Endoscopic ultrasound-guided histological diagnosis of a mucinous non-neoplastic pancreatic cyst using a specially designed through-the-needle microforceps

This case clearly illustrates the diagnostic challenge of pancreatic cysts. The novel through-the-needle microforceps allowed the acquisition of tissue that showed all of the histological criteria needed for a diagnosis of mucinous non-neoplastic cyst. These results allowed us to choose the most appropriate management for this patient, which, importantly, would have been different if based on CEA results alone. Mucinous non-neoplastic cysts are, in fact, benign conditions, without any malignant potential and for which both surgery and surveillance are not necessary.
