Intraductal tubulopapillary neoplasm (ITPN) of the pancreas with invasive cancer misdiagnosed as a mesenteric cyst for 12 years: a case report and literature review.

Introduction: An intraductal tubulopapillary neoplasm (ITPN) depicts a distinct entity in the subgroup of premalignant epithelial tumors of the pancreas. Due to the rarity of ITPN, information regarding the disease is currently limited. We present herein a case of pancreatic ITPN with invasive cancer that was misdiagnosed as a mesenteric cyst during a 12-year follow-up period.

[A study of correlation between the blood supply types of PHcc on spiral CT and the level of VEGF expression in PHcc].

Objective: To study the correlation between the blood supply types of primary hepatocellar carcinoma (PHcc) on Spiral CT and the level of vascular endothelial growth factor (VEGF) expression in PHcc for improvement in treatment strategies and prognostication.

Methods: Forty-five cases of PHcc identified by operation and pathology were investigated. Immunohistochemistry staining in SP was performed.
