of ectopic POMC syndrome are the small cell carcinoma of the lung (27%), bronchial carcinoids (21%), islet cell tumor of the pancreas (16%), and thymic carcinoids (10%). Although the clinical features of patients with ectopic POMC syndrome are similar to those with Cushing's disease, subgroup analysis reveals a broad spectrum of severity and progression of signs and symptoms of hypercortisolism. The endocrine workup of a patient with suspected ectopic POMC syndrome includes the establishment of pathologic hypercortisolism, diagnosis of corticotropin dependency, and the differential diagnosis of corticotropin-dependent Cushing's syndrome. The use of a variety of baseline endocrine values, dynamic endocrine testing, and invasive procedures leads to the correct diagnosis in the majority of patients with ectopic POMC syndrome. Diagnostic imaging, including conventional radiological techniques and somatostatin receptor scintigraphy, aids in the correct localization and eventual treatment of ectopic POMC production.

Abstract
Pheochromocytomas are endocrine tumors arising from chromaffin cells (pheochromocytes) of the adrenal glands in dogs and cats. The clinical symptomatology produced results from the direct presence and space-occupying nature of the tumor, or the secondary presence of excessive amounts of excreted catecholamines. Diagnosis and management of pheochromocytomas remain great challenges for veterinary clinicians. The diagnosis is based on the results of supporting routine lab evaluation, blood-pressure determinations, selected biochemical and pharmacologic tests, and a number of imaging techniques. Surgical extirpation continues to be the only definitive treatment for the pheochromocytoma. Medical therapy is used to stabilize the metabolic and cardiovascular states of the patient in a preoperative and surgical setting as well as to manage chronic long-term effects of excess catecholamines in patients with inoperable or metastatic disease.

Abstract
OBJECTIVE To report the occurrence of hypokalemia in a patient with pheochromocytoma. METHODS We present a case report and discuss the possible role of hyperepinephrinemia as a cause of hypokalemia. RESULTS A patient with pheochromocytoma had hypokalemia associated with vomiting, but hypokalemia recurred after repletion of potassium and cessation of vomiting. She had substantially increased epinephrine concentrations in the plasma and in the subsequently excised pheochromocytoma. Because evidence has shown that infusions of epinephrine induce hypokalemia in normal human subjects, the relationship between serum potassium and plasma epinephrine concentrations in 16 previous patients with pheochromocytoma and 4 patients with primary hyperepinephrinemia was studied. A significant negative correlation was noted. CONCLUSION The presence of hypokalemia and its potential role in predisposing to arrhythmias in patients with pheochromocytoma merit further study.

Abstract
BACKGROUND Operative management of pheochromocytomas dictates resection of the involved adrenal and exploration-resection of the contralateral gland if enlarged. We describe an exception to this rule. METHODS We report the largest series of patients with adrenocorticotropic hormone (ACTH)-secreting pheochromocytomas and review the world literature. RESULTS Four patients presented with findings of adrenocorticoid and catecholamine excess, as well as elevated levels of plasma ACTH, urinary metanephrines, and urinary free cortisol. Abdominal computed tomography scans revealed bilateral adrenal hyperplasia, and magnetic resonance imaging scans showed a unilateral adrenal mass with a bright T2 signal suggesting a pheochromocytoma. Two patients underwent adrenal venous sampling localizing ACTH secretion to the pheochromocytoma. All underwent unilateral adrenalectomy for a benign tumor without morbidity or death, leaving the contralateral hyperplastic adrenal in situ. After operation all patients experienced normalization of their levels of plasma ACTH, urinary metanephrines, and urinary free cortisol with resolution of symptoms. Combining our series with previously reported cases of ACTH-secreting pheochromocytomas, almost all are benign (20 of 21), in contrast to most ACTH-secreting tumors. CONCLUSIONS ACTH-secreting pheochromocytomas are the exception to the rule; unilateral adrenalectomy is curative and the contralateral hyperplastic adrenal can be preserved. This approach results in resolution of both syndromes of hormone excess and preserves long-term adrenal function.

