BCL10 as a useful marker for pancreatic acinar cell carcinoma, especially using endoscopic ultrasound cytology specimens

Acinar cell carcinomas ( ACCs ) of the pancreas are characterized by the histological and immunohistochemical features of acinar cell differentiation. Recently, BCL 10, originally identified as a recurrent t(1;14)(p22;q32) translocation in MALT B ‐cell lymphoma, was found to be immunohistochemically positive in some solid tumors, including ACC . To evaluate its diagnostic efficacy, we performed BCL 10 immunohistochemistry and evaluated molecular...
