Background: Distinguishing serous cystadenoma, a benign pancreatic cyst, from potentially malignant mucinous pancreatic cystic lesions carries significant clinical and prognostic implications; and while endoscopic ultrasound-guided fine needle aspiration is the standard diagnostic tool, its low diagnostic yield often results in additional workup.

Objective: This study evaluates diagnostic yield of fine needle biopsy (FNB) on lesions suggestive of serous cystadenoma on endoscopic ultrasound.

Methods: Patients with microcystic EUS appearance were identified through retrospective chart review in two institutions.
