[Cystadenoma and cystadenocarcinoma of the pancreas]

The authors analyze a group of six patients with cysadenocarcinoma of the pancreas. They draw attention to the fact that 1. tumours of the type of pancreatic cystadenomas turn in recent years more frequently malignant, 2. it is important to consider whether the cystic formation of the pancreas, i.e. also an apparent pseudocyst, has a tumourous character and to supplement the examination also by a microscopic examination, and 3. if the histologist confirms a benign tumour, even then we cannot rely that the tumour does not also contain malignant foci and we cannot be certain that a cystic pancreatic tumour will permanently retain its benign character.