Abstract
ACTH-independent Cushing's syndrome (CS) usually results from a solitary adrenocortical adenoma. We recently encountered a patient with ACTH-independent CS associated with bilateral adrenal enlargement. The evaluation led us to consider some rare but interesting entities. The patient was a 69 year-old woman who had a 10-15 year history of controlled hypertension, back pain associated with osteoporosis, easy bruising, and truncal obesity. Her medications included conjugated estrogens. Physical examination revealed classical features of CS. She had a raised blue lesion on her buccal mucosa. Plasma cortisol concentrations were elevated at 36 (a.m.) and 38 (p.m.) microg/dL. Urinary free cortisol was normal at baseline (65 microg/24 hours) but failed to suppress adequately in response to the low-dose dexamethasone suppression test (75 microg/24 hours). The plasma ACTH concentration was undetectable. Plasma cortisol concentrations failed to suppress (37 microg/dL) with an 8 mg overnight dexamethasone test. A CT scan of the abdomen revealed bilateral adrenal masses. The possibilities of food-induced CS and primary pigmented nodular adrenal disease were excluded by a lack of marked stimulation in cortisol secretion to a mixed-meal and dermatologic confirmation of the buccal mucosa lesion as an angioma and not a blue nevus. Adrenal venous sampling showed cortisol secretion from both adrenals. The patient underwent bilateral adrenalectomy with pathology confirming bilateral adenomas. This case illustrates an unusual application of selective venous sampling in the CS evaluation and raises questions about the pathogenesis of cortisol-secreting adrenocortical adenomas.

Abstract
Pheochromocytoma, although rare, is associated with a high degree of morbidity and mortality if not recognized. A high degree of suspicion in patients with new-onset hypertension; hypertension with sudden worsening or development of diabetes mellitus; or a family history of MEN, neuroectodermal tumors, or simple pheochromocytoma should prompt biochemical confirmation with either 24-hour urine catecholamines (norepinephrine and epinephrine) or total MET (NMET plus MET). Following confirmation of the diagnosis, radiologic studies with CT and (if needed) MIBG are employed to localize the tumor. Surgical removal is the only definitive therapy. Medical management with alpha-blocking agents, to control symptoms and prevent a hypertensive crisis, is generally advocated for 2 weeks preoperatively and intraoperatively. Occasionally, beta-blockers, employed only after adequate alpha-blockade, are necessary to control tachycardia and tachyarrhythmias. High-dose MIBG and combination chemotherapy have been used adjunctively to treat malignant pheochromocytoma, although neither modality provides lasting satisfactory results. Normal urine assays performed 2 weeks postoperatively ensure the complete removal of all tumor. Additionally, lifelong follow-up (yearly initially) is necessary to detect any signs of benign recurrence or malignancy because these have been reported to occur as long as 41 years after the initial surgical resection. Biochemical evidence of excess catecholamine production usually precedes the clinical manifestations of catecholamine excess when these tumors recur.

Abstract
Seven adrenal carcinomas and seventeen pheochromocytomas (PHs), two of which were clinically associated with a Cushing's syndrome and one associated with multiple endocrine neoplasia Type II (MEN-II), were investigated immunohistologically with a panel of antibodies against intermediate filament proteins, a proliferation-associated nuclear antigen (Ki-67), neuroendocrine tumor markers, and different hormones on paraffin-embedded tissue sections and, from 19 cases, also on frozen tissue sections. Synaptophysin proved to be the most reliable tumor cell marker on both snap-frozen and paraffin-embedded tissue but, like antibodies against NSE, yielded unspecific stainings in the carcinomas. The two Cushing-associated pheochromocytomas (CaPH) showed the same immunohistological profile as the other PHs, except one chromogranin-negative tumor. Five PHs showed weak reactivity for calcitonin, one for serotonin, and two for a-HCG in small amounts. All PHs lacked other hormone expression, including ACTH. The average growth fraction was small (2.2%) in 13 cases, but 80% of the tumor cells were proliferating in one case of CaPH. Adrenal carcinomas showed only weak or no expression of keratin in one case, a homogenous or droplet, non-filamentous cytoplasmic staining with antibodies against neurofilament in frozen tissue section, and they were completely chromogranin-negative. The average growth fraction was 7.6% in 5 cases.

