Diagnostic and therapeutic endoscopic approaches to intraductal papillary mucinous neoplasm

Figure 2 An optical coherence tomography image of a patient with borderline intraductal papillary mucinous neoplasm (A) and photomicrograph of an intraductal papillary mucinous adenoma in the same patient (B). A: Multiple cystic lesions are pictured here with medium to high scattering in the cyst cavity; the scattering suggests the existence of mucin. A single, mucinous cystic lesion is indicated by the white arrow and scattering is clearly seen within the cystic structure.

The cysts are lined by a single layer of foveolar-type epithelial cells. Focally, papillary areas are identified.
