Notes
**Note 1:** **Islets of Langerhans** * Islets of Langerhans are distributed throughout the pancreas; an islet tumor is coded according to the subsite of the pancreas in which the tumor arises if the information is available. **Note 2:** **Abutment, encasement** * The terms "abutment," "abut(s)," "encases," or "encasement" of the major blood vessels can be interpreted as involvement of these structures.Default
