We aim to demonstrate that a surface-enhanced Raman spectroscopy (SERS) probe can be effectively used for protein detection in adrenal tumors. The SERS probe method, which uses Au@Ag core-shell nanoparticles conjugated with a CgA antibody and a SERS reporter, was applied to detect CgA in adrenal tumors. Our data reveal that the results of the CgA-SERS probe method were almost identical to those of western blot and superior to those of traditional immunohistochemistry. This study offers a novel strategy to detect CgA in adrenal tumors and provides more reliable protein test results than traditional immunohistochemistry analysis for adrenal pathologists, meaning that it might be a better clinical reference for the diagnosis of pheochromocytoma.

Elevated cortisol in chronic stress and mood disorders causes morbidity including metabolic and cardiovascular diseases. There is therefore interest in developing drugs that lower cortisol by targeting its endocrine pathway, the hypothalamic-pituitary-adrenal (HPA) axis. However, several promising HPA-modulating drugs have failed to reduce long-term cortisol in mood disorders, despite effectiveness in other hypercortisolism conditions such as Cushing's syndrome.

Purpose: Adrenocortical carcinoma (ACC) is a rare, aggressive pediatric malignancy. Advanced ACC requires multimodal treatment, including surgery and systemic chemotherapy including cisplatin, etoposide, doxorubicin, and mitotane. This is associated with significant gastrointestinal toxicity, resulting in many patients being unable to complete scheduled therapy.

We introduce a 39-year-old man with an exceedingly large adrenal schwannoma who visited our outpatient department with epigastric pain and a palpable mass in the left upper abdomen. Abdominal computed tomography revealed a giant cystic lesion measuring >25 cm. Laparotomy was performed for tumor excision and partial nephrectomy.

Introduction: Advances in imaging methods have led to an increasingly frequent diagnosis of adrenal gland lesions as incidental findings. Despite progress in this field, there is still limited information regarding the epidemiology of the clinical and metabolic profile of patients with adrenal incidentaloma (AI). The objective is analyze the epidemiology of adrenal tumors at Gaffrée e Guinle University Hospital (HUGG) and compare it with data from the literature.
