  • Alpha-cell hyperplasia (ACH) is a rare pancreatic condition with various forms and is often associated with pancreatic neuroendocrine tumors (pNETs), although its causes are not well understood.
  • A 72-year-old male with type 2 diabetes was found to have a non-functioning pNET during treatment for gallbladder issues, which revealed mild glucagon elevation and led to surgery.
  • Pathological analysis showed the pNET was glucagon-producing and occurred alongside ACH, emphasizing the need for specialized testing to diagnose such cases even when symptoms suggest a non-functioning tumor.

Objectives: Therapeutic options for pancreatic neuroendocrine neoplasia (Pan-NEN) have increased over the last decade. We aim to understand the evolution of the prognosis of patients with diagnosis of Pan-NEN within a 12-year period, considering the implementation of new treatments.

Methods: This study is a retrospective cohort study of patients diagnosed with Pan-NENs between 2006 and 2017.

Background: Due to the low incidence and heterogeneous behavior of medullary thyroid carcinoma (MTC), its prognostic factors are still not well stablished. While several large studies have investigated the impact of gender in differentiated thyroid cancer (DTC), its role in MTC outcomes remains controversial. We aim to identify MTC prognostic features, specially focusing on the role of gender.

Introduction: Current guidelines specify controversial areas in adrenocortical carcinomas (ACC), such as optimal follow-up time after remission and identification of prognostic markers. We aim to address these topics by analyzing four reference centers in our country.

Methods: Cross-sectional multicentric study of 69 patients (mean age: 51.
