Endoskopische Resektion eines seltenen Magenadenoms (Pyloric-gland-Adenom) mit Übergang in ein gut differenziertes Adenokarzinom

Abstract

We present the case of a 76-year-old lady in whom the work-up for iron-deficiency anaemia resulted in the finding of a giant gastric polyp. The polyp could be completely removed endoscopically. The final histology showed the rare entity of a pyloric gland adenoma with focal transition into a well-differentiated adenocarcinoma. The patient is well after a follow-up of 12 months. Pyloric gland adenoma was first described in 1990. In spite of its benign histological appearance, a transition into adenocarcinoma has been reported in up to 30 % of the cases. Thus, although relatively rare, the gastroenterologist/endoscopist, as well as the pathologist should be aware of the entity of pyloric gland adenoma.
