Core Tip

Core tip: We present a rare case of adenosquamous pancreatic carcinoma (ASPC) arising in an intraductal papillar mucinous neoplasm in a CDKN2A germline mutation carrier from a kindred with familial atypical multiple mole melanoma. The case is an accelerated model of the adenoma-carcinoma sequence in pancreatic carcinogenesis. We discuss the differential diagnoses of squamous lesions in the pancreas and review the clinical and morphological features of ASPC.
