Steroid profiling in adrenal disease.

The measurement of steroid hormones in blood and urine, which reflects steroid biosynthesis and metabolism, has been recognized as a valuable tool for identifying and distinguishing steroidogenic disorders. The application of mass spectrometry enables the reliable and simultaneous analysis of large panels of steroids, ushering in a new era for diagnosing adrenal diseases. However, the interpretation of complex hormone results necessitates the expertise and experience of skilled clinicians. In this scenario, machine learning techniques are gaining worldwide attention within healthcare fields. The clinical values of combining mass spectrometry-based steroid profiles analysis with machine learning models, also known as steroid metabolomics, have been investigated for identifying and discriminating adrenal disorders such as adrenocortical carcinomas, adrenocortical adenomas, and congenital adrenal hyperplasia. This promising approach is expected to lead to enhanced clinical decision-making in the field of adrenal diseases. This review will focus on the clinical performances of steroid profiling, which is measured using mass spectrometry and analyzed by machine learning techniques, in the realm of decision-making for adrenal diseases.

Rare Coexistence of Aldosterone-producing Adrenocortical Adenoma Confirmed by an Immunohistochemical Analysis of Steroidogenic Enzymes with Adrenal Ectopic Thyroid Tissue: A Case Report and Literature Review.

A 56-year-old man presented with a history of hypertension; clinically, the patient had primary aldosteronism (PA) and a 4-cm left adrenal tumor. The left adrenal glands, resected by adrenalectomy, also contained ectopic thyroid tissue (ETT). An immunohistochemical analysis of steroid-converting enzymes revealed an aldosterone-producing adenoma (APA). Among 19 previously reported cases of adrenal ETT, 4 had adrenal hormonal abnormalities, all of which were PA. This is the first case of adrenal ETT coexisting with APA, confirmed by steroid-converting enzyme expression. Further analyses using cumulative case data are required to clarify the correlation between adrenal ETT and APA.

Treating Primary Aldosteronism-Induced Hypertension: Novel Approaches and Future Outlooks.

Primary aldosteronism (PA) is the most common cause of secondary hypertension and is associated with increased morbidity and mortality when compared with blood pressure-matched cases of primary hypertension. Current limitations in patient care stem from delayed recognition of the condition, limited access to key diagnostic procedures, and lack of a definitive therapy option for nonsurgical candidates. However, several recent advances have the potential to address these barriers to optimal care. From a diagnostic perspective, machine-learning algorithms have shown promise in the prediction of PA subtypes, while the development of noninvasive alternatives to adrenal vein sampling (including molecular positron emission tomography imaging) has made accurate localization of functioning adrenal nodules possible. In parallel, more selective approaches to targeting the causative aldosterone-producing adrenal adenoma/nodule (APA/APN) have emerged with the advent of partial adrenalectomy or precision ablation. Additionally, the development of novel pharmacological agents may help to mitigate off-target effects of aldosterone and improve clinical efficacy and outcomes. Here, we consider how each of these innovations might change our approach to the patient with PA, to allow more tailored investigation and treatment plans, with corresponding improvement in clinical outcomes and resource utilization, for this highly prevalent disorder.

High Filamin a Expression in Adrenocortical Carcinomas Is Associated with a Favourable Tumour Behaviour: A European Multicentric Study.

The insulin-like growth factor 2 (IGF2) promotes cell growth by overactivating the IGF system in an autocrine loop in adrenocortical carcinomas (ACCs). The cytoskeleton protein filamin A (FLNA) acts as a repressor of IGF2 mitogenic signalling in ACC cells. The aims of this study were to test FLNA expression by immunohistochemistry in 119 ACCs and 26 adrenocortical adenomas (ACAs) and to evaluate its relationship with clinicopathological features and outcome in ACCs. We found that 71.4% of ACCs did not express FLNA, whereas FLNA absence was a rare event in ACAs (15.4%, p < 0.001 vs. ACCs). In addition, the expression of FLNA was associated with a less aggressive tumour behaviour in ACCs. Indeed, the subgroup of ACCs with high FLNA showed a lower ENSAT stage, Weiss score, and S-GRAS score compared to ACCs with low FLNA expression (p < 0.05). Moreover, patients with high FLNA had a longer overall survival than those with low FLNA (p < 0.05). In conclusion, our data suggest that FLNA may represent a "protective" factor in ACCs, and the integration of FLNA immunohistochemical expression in ACC tissues along with other clinical and molecular markers could be helpful to improve diagnostic accuracy and prognosis prediction in ACCs.