Abstract
In order to delineate putatively coexisting dysregulations between sympathoadrenal system and hypothalamic-pituitary-adrenal (HPA)-axis during depression, the authors measured the following: the pre and postdexamethasone (1 mg) 24 hr urine excretion of noradrenaline, dopamine, adrenaline, 3-methoxy-4-hydroxyphenylglycol (MHPG), free cortisol (UFC), and plasma cortisol. Melancholic patients were characterized by a significantly higher excretion of noradrenaline, dopamine and adrenaline, combined with significantly increased UFC, postdexamethasone plasma cortisol, and UFC values. We found significant and positive correlations between UFC on the one hand, and the 24hr urine excretion of noradrenaline, dopamine, and adrenaline, on the other. By the same token, we established significant relationships between the 24 hr urine excretion of those catecholamines and the postdexamethasone UFC and plasma cortisol values. Cortisol nonsuppressors exhibited a significantly higher excretion of noradrenaline, dopamine and adrenaline, as compared with cortisol suppressors. Dexamethasone administration did not have a significant effect on the urinary output of noradrenaline, dopamine, adrenaline or MHPG.

Abstract
Cushing's syndrome is rare with only 20% of patients having a primary adrenal cause of hypercortisolism. We have developed a strategy to evaluate patients with suspected Cushing's syndrome and to localize the pathologic condition responsible for the hypercortisolism. This report reviews the last 11 consecutive patients who had a primary adrenal cause of hypercortisolism. Each patient had elevated 24-hour urine free cortisol and 17-hydroxycorticosteroid excretion consistent with hypercortisolism. All but one patient had undetectable plasma ACTH levels. No patient suppressed urinary steroid levels with high-dose dexamethasone and only one patient increased plasma ACTH or cortisol levels with oCRH, findings that were consistent with a pituitary-independent form of hypercortisolism. No patient had a pituitary tumor detected by computed tomography or magnetic resonance imaging, and eight patients had adrenal tumors accurately imaged. MRI of the adrenal glands correctly diagnosed adenoma in 5 of 6 patients with adenomas, carcinoma in 1 patient, and ACTH-producing pheochromocytoma in 1 patient. One tumor classified as carcinoma by MRI appeared on pathologic examination to be an adenoma. Three patients underwent petrosal sinus sampling for measurement of ACTH before and after oCRH administration, and each had petrosal sinus ACTH levels equal to peripheral levels, consistent with a primary adrenal cause of hypercortisolism. Two of these patients had typical bilateral pigmented micronodular adrenocortical disease and the third patient had macronodular adrenocortical hyperplasia. Each of the 11 patients was cured of hypercortisolism by unilateral or bilateral adrenalectomy and no patient has developed recurrent disease during the 7 to 29 month follow-up period. New modalities including the ovine CRH test, MRI, and petrosal sinus sampling have improved the evaluation of certain patients with Cushing's syndrome.

Abstract
Bilateral inferior petrosal sinus sampling was successfully performed in 12 of 13 consecutive patients with ACTH-dependent Cushing's syndrome. Ten of the patients subsequently had transsphenoidal pituitary microsurgery. Eight patients in whom the inferior petrosal sinus to peripheral vein ACTH level ratio was 1.5 or greater were found to have a pituitary adenoma. One of the remaining two patients who had ratios less than 1.5 had pituitary hyperplasia while the other had no identified abnormality. In five of the patients with pituitary tumour a ratio above 1.5 was present on only one side. Bilateral petrosal sampling is therefore always necessary. Tumour localization within the pituitary was only poorly predicted by either petrosal sinus sampling (four of eight) or computed tomography scanning (three of eight). If petrosal sinus sampling is used early in the differential diagnosis of ACTH-dependent hypercortisolism, then the use of other differential diagnostic tests may not always be necessary.

Abstract
Two female patients with functioning adrenocortical carcinomas had plasma ACTH detectable by RIA at presentation. In both patients there was evidence for biological activity of ACTH. There was no evidence for an ectopic source of ACTH, nor for a pituitary tumour. Urinary steroid analysis showed patterns of multiple hormone secretion characteristic of adrenocortical carcinomas. The finding of detectable ACTH concentrations in a patient with Cushing's syndrome does not exclude the presence of an adrenocortical tumour.

