title: Adenosquamous carcinoma of the pancreas.
abstract: BACKGROUND
  Adenosquamous carcinoma of the pancreas most probably represents squamous metaplasia of an adenocarcinoma. Metastases are typically an admixture of both elements, but more frequently, adenocarcinoma.
  
  
  METHODS
  A review of 102 pancreaticoduodenectomies for masses of the head of the pancreas done between 1994 and 1998 revealed two patients with adenosquamous carcinoma of the pancreas.
  
  
  RESULTS
  Both patients underwent successful pancreaticoduodenctomy, but were found to have nodal metastasis. One patient lived 13 mo and the other lived 14 mo with both dying from metastatic disease.
  
  
  CONCLUSIONS
  Adenosquamous carcinoma of the pancreas is a rare tumor, and because its presentation, clinical features, and course are identical to adenocarcinoma of the pancreas, it should be considered in the differential diagnosis for any mass of the head of the pancreas. Survival is poor for these patients. In this series, it was 13 and 14 mo, respectively.