Bilateral co-secretory lesions presenting with coexisting Cushing syndrome and primary aldosteronism: a case report.

BACKGROUND: There is an increasing number of cases of aldosterone- and cortisol-producing adenomas (A/CPAs) reported in the context of primary aldosteronism (PA). Most of these patients have PA complicated with subclinical Cushing's syndrome; cases of apparent Cushing's syndrome (CS) complicated with aldosteronism are less reported. However, Co-secretory tumors were present in the right adrenal gland, a cortisol-secreting adenoma and an aldosterone-producing nodule (APN) were present in the left adrenal gland, and aldosterone-producing micronodules (APMs) were present in both adrenal glands, which has not been reported. Here, we report such a case, offering profound insight into the diversity of clinical and pathological features of this disease. CASE PRESENTATION: The case was a 45-year-old female from the adrenal disease diagnosis and treatment centre in West China Hospital of Sichuan University. The patient presented with hypertension, moon-shaped face, central obesity, fat accumulation on the back of the neck, disappearance of cortisol circadian rhythm, ACTH < 5 ng/L, failed elevated cortisol inhibition by dexamethasone, orthostatic aldosterone/renin activity > 30 (ng/dL)/(ng/mL/h), and plasma aldosterone concentration > 10 ng/dL after saline infusion testing. Based on the above, she was diagnosed with non-ACTH-dependent CS complicated with PA. Adrenal vein sampling showed no lateralization for cortisol and aldosterone secretion in the bilateral adrenal glands. The left adrenocortical adenoma was removed by robot-assisted laparoscopic resection. However, hypertension, fatigue and weight gain were not alleviated after surgery; additionally, purple striae appeared in the lower abdomen, groin area and inner thigh, accompanied by systemic joint pain. One month later, the right adrenocortical adenoma was also removed. CYP11B1 were expressed in the bilateral adrenocortical adenomas, and CYP11B2 was also expressed in the right adrenocortical adenomas. APN existed in the left adrenal gland and APMs in the adrenal cortex adjacent to bilateral adrenocortical adenomas. After another surgery, her serum cortisol and plasma aldosterone returned to normal ranges, except for slightly higher ACTH. CONCLUSIONS: This case suggests that it is necessary to assess the presence of PA, even in CS with apparent symptoms. As patients with CS and PA may have more complicated adrenal lesions, more data are required for diagnosis.

Case series: Primary aldosteronism diagnosed despite normal screening investigations: A report of three cases.

RATIONALE: Since the introduction of the aldosterone-to-renin ratio (ARR) as a screening tool for primary aldosteronism (PA), there has been a marked increase in the reported prevalence of this condition among hypertensive, even normotensive, subjects. PATIENT CONCERNS: But ARR as a spot blood draw for estimating a patient's aldosterone secretory status is influenced by many factors. DIAGNOSES: Here, we describe a series of patients with biochemically confirmed PA, whose diagnosis was delayed by the initial ARR assessment with non-suppressed renin. INTERVENTIONS: Patient 1 had a history of resistant hypertension for many years and had a negative initial screening for secondary hypertension (including ARR). At the reevaluation, ARR was close to cutoff still with normal renin after strict and extended drug washout, and the further workup for PA demonstrated a unilateral aldosterone producing adenoma that was surgically removed, with subsequent complete biochemical remission and partial clinical success. Patient 2 was diagnosed with idiopathic hyperaldosteronism combined with obstructive sleep apnea syndrome, which could increase renin resulting in a negative ARR, and finally got a better treatment effect with PA-specific spironolactone, as well as continuous positive airway pressure. Patient 3 with hypokalemia as the main presentation was finally diagnosed with PA after excluding other diseases, and proceeded to laparoscopic adrenalectomy and histologically confirmed an aldosterone producing adenoma. Postoperatively, patient 3 achieved complete biochemical success without any medicine. OUTCOMES: The clinical status of all three patients was effectively managed, resulting in either complete resolution or notable improvement of their respective conditions. LESSONS: After rigorous standardized diagnostic evaluation, there are still many reasons for ARR negative in PA, but they all basically occur in the background of normal or normal-high renin without suppression. A negative screening test result should be repeated and analyzed carefully if this is not consistent with the clinical picture. If, despite a repeatedly negative ARR, clinical suspicion remains high, we recommend consideration of further evaluation, including confirmatory tests and adrenal venous blood sampling (AVS) or even 68Ga-pentixafor PET/CT to better confirm the diagnosis and improve patient outcomes.

