Pediatric Neuroendocrine Tumors in Denmark: Incidence, Management, and Outcome From 1995 to 2020.

Background: Neuroendocrine tumors (NETs), although rare, are considered one of the most common gastrointestinal and bronchopulmonary pediatric neoplasms. We aimed to determine the incidence, tumor characteristics, management, and outcome of NETs and explore the role of genetic predisposition, focusing on low and intermediate grade tumors.

Methods: Using the Danish National Pathology Registry, we conducted a nationwide retrospective study including all Danish children aged ≤18 years diagnosed with a pathology-proven NET between 1995 and 2020.

Gemcitabine-induced extensive skin necrosis.

An 82-year-old woman presented with oedema and extensive necrotic ulcerative lesions on the back side of her lower limbs, emerging after the second cycle of chemotherapy consisting of Gemcitabine for metastatic pancreatic cancer. The absence of any convincing argument in favor of cardiovascular or autoimmune disease led us to attribute the onset of skin necrosis to chemotherapy administration. Although skin ischemia has also been described as a paraneoplastic syndrome, in this case we could observe a temporal and causal relationship to Gemcitabine infusion.
