[Papillary cystic neoplasms in the ectopic pancreas].

The authors reported a case of a young woman. From her omentum a clinically and radiologically benign tumour was removed that had been observed for years and caused minor symptoms. Histologically the tumour proved to be a so called papillary and cystic tumour that originated from ectopic pancreatic tissue. The histological diagnosis was justified by immunohistochemical and electronmicroscopical examinations. Reports of this type of tumour evolving in an ectopic pancreas appeared only twice in the world literature to the knowledge of the authors.