Unique Case of Cardiomyopathy Secondary to Adrenal Adenoma (Primary-Aldosteronism).

INTRODUCTION: To our knowledge this is the first & only case report in India wherein primary aldosteronism (adrenal adenoma) presented with cardiomyopathy (regressed post-surgery). MATERIALS: First reported case in India. RESULT: Herein August 2018 IPGMER-SSKM-Kolkata 29-year female presented with 1-month exertional dyspnoea, occasional chest pain, sweating, fainting. On examination (Pulsus-bisferiens, forceful-well sustained-double-kicking-apex, grade-3-ejection-systolic-murmur (left 3rd intercostal space) (murmur intensity increased by Valsalva & standing). Left-ventricular-hypertrophy by ECG (R(I)+S(III) 35 mm) & Echocardiography (LVO Tobstruction, RWMA, wall-hypokinesia, systolic-anterior-motion, asymmetric-septal-hypertrophy excluded). Cardiac-MRI confirmed cardiomyopathy (patchy late gadolinium enhancements). She refused endomyocardial biopsy (normal troponin & NT-pro-BNP). Uncontrolled hypertension (BP 190/150) despite maximum Prazosin20 & Clonidine 100 dosage, besides persistent hypokalemia (despite repeated Intravenous KCL). With raised 24 hour Urine K + 52 meq/day raised TTKG 17.5, high serum AR Ratio (87.65) high Aldosterone (44.7) (normal Plasma Renin Activity (PRA 0.5) normal Cortisol (12.1). 24 x 22 x 15 mm hypodense mixed enhancing mass Left Adrenal in Contrast CT abdomen. Spironolactone 50, Ramipril 5, Ramipril5 subsequently added. Following unilateral adrenalectomy (histopathology 4 x 4 x 1 cm benign adrenal cortical adenoma) (without pleomorphism nor necrosis). (BP finally controlled before discharge following week. Patients cardiac function improved over next 6-months (complete regression of LVH in ECG-Echo & LGE in cardiac-MRI). Patient been regularly followed (till October 2022) at AIIMS-kalyani. Well controlled Hypertension (only Amlodipine 2.5 mg) (normal K + level, still in remission, normal potassium & normal cardiac function). CONCLUSION: Prior in-vitro studies suggested possible aldosterone (excess) induced direct activation of mineralocorticoid receptors in (low-density/serum-free) ventricular myocytes (culture); also aldosterone increases mRNA for cardiac-ANF & alpha/beta-myosin heavy-chains (aldosterone also effects collagen deposition & fibroblast proliferation). All of these were clearly prevented by adding spironolactone. References Higuchi S, Ota H, Tezuka Y, et al.

Food-dependent Cushing's syndrome due to unilateral adrenocortical adenoma with cortisol secretion without ACTH elevation detected in peripheral blood by the CRH test: a case report.