Abstract
The circadian blood pressure rhythm was compared in patients with Cushing's syndrome, essential hypertension, and primary aldosteronism. In patients with essential hypertension or primary aldosteronism, a clear nocturnal fall in systolic and diastolic blood pressure and heart rate was observed. This fall was seen in untreated subjects as well as in patients receiving combined treatment with a calcium antagonist, diuretic, converting enzyme inhibitor, alpha-blocker and beta-blocker, or sympatholytic drug. In these groups, there was a positive correlation between heart rate and systolic or diastolic blood pressure. On the other hand, in patients with Cushing's syndrome, there was no nocturnal fall in blood pressure but in some patients a rise was observed. In all patients there was a nocturnal fall in heart rate. Thus, there was no significant correlation between heart rate and blood pressure in these patients. Exogenous glucocorticoid eliminated the normal nocturnal fall of blood pressure in patients with chronic glomerulonephritis or systemic lupus erythematosus. These results suggest that the changed circadian blood pressure pattern in patients with Cushing's syndrome is not due to antihypertensive treatment or to the mineralocorticoid excess accompanying this disease, but it is attributable to excess glucocorticoid or the associated disturbance in the adrenocorticotropic hormone-glucocorticoid system (or both). This conclusion also implies that the normal circadian rhythm of blood pressure may be regulated at least in part by the adrenocorticotropic hormone-glucocorticoid system.

Abstract
The results of histopathological, histochemical and ultrastructural investigations on pheochromocytomas and paragangliomas have been reported. These results allowed the functional identification of the cell types composing many of such tumours. Moreover, comparison of these data with clinico-pathologic findings outlined the advantages and limits of cytologic studies for understanding the natural history of pheochromocytomas and paragangliomas and improving our diagnostic and prognostic criteria.

Abstract
Two patients who had removal of seemingly benign pheochromocytomas had recurrences 10 and 14 years later despite normal catecholamine excretion for 7 and 9 years postoperatively. The first patient returned with a myocardial infarction and an apparently solitary recurrence; the second patient with a stroke and metastatic disease. Both patients had recurrence of hypertension and increased catecholamine excretion. They were given phenoxybenzamine and are doing satisfactorily 7 and 9 years after their recurrences. Such patients should be followed after surgery for 15 or more years for early detection of recurrences. Prompt therapy should reduce the risk of undesirable complications.

Abstract
A woman with sustained hypertension, facial roundness, hirsutism, marked sweating, and generalized tremor was found to have a right adrenal pheochromocytoma. Elevated levels of serum cortisol, plasma ACTH, and serum catecholamines returned to normal after the tumor was removed. It was confirmed that enzymatically dispersed tumor cells produced ACTH and catecholamines concomitantly during in vitro incubation.

Abstract
Our patient had a left suprarenal mass. His blood pressure was normal, but his urinary catecholamines (CA), vanillylmandelic acid (VMA), total metanephrines (TMn) and 5-hydroxyindolacetic acid (5HIAA) were elevated. In addition, he had elevated, nonsuppressible urinary 17-ketosteroids (17KS) and androsterone, but his urinary 17-hydroxycorticoids (17OHCS) and free cortisol were normal, as were his plasma cortisol and ACTH. After resection of the suprarenal mass, the patient's urinary hormone values reverted to normal. The mass contained a pheochromocytoma and an adrenocortical adenoma. The pheochromocytoma was unusual in that it contained very little norepinephrine (NE) and dopamine (DA) and an abundance of epinephrine (E) despite normal enzyme concentrations. Electron micrographs showed primarily E granules with few of the NE-type. The immunoperoxidase histochemical stains for vasoactive intestinal peptide (VIP) and serotonin (S) were strongly positive. The patient's blood pressure may have been normal because his pheochromocytoma secreted E, VIP, or S. The associated adrenocortical adenoma produced no symptoms and was probably coincidental.

