Mucinous cystic neoplasm of the pancreas (MCNP) is an uncommon, oligosymptomatic tumor that is typically diagnosed incidentally and predominantly affects females (90-95 %) between the 5th and 7th decades of life. These neoplasms are characterized by presenting as solitary lesions, without involvement of the main pancreatic duct. Could be associated with malignancy in 10 % to 40 % of cases. The aim of this study was to report the results of patients with MCNP who underwent surgery and to review the existing evidence regarding their morphological, therapeutic and prognostic characteristics. Seven patients (6 female), with a mildly asymptomatic abdominal mass. The diagnosis was confirmed by ultrasound, computed tomography and magnetic resonance imaging. They underwent surgery, performing a corporocaudal pancreatectomy. There were no postoperative complications or mortality. Patients were discharged after 3 days and have progressed well, with no postoperative complications, with a median follow-up of 36 months. MCNP is a lesion that may be associated with malignancy, which cannot be established with certainty in the preoperative stage. The prognosis depends on early diagnosis and timely treatment.