We report an extremely rare case of a 61-year old woman with food-dependent Cushing's syndrome (FDC) due to unilateral adrenocortical adenoma (UAA) with cortisol (CORT) secretion without ACTH elevation detected in peripheral blood by the CRH test. She was on oral medications for hypertension and depression, and presented weight gain, general fatigue, muscle weakness, and hypokalemia. Despite the fact that the diurnal variation of ACTH was always suppressed, a diurnal variation in CORT was observed, in the form of low levels in the early morning and high levels in the afternoon. An increase in CORT was shown in a 75 g-oral glucose tolerance test (OGTT) and in a mixed meal tolerance test, but no change in CORT levels was seen in intravenous glucose tolerance tests. Elevated CORT levels were observed in response to intravenous injection of CRH, although ACTH levels were always below the measured sensitivity. Laparoscopic left adrenalectomy was performed, which resulted in postoperative improvement in potassium and ACTH levels and disappearance of the CORT secretory response in the OGTT. Clear expression of glucose-dependent insulinotropic polypeptide receptor (GIPR), CRH and CRH receptor 2 (CRHR2) were confirmed in the surgically-resected UAA specimen by molecular and immunohistochemical analyses, suggesting the involvement of not only GIPR, but also CRH and CRHR2 in FDC.

Simplified urinary steroid profiling by LC-MS as diagnostic tool for malignancy in adrenocortical tumors.

OBJECTIVES: Preoperative identification of malignant adrenal tumors is challenging. 24-h urinary steroid profiling by LC-MS/MS and machine learning has demonstrated high diagnostic power, but the unavailability of bioinformatic models for public use has limited its routine application. We here aimed to increase usability with a novel classification model for the differentiation of adrenocortical adenoma (ACA) and adrenocortical carcinoma (ACC). METHODS: Eleven steroids (5-pregnenetriol, dehydroepiandrosterone, cortisone, cortisol, α-cortolone, tetrahydro-11-deoxycortisol, etiocholanolone, pregnenolone, pregnanetriol, pregnanediol, and 5-pregnenediol) were quantified by LC-MS/MS in 24-h urine samples from 352 patients with adrenal tumor (281 ACA, 71 ACC). Random forest modelling and decision tree algorithms were applied in training (n = 188) and test sets (n = 80) and independently validated in 84 patients with paired 24-h and spot urine. RESULTS: After examining different models, a decision tree using excretions of only 5-pregnenetriol and tetrahydro-11-deoxycortisol classified three groups with low, intermediate, and high risk for malignancy. 148/217 ACA were classified as being at low, 67 intermediate, and 2 high risk of malignancy. Conversely, none of the ACC demonstrated a low-risk profile leading to a negative predictive value of 100% for malignancy. In the independent validation cohort, the negative predictive value was again 100% in both 24-h urine and spot urine with a positive predictive value of 87.5% and 86.7%, respectively. CONCLUSIONS: This simplified LC-MS/MS-based classification model using 24-h-urine provided excellent results for exclusion of ACC and can help to avoid unnecessary surgeries. Analysis of spot urine led to similarly satisfactory results suggesting that cumbersome 24-h urine collection might be dispensable after future validation.

A Two-in-One Tumor in the Adrenal: A Functional Adrenocortical Adenoma with Myelolipomatous Differentiation.

BACKGROUND: Adrenocortical adenoma (ADA) and myelolipoma are two common benign neoplasms of the adrenal cortex that have been reported to occur together. CASE REPORT: A 14-year-old girl presented with the features of ACTH-independent endogenous Cushing syndrome. Abdominal CECT revealed a left adrenal 2.3 × 1.8 × 1.5 cm arterially enhancing nodular lesion with central hypodensity. Histologically, this was an ADA with oncocytic change and myelolipomatous differentiation/metaplasia. DISCUSSION/CONCLUSION: ADA with myelolipomatous differentiation/metaplasia can occur in the pediatric age group.

Node-by-node diagnosis for multiple ipsilateral nodules by segmental adrenal venous sampling in primary aldosteronism.

