Malignant pancreatic tumor other than solid pseudopapillary tumor in pediatric patients: A single-center experience.

ABSTRACT

ABSTRACT Pancreatic tumors, except solid pseudopapillary tumors (SPTs), are rare in pediatric patients. Herein, we report various types of pancreatic tumors in pediatric patients and review the literature regarding their treatments and prognosis.We retrospectively reviewed the data of pediatric patients who underwent surgery for pancreatic tumors, excluding SPTs, between January 2009 and December 2019 at Seoul National University Children's Hospital. A total of 35 pediatric patients were identified as having undergone surgery for pancreatic tumors. Of these patients, 30 were excluded because the tumor was identified as an SPT.The diagnoses of the five remaining (non-SPT) pancreatic tumors were pancreatic neuroendocrine tumor, mixed acinar neuroendocrine carcinoma, kaposiform hemangioendothelioma, and intraductal papillary mucinous neoplasm. All five patients survived; however, recurrence and liver metastasis were observed in one patient. The detailed demographics, treatments, and prognosis of each patient were reviewed.Despite the rarity and low incidence of pancreatic tumors in pediatric patients, four types of non-SPT tumors are reported here. Hence, the possibility of these should not be overlooked, especially since the diagnosis and adjuvant treatment differ vastly between the tumor types.
