This image shows a pancreatic islet when pancreatic tissue is stained and viewed under a microscope. Parts of the digestive ("exocrine") pancreas can be seen around the islet, more darkly. These contain hazy dark purple granules of inactive digestive enzymes .
There are about 1 million islets distributed throughout the pancreas of a healthy adult human. While islets vary in size, the average diameter is about 0.2 mm. [5]:928 Each islet is separated from the surrounding pancreatic tissue by a thin, fibrous, connective tissue capsule which is continuous with the fibrous connective tissue that is interwoven throughout the rest of the pancreas.
Islet transplantation is the transplantation of isolated islets from a donor pancreas into another person. It is a treatment for type 1 diabetes. [1] Once transplanted, the islets begin to produce insulin, actively regulating the level of glucose in the blood.

Light microscopy of acinar cell carcinoma. Relative incidences of various pancreatic neoplasms, with acinar cell carcinoma annotated near top right. [5] Light microscopy of an acinar cell carcinoma biopsy typically shows granular appearance. [6] Immunohistochemistry is usually positive for trypsin, chymotrypsin and lipase. [6]
Histopathology of IPMN types in a distal pancreatectomy specimen from a 60-year-old man, by gross pathology (center image), microscopy and immunohistochemistry: The resected specimen (c) revealed that the mural nodule in the MPD consisted of PB-type IPMN with high-grade dysplasia (adenocarcinoma) (a) with a diffuse positivity of p53 immunostaining (an insert) and KRAS mutation (G12V).
