%X A pancreatic collision tumor is a rare entity that can be challenging to diagnose. We present a very rare case of a pancreatic collision tumor composed of both a neuroendocrine tumor and a ductal adenocarcinoma. Preoperative diagnosis was clinically challenging because both the radiology and fine-needle biopsy were consistent with a typical neuroendocrine mass. However, gross examination of the mass postoperatively revealed neuroendocrine cells with rare foci of ductal adenocarcinoma without a transition zone. Awareness of this entity is important so that medical practitioners consider pursuing surgical management of pancreatic lesions that otherwise would be managed exclusively with surveillance
