Neuroendocrine carcinoma (NEC) of the pancreas is rare. We report the case of a 34-year-old man with pancreatic NEC with soft tissue metastasis. The patient presented with right upper abdominal discomfort. Computed tomography revealed a low-density heterogeneous mass in the tail and body of the pancreas that encroached on the greater curvature of the stomach and spleen. We performed exploratory laparotomy and total pancreatectomy with splenectomy and total gastrectomy. Histopathological analysis showed spindle-shaped cells with scanty cytoplasm and hyperchromatic nuclei, confirming a primary pancreatic NEC. One month after the surgery, the patient experienced leg swelling. Positron emission tomography-computed tomography revealed high uptake of fludeoxyglucose in the left leg, and the leg was amputated. Histopathological analysis confirmed metastasis of pancreatic NEC. The patient was followed up and received chemotherapy (etoposide and cisplatin). One month after amputation, the level of tumor marker neuron-specific enolase was 142.70 μg/L and computed tomography scan revealed an aggravated metastatic lesion. The patient suffered from unbearable pain and we treated him with odynolysis. Four months postoperatively, the patient died of respiratory failure.

Delta-like protein (DLL3) is a novel therapeutic target. DLL3 expression in gastroenteropancreatic neuroendocrine tumors (GEP-NECs) is poorly understood, complicating the distinction between well-differentiated neuroendocrine tumors G3 (NET G3) and poorly differentiated NEC. DLL3 immunohistochemistry (IHC) was performed on 248 primary GEP-NECs, correlating with clinicopathological parameters, NE markers, PD-L1, Ki67 index, and prognosis.

Background: Gallbladder neuroendocrine carcinoma (NEC) represents a subtype of gallbladder malignancies characterized by a low incidence, aggressive nature, and poor prognosis. Despite its clinical severity, the genetic alterations, mechanisms, and signaling pathways underlying gallbladder NEC remain unclear.
Case Summary: This case study presents a rare instance of primary gallbladder NEC in a 73-year-old female patient, who underwent a radical cholecystectomy with hepatic hilar lymphadenectomy and resection of liver segments IV-B and V.

A 78-year-old male patient came to our hospital with a chief complaint of fever. Computed tomography revealed an indistinct tumor in the pancreatic head, along with dilatation of the bile duct and main pancreatic duct. An endoscopic transpapillary biopsy demonstrated adenocarcinoma in the glandular epithelium and a dense formation of quasi-round cells.

Herein, we characterized the percentage of tacrolimus to the combined sirolimus and tacrolimus trough levels (tacrolimus %) observed during islet transplant-associated immune suppression therapy with post-transplant skin cancer. Although trough levels of tacrolimus and sirolimus were not different ( = 0.79, 0.

Background/objective: Patient-derived organoids (PDOs) have emerged as essential for ex vivo modelling for pancreatic cancer (PDAC) but reports on efficacy and organoid take rate are scarce. This study aimed to assess the feasibility of establishing PDOs from resected specimens in periampullary tumors.
Methods: Patients undergoing surgery for suspected periampullary cancer were included.
