Aim: The aim of this study is to describe the incidence, imaging characteristics and pathological features of pancreatic incidentalomas. Moreover, surgical indications are discussed according to the nature and location of the neoplasms.
Background: Pancreatic incidental lesions are more commonly diagnosed, due to the widespread of high quality cross sectional imaging. These lesions can be cystic or solid, benign, pre-malignant or already malignant and they cover a wide spectrum of histological diagnosis. Cystic lesions are more commonly benign or at least pre-malignant. Surgery should be reserved in case of unexpected changes in aspect during follow-up or for large cysts (>3 cm). Among solid pancreatic incidentalomas, ductal adenocarcinoma is the most common diagnosis, followed by neuroendocrine tumors. Surgical treatment of pancreatic incidentaloma depends on the location of the tumor: a Whipple's procedure should be performed for neoplasms of the head, while distal pancreatectomy is indicated for body and tail lesions. Pancreatic surgery is still delicate and burdened by serious complications. Both procedures can be performed with minimally-invasive technique which is connected to lower complications rate but, at present, they have shown no advantages in terms of mortality and oncologic outcomes.
Conclusions: Pancreatic incidentalomas are becoming more and more common but when and how to operate them is still subject of debate. Precise criteria about treatment strategy are still lacking and definite guidelines are needed to clarify the best approach.
Key Words: Incidentaloma, Laparoscopy, Pancreatic tumors, Surgery.

Objective: To investigate the prevalence and incidence of dementia in patients with non-overtly functional adrenal tumours (NOFATs).
Design: A national retrospective register-based study was conducted on patients diagnosed with NOFAT and controls diagnosed between 2005 and 2019, in Sweden. Individuals diagnosed with overt adrenal hormone excess or previous malignancies were excluded.

Article Synopsis
- Nonfunctional adrenal tumors (NFAT) were examined to determine if they correlate with a higher incidence of cancer through a nationwide study in Sweden involving over 17,000 NFAT cases and nearly 125,000 control individuals without adrenal tumors.
- The study found that patients with NFAT had a significantly increased risk of developing various cancers, including adrenal, thyroid, and breast cancers, with a hazard ratio of 1.35 compared to controls.
- The findings suggest that patients with NFAT may require long-term health monitoring for potential cancer development, although some other health conditions showed no significant association after adjustments.

Introduction: Pancreatic lesions have varied morphology and presentation making their diagnosis challenging. The lesions may be asymptomatic incidentalomas on abdominal imaging for other conditions, symptomatic producing specific hormone effects or causing local effects.
Case: We report a 35-year-old woman with recurrent abdominal pain confirmed gastroesophageal reflux disease.

Context: Adrenal incidentalomas, including nonfunctioning adrenal incidentalomas (NFAI), are associated with a high prevalence of diabetes mellitus (DM). While NFAI is diagnosed by exclusion when no hormone excess exists, subtle cortisol secretion may exist and contribute to DM development. However, it alone cannot explain the increased risk, and whether other steroid metabolites are involved remains unclear.

Neuroendocrine neoplasms (NENs), also known as neuroendocrine tumors (NETs), are rare tumors derived from cells with characteristics of both nerve and endocrine cells. The clinical presentation, diagnosis, and treatment of NENs vary significantly depending on the type, location, whether the neoplasm is hormonally functional, how aggressive it is, and whether it has metastasized to other parts of the body. This article provides an overview of specific types of NETs, clinical presentations and related syndromes, diagnosis, and approach to management of common NENs.
