Pancreatic hepatocellular tumor
Pancreatology, 2005Hepatocellular differentiation of pancreatic cells has been observed under certain conditions in several species, including humans. Their cell of origin and biology has remained controversial. Generally, these lesions have been considered a degenerative process.

Cystic pancreatic lesions are common and often incidentally detected on cross-sectional examinations of the abdomen. Most lesions are asymptomatic and benign. However, some carry a significant risk of malignant degeneration, so correct identification, complete characterization, and adequate follow-up/management of these lesions are paramount.

Pancreatic Tumor Microenvironment
2020The pancreatic ductal adenocarcinoma (PDAC) microenvironment is a diverse and complex milieu of immune, stromal, and tumor cells and is characterized by a dense stroma, which mediates the interaction between the tumor and the immune system within the tumor microenvironment (TME).

Pancreatic neuroendocrine tumors
Indian Journal of Gastroenterology, 2012Pancreatic neuroendocrine tumors (pancreatic NETs) are rare, low- to intermediate-grade neoplasms thought to arise from the pancreatic islets. Recent advances in pathology and our understanding of the biological behavior of this group of tumors has resulted in changes in their nomenclature and how we treat them.

Incidental, nonfunctional pancreatic endocrine tumors (PET) are observed with increasing frequency. Most are insulinomas. Endoscopic ultrasound with fine-needle aspiration plays a significant role in the localization and tissue diagnosis of PET. Establishing PET behavior as aggressive or indolent remains challenging especially preoperatively.

In 1902, Nicholls described a tumor originating from a pancreatic islet cell lineage [1]. This was the first report of a pancreatic endocrine tumor (PET). These uncommon tumors occur in approximately 1 out of 100,000 people [2–4]. The incidence in autopsy studies is as high as 1.5% [5].

Abdominal Radiology, 2017
In this review, we will focus on rare pancreatic tumors. Most of these tumors do not have distinct characteristic appearances so the key to diagnosis requires a combination of imaging appearance, laboratory data, patient demographics, and associated medical syndromes in order to narrow the differential diagnosis. Nonetheless, imaging plays a vital role

The goal of this article is to describe the different types of benign pancreatic neoplasms, methods to distinguish between them, and treatment options. Pancreatic adenocarcinoma is associated with specific neoplastic lesions that are similar in radiographic appearance to some benign lesions.

Current Opinion in Oncology, 2001
Pancreatic endocrine tumors are rare but have long held a fascination for clinicians because of the physiologic derangements that they can cause, and the dramatic corrections that can be achieved by appropriate management. In the year reviewed in this article, the literature again demonstrated the ongoing interest and research in this area.