Abstract
High plasma concentrations of neuropeptide Y (NPY) were found in a patient with bilateral adrenal phaeochromocytomas and medullary thyroid carcinoma associated with MEN IIa (32 pmol/l, normal less than 3.5 pmol/l). Both adrenal tumours contained and secreted NPY. Manipulation at operation produced a remarkable increase in plasma NPY concentrations (peak = 1631 pmol/l) coinciding with increases in plasma levels of catecholamines and arterial pressure. NPY was also shown to be present in thyroid tumour tissue: the concentration of NPY in tumour was 50-fold higher (0.9 nmol/g vs 0.004 nmol/g) than in adjacent normal thyroid tissue. It is possible that NPY from some phaeochromocytomas may contribute to hypertension during surgery.

Abstract
A patient is described with Cushing's syndrome owing to a pheochromocytoma that was producing adrenocorticotropic hormone. Preoperative diagnosis was suggested by finding bilateral adrenocortical hyperplasia plus a separate unilateral adrenal medullary mass and was confirmed laboratory studies. Proper preoperative preparation was followed by a unilateral adrenalectomy and a clinical cure of both conditions. Immunohistochemical studies confirmed the ectopic production of adrenocorticotropic hormone and its related peptides more thoroughly than previous reports. The hormone production appeared clinically and immunocytochemically to resemble pituitary Cushing's disease more closely than ectopic production of adrenocorticotropic hormone by other tumors. The clinical aspects of this case illustrate the importance of proper preoperative recognition to reduce the high known percentage of morbidity and mortality.

Abstract
Phaeochromocytomas are uncommon among patients with hypertension, and sometimes occur in persons without known hypertension, but are important to detect because they are often lethal but commonly curable, and because they are a clue to the presence of associated conditions. Paroxysmal symptoms (especially headache, palpitations, diaphoresis and anxiety), hypertension that is intermittent, unusually labile or resistant to conventional therapy, and conditions known to be associated raise the clinical suspicion of phaeochromocytoma. Biochemical confirmation is commonly achieved by measurement of urinary catecholamines, metanephrines or VMA. Plasma noradrenaline and adrenaline measurements may be superior to measurements of urinary catecholamine metabolites, but strict attention to the details of sample collection, handling and storage, the many sources of possible biological variation and the effects of drugs is critical if diagnostic error is to be avoided. Patients should be evaluated in the drug-free state if at all possible. Anatomical localization, in the abdomen in the vast majority of cases and usually in the adrenal medullae, can generally be accomplished with computed tomographic scans. Bilateral adrenomedullary tumours are the rule in familial phaeochromocytoma. Most phaeochromocytomas are benign and can be excised totally after medical preparation with an alpha-adrenergic antagonist.

Abstract
An autopsy case of a 54-year-old woman with malignant pheochromocytoma and ectopic ACTH production was reported. Noradrenaline was increased in 24 hour urine and in the blood sample from the left adrenal vein. Hormone assay studies of the tumor tissue and plasma revealed abnormally high levels of ACTH. Formaldehyde fume induced fluorescence method demonstrated biogenic amine in the tumor cytoplasm. Electron microscopic examinations also disclosed numerous neurosecretory granules in the tumor cytoplasm. These findings confirmed that this pleomorphic carcinoma of the left adrenal gland was one of the APUDoma originating from the adrenal medulla, so-called pheochromocytoma.

Abstract
Two patients with metastatic pheochromocytoma received chemotherapy with 5-fluorouracil, cyclophosphamide, and streptozotocin. A biochemical response occurred in one instance. A review of the literature and the results in the reported patients indicate cyclophosphamide and/or streptozotocin may have activity in this neoplasm.

Abstract
The concentration of epinephrine, norepinephrine, dopamine, met-enkephalin-, ACTH-, calcitonin- and somatostatin-like immunoreactivity (IR) were determined in the extracts of 9 adrenal pheochromocytomas from 7 patients. Six of these patients had Sipple's syndrome. There was a close correlation between the amounts of met-enkephalin-IR and of epinephrine present in the tumor tissue (p less than 0.01). Such a correlation was not found between catecholamines and the other polypeptide hormones investigated. The relevance of the close parallel in the occurrence of met-enkephalin-IR and epinephrine in human adrenal pheochromocytoma tissue is unknown, but it underlines earlier observations in the normal bovine and rat adrenal medulla on a co-storage and co-release of these substances in normal circumstances.