OBJECTIVES: In patients with primary aldosteronism (PA), multiple adrenocortical nodules may be present on the surgical side. The aim of this study was to clarify the pathological diagnosis and the node-by-node diagnostic capability of segmental adrenal venous sampling (sAVS). DESIGN: Retrospective study. PATIENTS: A total of 162 patients who underwent adrenalectomy following sAVS were studied. MEASUREMENTS: Multiple nodules on the surgical side were extracted while referring to contrast-enhanced computed tomography images. We also performed a detailed histopathological analysis of the resected specimens from patients undergoing sAVS, which included immunohistochemistry for CYP11B2. RESULTS: In 11 (6.8%) patients, two to three nodules were detected on the surgical side. All patients were diagnosed by sAVS with at least one aldosterone-producing adenoma (APA) for localized aldosterone elevation in tributaries. Seven patients showed a lateralization index value of ≥4 after ACTH stimulation. Histopathologically and clinically, two patients had two or three CYP11B2-positive APAs, and the other nine patients both APAs and non-APAs. The positive predictive value of the most suspected APA, that is, the drainer that showed the highest aldosterone level by sAVS, was 11/11 (100%, 95% confidence interval [CI]: 71.5%-100%), while that for the second and third suspected APA was 3/7 (42.9%, 95% CI: 9.9%-81.6%), and they were significantly different (p = .01). Further, the positive predictive value of non-APA was 4/4 (100%, 95% CI: 39.8%-100%). CONCLUSIONS: The sAVS could correctly diagnose the aldosterone production in multiple ipsilateral adrenal nodules.

Mixed ganglioneuroma and cortical adenoma in adrenal gland: A case report.

RATIONALE: Adrenal mixed corticomedullary tumors (MCMTs) are single tumor masses composed of an intimately admixed population of both adrenal cortical cells and medullary components. Most medullary tumor components are pheochromocytomas; however, MCMTs composed of ganglioneuroma and adrenal cortical adenoma are extremely rare. The current case is a rare case of adrenal MCMT composed of ganglioneuroma and adrenal cortical adenoma with primary aldosteronism. PATIENT CONCERNS: A 49-year-old male was admitted because of hypokalemia and an adrenal mass. He was diagnosed with hypertension in his 20s and was taking blood pressure medications. DIAGNOSIS: Plasma aldosterone concentration 376.5 pg/dL (normal 37.8~233.0 pg/mL) and potassium 2.8 mmol/L (normal 3.4~4.9 mmol/L) were detected. The aldosterone-to-renin ratio [the ratio of plasma aldosterone concentration (ng/dL) to PRA (ng/mL/hour)] was 38. The saline loading test showed that serum aldosterone (49.4 ng/dL) was not suppressed, compared with the basal level (28.4 ng/dL). The adrenal venous sampling test showed that the aldosterone level markedly increased to 1521.2 pg/mL. Abdominal computed tomography revealed an enlarged relatively well-circumscribed multinodular mass (35 × 13 × 30 mm) in the right adrenal gland. INTERVENTIONS: Laparoscopic right adrenalectomy was performed under the clinical diagnosis of a functioning adrenal cortical adenoma. OUTCOMES: After laparoscopic right adrenalectomy, the serum aldosterone and renin levels returned to normal. The patient maintained a normal aldosterone level without recurrence for 16 months. LESSONS: Adrenal MCMTs of the ganglioneuroma and cortical adenomas in the ipsilateral adrenal gland are extremely rare. Adrenal MCMTs exhibit benign clinical behavior, with no metastasis or death due to the tumor. With the development of diagnostic imaging technology, it is possible to identify mixed tumors. However, surgical resection of adrenal gland is a common treatment and a final diagnosis should be made based on the pathological results after surgery. Because this is to rule out the occurrence of rare malignant tumors and confirm the pattern of mixed tumors.

Left adrenal aldosteronism coexisting with left paraaortic paraganglioma presenting as bilateral adrenal and left paraaortic tumors- comprehensive adrenal evaluation aiding perfect management: a case report.

