Abstract Estrogen-secreting adrenocortical carcinoma (ACC) is exceedingly rare, representing 1% to 2% of all ACCs. We present a case of a 65-year-old man diagnosed with an estrogen-secreting, 4.3-cm right adrenal mass discovered during work-up for bilateral gynecomastia. Gynecomastia and hyperestrogenism resolved after laparoscopic adrenalectomy, and pathology was reported as adrenocortical adenoma. However, 5 years later, he again developed bilateral gynecomastia because of recurrent hyperestrogenism. Imaging revealed multiple metastases in the abdomen. Urine steroid profiling demonstrated increased androgen precursors, androgen metabolites, and glucocorticoid precursors. Ultrasound-guided biopsy of one of the metastases confirmed ACC. Initial therapy included debulking surgery with removal of metastatic lesions. Mitotane therapy was initiated 4 weeks later along with hydrocortisone for anticipated mitotane-induced adrenal insufficiency. Histopathology from the adrenalectomy specimen 5 years earlier was rereviewed and confirmed ACC. Estrogen-secreting adrenal tumors are exceedingly rare, and the majority are malignant. This case underlines the importance of making an initial accurate diagnosis of adrenal malignancy that allows better surgical planning and appropriate monitoring. Indeterminate imaging characteristics of the adrenal mass, as well as the presentation with estrogen excess, suggested an elevated risk for ACC. Initial pathology-based misdiagnosis illustrates the need for an expert adrenal pathologist to review these rare tumors.

Abstract Objective Overnight metyrapone test (OMT) is a dynamic test used to diagnose secondary adrenal insufficiency (SAI). Data on OMT use and its safety are scarce. We aimed to describe the indications and safety of outpatient OMT and compare OMT to the cosyntropin stimulation test (CST). Design Single‐centre retrospective study of adult patients undergoing OMT between 1 April 2018 and 27 January 2023. Measurements OMT‐related adverse events, post‐OMT diagnosis of SAI, and OMT comparison to CST. Results OMT was performed in 114 patients (81, 71% women) at a median age of 48 (interquartile range 37–58). The pretest probability for SAI was low in 52 (46%) patients, moderate in 48 (42%) patients and high in 14 (12%) patients. Adverse events were reported in 7 (6.1%) patients and were mild except for one hospitalization. No baseline or OMT‐related factors were associated with the development of adverse events. Prevalence of the OMT‐based SAI diagnosis was 26 (23%) and 47 (46%) using 11‐deoxycortisol cutoff <7 and <10 mcg/dL, respectively. Higher pretest probability was associated with the OMT‐based diagnosis of SAI. Post‐OMT 11‐deoxycortisol cutoff of 10 mcg/dL was used most to diagnose SAI. Compared to the OMT‐based diagnosis of SAI (11‐deoxycortisol cutoff of 10 mcg/dL), the specificity of CST was 100%, but the sensitivity was only 52%. Conclusions OMT was well tolerated and used in patients with low and moderate pretest probability for SAI. CST can erroneously exclude patients with SAI. Thus, OMT should be considered in selected patients with normal CST.

Abstract Objective Frailty, characterized by multi-system decline, increases vulnerability to adverse health outcomes and can be measured using Frailty Index (FI). We aimed to assess the prevalence of frailty in patients with adrenal disorders (based on hormonal sub-type) and examine association between FI and performance-based measures of physical function. Design Multi-centre, cross-sectional study (March 2019-August 2022). Methods Adult patients with adrenal disorders (non-functioning adrenal adenomas [NFA], mild autonomous cortisol secretion [MACS], Cushing syndrome [CS], primary aldosteronism [PA]) and referent subjects without adrenal disorders completed a questionnaire encompassing 47 health variables (comorbidities, symptoms, daily living activities). FI was calculated as the average score of all variables and frailty defined as FI ≥ 0.25. Physical function was assessed with hand grip, timed up-and-go test, chair rising test, 6-minute walk test, and gait speed. Results Compared to referent subjects (n = 89), patients with adrenal disorders (n = 520) showed increased age, sex, and body mass index-adjusted prevalence of frailty (CS [odds ratio—OR 19.2, 95% confidence interval—CI 6.7-70], MACS [OR 12.5, 95% CI 4.8-42.9], PA [OR 8.4, 95% CI 2.9-30.4], NFA [OR 4.5, 95% CI 1.7-15.9]). Prevalence of frailty was similar to referent subjects when post-dexamethasone cortisol was &lt;28 nmol/L and was higher when post-dexamethasone cortisol was 28-50 nmol/L (OR 4.6, 95% CI 1.7-16.5). FI correlated with all measures of physical function (P &lt; .001). Conclusions Whilst frailty prevalence was highest in patients with adrenocortical hormone excess, even patients with NFA demonstrated an increased prevalence compared to the referent population. Future longitudinal studies are needed to evaluate the impact of various management strategies on frailty.

Abstract Objective Prospective data on determinants of muscle strength impairment and quality of life in patients with various subtypes and severity of endogenous hypercortisolism are lacking. Design Single-center cross-sectional study, 2019 to 2022. Methods Patients with Cushing syndrome (CS) and mild autonomous cortisol secretion (MACS) were assessed with clinical and biochemical severity scores, muscle function (nondominant hand grip strength and sit-to-stand test), and quality of life (Short Form-36 [SF36] and CushingQoL). Referent subjects were recruited from the local population undergoing abdominal imaging for reasons other than suspected adrenal disorder. Results Of 164 patients, 81 (49%) had MACS, 14 (9%) had adrenal CS, 60 (37%) had pituitary CS, and 9 (5%) had ectopic CS. Median age was 53 years (interquartile range: 42-63 years), and 126 (77%) were women. The SF36 mental component score was similarly low in patients with MACS vs CS, but physical component score was lower in CS when compared to MACS (mean of 34.0 vs 40.5, P = .001). Compared to MACS, patients with CS had lower scores on the standardized CushingQoL (mean of 47.1 vs 34.2, P &lt; .001). Compared to referent subjects, patients with MACS demonstrated reduced muscle strength, similar to patients with CS (mean sit to stand Z-score of −0.47 vs −0.54, P = .822). Clinical severity (r = −0.22, P = .004) but not biochemical severity was associated with sit-to-stand test performance. Conclusions Both patients with overt CS and MACS demonstrate reduced muscle strength and low quality of life. The clinical severity score utilized is associated with both physical and psychosocial components of CushingQoL and with the physical component of SF36.