Abstract
Hyperadrenalism in childhood and adolescence has unique features that influence diagnosis and management. We reviewed our experience with 18 patients, ranging in age from 18 months to 18 years. Nine had bilateral adrenal hyperplasia, eight had adrenal neoplasms, and one had micronodular hyperplasia. Patients with congenital adrenal hyperplasia and hyperaldosteronism were excluded. Six patients with Cushing's disease diagnosed in earlier years were treated by total adrenalectomy and recently two patients underwent transsphenoidal removal of pituitary tumors. Bilateral adrenalectomy was carried out in one patient with micronodular hyperplasia and in a second because of elevated adrenocorticotrophic hormone (ACTH) levels from an undefined source. Eight patients had adrenal neoplasms, including five adenomas and three carcinomas. We found no reliable criteria to differentiate before surgery between adrenal adenomas and adrenal carcinomas. The most recognizable characteristic of malignancy was tumor size, specifically weight greater than 75 gms. Of the three patients with adrenal carcinoma, one expired 20 months after adrenalectomy and 8 months after receiving palliative partial hepatectomy for liver metastasis. Two patients are well with normal growth and development at 11 and 20 years following adrenalectomy. With the exception of one patient who died 6 years after surgery from a glioblastoma multiforme, all patients with adrenal adenomas are well. Eight patients underwent bilateral adrenalectomy for hypercortisolism. Five of the six who have reached their adult stature are significantly stunted. Four of six patients with Cushing's disease, treated by total adrenalectomy, have developed Nelson's syndrome at 2, 6, 10, and 12 years after surgery. Of the two patients undergoing transsphenoidal surgery, one had recurrent disease at 2 years and was treated by pituitary irradiation with recovery. The patients undergoing adrenalectomy for micronodular hyperplasia and ectopic ACTH are well at 2 and 4 years, respectively. Cushing's disease in children and adolescents is best treated by transsphenoidal removal of the pituitary adenoma. Adrenalectomy, once the most accepted approach, plays a secondary role and is indicated primarily in micronodular adrenal hyperplasia, in patients with ectopic ACTH production of an undefined source, and in recurrent Cushing's disease following prior pituitary irradiation. The high incidence of Nelson's syndrome in children treated by adrenalectomy mandates that patients at risk be monitored lifelong for the progression of a pituitary tumor.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
A 47-year old woman is presented who had a left adrenal pheochromocytoma with manifestations also indicative of ectopic ACTH syndrome. The excised adrenal gland showed both an adrenal medullary tumor and adrenal cortical hyperplasia. Immunostaining also showed the presence in the tumor of ACTH and beta endorphins. The immediate post-adrenalectomy decline of catecholamines, ACTH, cortisol and beta endorphins indicate that the adrenal itself was the source of these hormones. This patient, the thirteenth now reported in the literature, represents one form of ectopic ACTH syndrome in which the lesion is benign, and in which a successful outcome can be anticipated.

Abstract
The multiple endocrine neoplasia (MEN) syndromes are characterized by autosomal dominant inheritance with a high degree of penetrance but varying expression. This review gives a classification of these syndromes and a short summary of the historical background. The pathogenesis of the disease and its possible origin in the APUD cell system are discussed together with the mechanisms underlying normal and ectopic hormone production by MEN tumors on the basis of recent findings in molecular endocrinology. The natural history and the clinical manifestations of the different syndromes are described. The sensitivity and discriminative capacity of the tests used to detect the syndromes in an early stage are compared. The choice of therapy and criteria for the timing and extensiveness of treatment are also considered. Lastly, problems associated with the ethical and legal aspects of screening, central registration, and monitoring of relatives at risk are described.

Abstract
A 35-year-old man with Cushing's syndrome due to ectopic ACTH production is described. The six-week history and severe proximal myopathy were highly suggestive of a malignant tumour, but a solitary phaeochromocytoma of the left adrenal gland was the source of ACTH production. The surgical outcome was successful and three months post-operatively the hypothalamic-pituitary-adrenal axis was normal. At 12 months follow-up he remains well with complete regression of the features of Cushing's syndrome.
