**Core Concept**
Type 2 autoimmune pancreatitis (AIP) is a form of chronic pancreatitis characterized by an autoimmune inflammatory response, often associated with IgG4-related disease. The histological features of type 2 AIP are distinct from those of type 1 AIP and other pancreatic pathologies.

**Why the Correct Answer is Right**
Type 2 AIP is characterized by a diffuse or segmental infiltration of IgG4-positive plasma cells, often accompanied by lymphoplasmacytic infiltration and fibrosis. The presence of storiform fibrosis, a distinctive pattern of collagen deposition, is a hallmark of type 2 AIP. This fibrosis is often accompanied by the presence of IgG4-positive plasma cells, which can be identified using immunohistochemical staining.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because type 2 AIP is not typically characterized by a dominant acute inflammatory cell infiltrate, which is more commonly seen in acute pancreatitis or other forms of pancreatitis.
* **Option B:** This option is incorrect because type 2 AIP is not typically associated with a significant number of eosinophils, which are often seen in allergic or parasitic reactions.
* **Option C:** This option is incorrect because type 2 AIP is not typically characterized by a significant number of neutrophils, which are often seen in acute bacterial infections or other forms of pancreatitis.

**Clinical Pearl / High-Yield Fact**
When evaluating a patient with suspected pancreatic pathology, it is essential to consider the possibility of type 2 AIP, particularly in the context of a patient with a history of autoimmune disease or elevated IgG4 levels. Storiform fibrosis and IgG4-positive plasma cells are key histological features that can help distinguish type 2 AIP from other forms of pancreatitis.

**Correct Answer:** D.