BACKGROUND: Coexistence of a catecholamine-secreting tumor and an adrenal cortical tumor is quite rare which makes both diagnosis and management challenging. The purpose of this article is to describe the presence of this condition, share a stepwise approach for preoperative evaluation, and review the related literature. CASE PRESENTATION: A 44-year-old male patient had a history of hypertension and aggravating hypokalemia for years. Abdominal computed tomography incidentally found concomitant bilateral adrenal and left para-aortic tumors. Comprehensive adrenal hormone tests revealed a high aldosterone renin ratio and mildly elevated 24-h urine vanillylmandelic acid and norepinephrine levels. Subsequently, a metaiodobenzylguanidine scan showed uptake over the left para-aortic tumor, and NP-59 adrenal scintigraphy showed uptake over the left adrenal tumor. Further confirmatory tests, including captopril suppression, irbesartan suppression, and saline infusion, all confirmed the diagnosis of hyperaldosteronism. Adrenal venous sampling following 2 months of preparation with an alpha blocker demonstrated a left aldosterone-producing adrenal adenoma. Combining hormonal analysis, imaging studies, and adrenal venous sampling, the patient was diagnosed with left adrenal aldosteronoma, right adrenal nonfunctional tumor, and left para-aortic paraganglioma (PGL). Accordingly, laparoscopic left adrenalectomy and left PGL excision were performed smoothly under alpha blocker maintenance. The pathology report confirmed left adrenal cortical adenoma and left para-aortic PGL. Postoperatively, the blood pressure, biochemical tests, and adrenal hormone assays returned to normal, and related symptoms disappeared and were relatively stable during the follow-up period of two years. CONCLUSIONS: This is the first case of left para-aortic PGL coexisting with an ipsilateral aldosterone-producing adenoma presenting as a left para-aortic tumor associated with bilateral adrenal tumors. Awareness of the rarity of this coexistence can avoid unexpected disasters during the process of evaluation and management.

Commentary on Adrenal wash-out CT: moderate diagnostic value in distinguishing benign from malignant masses.

The increasing use of cross-sectional imaging, mainly CT, results in an accelerating number of incidental findings, for instance of adrenal tumours. Although most 'adrenal incidentalomas' are benign, it is important to identify the malignant and the hormone producing (functional) tumours. For a small fraction of adrenal incidentalomas, the diagnosis is apparent on imaging, but the large majority requires radiological characterisation. To this end, a previous joint European Society of Endocrinology and European Network for the Study of Adrenal Tumours publication in this jounal, recommends CT measurements of the native (non-contrast) tumour attenuation ≤10 Hounsfield units, consistent with a lipid-rich benign adrenocortical adenoma, and imaging at least 6 months apart, on which unchanged tumour size implies a benign tumour. Because of weak evidence, calculation of CT contrast medium washout was not recommended as a means for tumour characterisation, but this technique has nevertheless still been applied in several countries. The recent article by Schloetelburg et al. in this journal is important because, in the largest study to date, the authors confirm that calculation of CT contrast medium washout with established thresholds is insufficient to reliably characterise adrenal tumours. Their results are therefore expected to impact the management of these patients.

Pediatric adrenocortical adenoma presenting with Cushing's syndrome / Cushing-szindrómát okozó gyermekkori mellékvesekéreg-adenoma

