Abstract
Only two cases of concomitantly occurring adenosquamous and neuroendocrine tumours (NET) have been reported in the literature. We report a case where both NET and adenosquamous are simultaneously occurring. A 42-year-old lady was hospitalized following painless jaundice and loss of weight. Computer tomography scan showed 3.0 x 2.9 cm hypo enhancing and hypovascular mass in the uncinate/head process. Another hypervascular mass was seen in the body of the pancreas. Pathological examination showed that the lesion in the uncinate process/neck of pancreas was an adenosquamous in the main pancreatic duct intraductal papillary mucinous neoplasm. The second tumour was a NET measuring 36 mm with no metastatic involvement. These findings suggested concurrently occurring but separated adenocarcinoma and NET tumours. This is the third case in the literature where both NET and adenosquamous are happening concomitantly, and the previous two other cases are also reviewed in the article.
