Plexiform angiomyxoid myofibroblastic tumour of the duodenum: a rare entity

Abstract

Plexiform angiomyxoid myofibroblastic tumour (PAMT) has recently emerged as a new entity among gastrointestinal mesenchymal tumours. All of the 27 cases reported until now originated from the stomach. We report the first case of a duodenal PAMT arising from the first part of the duodenum in a 19-year-old woman presenting with upper abdominal pain and an abdominal lump.
