Benign gastrointestinal stromal tumour of oesophagus – http://id.who.int/icd/entity/1572683579

This is a common benign mesenchymal tumour that arises from cells lining the oesophagus. It is generally immunohitochemically positive for KIT (CD117), phenotypically paralleling Cajal-cell differentiation, and most examples contain KIT- or PDGFRA-activating mutations.
