Fig. 2From: Two cases of resectable pancreatic cancer diagnosed by open surgical biopsy after endoscopic ultrasound fine-needle aspiration failed to yield diagnosis: case reportsPathological analysis by EUS-FNA compared to open surgical biopsy in case 1. a Macroscopic view of specimen obtained by EUS-FNA. The specimen contained large quantities of blood clots. b Microscopic view of specimen (×100 magnification) revealed enlarged nuclei and disordered ductal structures. c Specimen obtained by open surgical biopsy. Most of the specimen consisted of pancreatic parenchyma. d Microscopic view of specimen obtained by open surgical biopsy (×100 magnification) revealed abundant dyskaryotic cells with enlarged nuclei, disordered ductal structuresBack to article page
