Primary adrenal lymphoma (PAL) is a rare entity that presents as unilateral or bilateral rapidly growing adrenal masses, with signs and symptoms most commonly related to adrenal insufficiency due to the mass effect on the surrounding tissues. Although steroeidogenesis has not been previously described in PAL, we herein report two cases of PAL presenting as adrenal incidentalomas (AIs) that demonstrated autonomous cortisol production. A 52-year-old woman presented with lumbar pain; a computed tomography (CT) scan demonstrated a left AI measuring 8.5 × 15 × 10 cm. Similarly, an 80-year-old woman presented with lumbar pain, demonstrating in a CT scan a bilateral AI (right: 9 × 6.5 cm, left: 3.6 × 3.2 cm). Both cases underwent a full hormonal evaluation according to the algorithm for the investigation of AIs, demonstrating increased 24-h cortisol excretion, suppressed fasting adrenocorticotropic hormone (ACTH) levels, and non-suppressed serum cortisol levels in both the overnight and the low-dose dexamethasone suppression tests, indicating autonomous cortisol secretion and Cushing's syndrome. In a relatively short time, both patients developed night sweats, and their clinical picture deteriorated, while the CT scans showed increased dimensions of the masses with radiological characteristics compatible to lymphoma. Both patients underwent ultrasound-guided biopsies (FNBs), revealing infiltration of the left adrenal by diffuse large B-cell lymphoma in the first case, whereas bilateral adrenal infiltration from the same histological type was noted in the second case. Subsequently, they were treated with immunochemotherapy, but the second patient died from an infection shortly after the initiation of the treatment. To our knowledge, this is the first report of PAL presenting with Cushing's syndrome due to autonomous cortisol production, indicating that neoplastic lymphoid cells in PAL might acquire the potential for steroidogenesis; therefore, more cases of PAL should be analyzed so as to further elucidate the complex pathogenesis and the natural course of this entity.

Introduction: Obesity in childhood and adolescence is associated with complications that resemble those seen in hypercortisolism. Hair cortisol concentration (HCC) in children is a reliable marker of long-term endogenous cortisol concentrations. We determined HCC in overweight and obese children and adolescents, and examined the relation between HCC and other cardiometabolic parameters., Methods: Three hundred children and adolescents aged 4-18 years (mean age ± standard error of the mean [SEM]: 10.49 ± 0.15 years; 140 [46.7%] obese, 94 [31.3%] overweight, 66 [22%] of normal BMI; 76 males, 224 females) were studied prospectively. Blood samples for determination of hematological, biochemical, and endocrinologic parameters were obtained. Systolic (SBP) and diastolic blood pressure (DBP) was determined. Scalp hair samples were collected from the posterior vertex, and HCC was measured using an electrochemiluminescence immunoassay., Results: Obese subjects had significantly higher SBP, DBP, waist and hip circumferences, waist-to-hip ratio, waist-to-height ratio, ALT, γ-GT, triglycerides, apolipoprotein-B, insulin, and HbA1C concentrations than overweight and normal-BMI subjects. HCC did not differ significantly among the three groups of subjects (mean ± SEM: 8.74 ± 0.43 vs. 8.88 ± 0.52 vs. 9.33 ± 0.72, all p > 0.05). No significant association was noted between HCC and cardiometabolic or body composition parameters. HCC was significantly higher in prepubertal girls than prepubertal boys (9.45 ± 0.38 vs. 7.35 ± 0.39, p = 0.007)., Conclusion: In our study, overweight and obesity was not associated with elevated HCC. Furthermore, no association was found between HCC with cardiometabolic parameters and fat mass. Further studies are required to delineate the association between overweight/obesity and HCC., (© 2019 S. Karger AG, Basel.)

The use of opioids has grown substantially over the past two decades reaching the dimensions of a global epidemic. These drugs have effects on multiple levels of the endocrine system through mechanisms which are still not fully elucidated, and awareness of their endocrine sequelae is vital for all specialists prescribing or managing patients on them. Hypogonadism is the most well-recognised consequence of opioid use (prevalence 21–86%) which, however, may remain undiagnosed with potential adverse outcomes for the patients. Although less frequent, cortisol deficiency can also be found. Furthermore, there is a negative impact on bone health (with reduced bone mineral density and increased fracture risk) and occasionally hyperprolactinaemia, whereas the clinical significance of alterations in other hormones remains to be clarified. Discontinuation or reduction of the opioid and, in cases of chronic pain, consideration of alternative therapies for pain relief are potential management options. Hormonal replacement, especially when the above measures are not practically feasible, needs to be considered. Further studies are needed to clearly establish the prevalence of hormonal abnormalities with various regimes, doses and routes of opioids and to address reliably the long-term benefits and risks of hormonal treatment in patients on opioids. Until evidence-based, safe and cost-effective clinical guidelines become available, periodical assessment of the gonadal and adrenal function (particularly when relevant clinical manifestations are present) and evaluation of the bone health status are advised., (© 2018 European Society of Endocrinology)
