Abstract:
Objective To estimate the incidence,clinicopathological characteristics and therapeutic features in children with solid pseudopapillary tumors of the pancreas(SPTP).Methods Nine eases of children SPTP after diagnosis were collected in our hospital.Routine HE,PAS staining and immunohiatochemical staining of multiple indicators were analyzed,combined with literature analysis of clinical manifestations,imaging,pathological features,surgical treatment and follow-up case.Results The average age in nine cases of SPTP was 10.3 years.The SPTP patients in children in our hospital accounted for 29.0% of pancreas solid tumors.Many clinical manifestations were abdominal pain(5 cases,55.56%),abdominal mass(3 cases,33.33%),jaundice(1 cases,11.11%),and other symptoms.B-ultrasonography and CT showed pancreatic lesions,clear boundary,was solid and cystic,and some have a little calcification.Pathological features:tumor limitations,capsule integrity,and cross-section alternating solid and cystic lesions,tumors organizations sheet hemorrhage,necrosis and cystic change.Immunohistochemically,the positive rates were 100% for α1-AT,66.7% for NSE,33.3% for S-100 and 100% for PAS.The patients were followed-up for 4 months to 10 years and were alive postoperatively,but no local recurrence and distant metastasis.Histological examination showed solid with cystic areas and papillary protrusions.Conclusion SPTP should be the second most common pancreatic tumor in children.Girls were more frequently affected.The overall prognosis following surgical resection was good.
