Case of the Week

A needle biopsy of this pancreatic solid pseudopapillary neoplasm was labeled "gastric mass". We initially tried to make it into a neuroendocrine tumor.... Sometimes the needle is not where it is believed to be. LEF1 is a nice clean nuclear stain and easier to interpret than beta catenin.



Case by Dr. Elizabeth Montgomery, Clinical Professor, Vice Chair of Faculty Development & Mentoring, Director of Surgical Pathology Fellowship Training Program, Co-Director, Pathology Reference Services, and Editor-In-Chief at Innovative Science Press.