Összefoglaló. A gyermekkorban kialakuló Cushing-szindróma ritka betegség, a leggyakrabban exogén szteroidadás következményeként jelentkezik. A daganatos betegségek közül a hypophysis kortikotropint szekretáló adenomája, illetve a mellékvesekéreg-tumorok okoznak a leggyakrabban Cushing-szindrómát. Jelen tanulmányunkban egy Cushing-szindrómával diagnosztizált fiú esetét mutatjuk be. Az endokrinológiai kivizsgálás adrenokortikotropin (ACTH)-independens hypercortisolismust támasztott alá. A hasi MRI-felvételen egy éles határral rendelkezo, 3,5 cm nagyságú terime ábrázolódott a jobb mellékvese-régióban. A tumort parciális mellékvese-eltávolítás során távolították el. A szövettani elemzés mellékvesekéreg-adenomát igazolt. A gyermek klinikailag és laborértékei alapján gyógyultnak tekintheto. A Cushing-szindrómával kezelt betegek hosszú távú nyomon követése szükséges, melynek során szükség szerint biztosítani kell a glükokortikoidok és az egyéb szteroidhormonok megfelelo pótlását, a kialakult szövodmények kezelését, és adott esetben idoben fel kell ismerni a Cushing-szindróma késoi relapsusát is. Orv Hetil. 2022; 163(10): 407-412. Summary. Cushing's syndrome (CS) in children is a rare disease, most frequently caused by either an adrenal tumor or a corticotropin-secreting pituitary adenoma. Its early detection and effective treatment are highly important to avoid the short- and long-term consequences of hypercortisolism. We report a case of a child with Cushing's syndrome resulting from an adrenocortical adenoma. Endocrinological data revealed adrenocorticotropin (ACTH) independent hypercortisolism. MRI scan of the adrenal glands showed a single, well-encapsulated tumor on the right adrenal gland with a diameter of 3.5 cm. Adrenal gland sparing surgery was performed with total excision of the tumor. The histological analysis confirmed the diagnosis of adrenal adenoma. The child was cured clinically and biochemically. The long-term follow-up of patients treated for Cushing's syndrome should include the adequate replacement of glucocorticoids and other steroid hormones, treatment of osteoporosis and other pathologic effects of hypercortisolism and long-term screening for the relapse of Cushing's syndrome. Orv Hetil. 2022; 163(10): 407-412.

Adrenocortical adenoma manifesting as Cushing's syndrome and pseudo-precocious puberty in a toddler.

Cushing's syndrome is a rare disease in the paediatric age group. Adrenocortical carcinomas (ACC) constitute the most common cause of Cushing's syndrome between 1 and 5 years of age. Often, adrenocortical carcinomas co-secrete other hormones such as androgens (testosterone), deoxy-corticosterone (DOCA), or 17-hydroxy-progesterone [17(OH)P] in addition to cortisol. This may manifest with symptoms and signs of precocious puberty along with Cushing's syndrome. It is rare for a benign adrenocortical adenoma to co-secrete androgens and other hormones in addition to cortisol. Differentiation between adenoma and carcinoma is difficult in all aspects: clinical, radiological, and histopathological. Here, we describe the case of a 2.5-year-old male child who presented with Cushing's syndrome and virilization. Although we suspected ACC clinically, the radiological and histopathological findings were suggestive of benign adrenocortical adenoma. Our case represents the diagnostic challenge that exists in paediatric adrenocortical tumours.

Gonadotrophin-independent Precocious Puberty Secondary to an Estrogen Secreting Adrenal Tumor.

BACKGROUND: Adrenal masses are rare in children and most commonly present with clinical features of virilization in the absence of activation of the pituitary axis-gonadotrophin-independent precocious puberty. OBSERVATIONS: We report an unusual case of a 7-year-old girl who presented with clinical signs suggestive of exposure to both androgens and estrogens. Imaging revealed a left-sided adrenal mass with no evidence of metastasis. She underwent successful laparoscopic unilateral adrenalectomy. Histology confirmed an adrenal adenoma. CONCLUSION: We conclude that adrenocortical tumors should be considered in children presenting with gonadotrophin-independent precocious puberty and raised estrogens.

Primary Angiosarcoma of the Adrenal Gland: Report of 2 Cases and Review of the Literature.

Primary adrenal angiosarcoma is a rare, malignant, vascular neoplasm. These neoplasms typically arise in middle age (median age of 60 years) and are more common in males (65%) than in females. Although rare, these neoplasms are aggressive with a propensity for local recurrence and metastasis and a median survival of 18 months. We present 2 cases of primary adrenal angiosarcoma with synchronous, ipsilateral adrenocortical adenomas. We review the cases of adrenal angiosarcoma reported since 1988 and discuss their clinical and histopathologic characteristics.
