Figure 1 Comparison of endoscopic ultrasound-guided fine needle aspiration with International Consensus Diagnostic Criteria.
EUS-FNA: Endoscopic ultra-sound-guided fine needle aspiration; LPSP: Lymphoplasmacytic sclerosing pancreatitis; IDCP: Idiopathic duct-centric pancreatitis; OOI: Other organ involvement; AIP: Autoimmune pancreatitis; NOS: Not otherwise specified.
Figure 2 Endoscopic ultrasound-guided fine needle aspiration specimen of "definitive type 1 autoimmune pancreatitis”.
A, B: Hematoxylin and eosin staining of a resected pancreas specimen obtained by endoscopic ultra-sound-guided fine needle aspiration shows replacement of the acinar structure by lymphoplasmacytic infiltration and fibrosis; C: Numerous plasma cells show positive immunoreactivity for immunoglobulin G4.
Figure 3 Endoscopic ultrasound-guided fine needle aspiration specimen of "probable type 2 autoimmune pancreatitis”.
A, B: Hematoxylin and eosin staining of a resected pancreas specimen obtained by endoscopic ultra-sound-guided fine needle aspiration shows the infiltration of neutrophils in addition to lymphocyte infiltration and fibrosis; C: Immunostaining for immunoglobulin G4 is negative.
