Mucinous cystic neoplasm of the pancreas (MCNP) are variable types of tumors, which predominantly affect women (90-95 %), and usually appear incidentally in the 5th to 7th decade of life. They are generally solitary lesions, with no involvement of the main pancreatic duct, rarely symptomatic and are associated with malignancy (10 % to 40 %). The aim of this manuscript was to report a case of giant mucinous cystic neoplasm of the pancreas surgically treated and review the existing evidence regarding its morphological, therapeutic and prognosis characteristics. Patient: A 29-year-old woman with a slightly symptomatic abdominal mass. The diagnosis was verified with ultrasound, computed axial tomography and magnetic nuclear resonance. The patient underwent surgery; an uneventful corporocaudal pancreatectomy with splenic preservation was performed. She was discharged on the fifth day, and has evolved adequately, without postoperative complications. MCNP is a complex lesion, which can be associated with malignancy, but the preoperative diagnosis of malignancy cannot be established with certainty. Its prognosis depends on early diagnosis and timely treatment.
