Abstract:
A 45-year old man was admitted with a history of
epigastric pain for 3 months. Physical examination, routine
blood tests and abdominal ultrasound were unremarkable.
Oesophagogastroduodenoscopy (OGD) showed a
sessile mass with normal overlying mucosa arising from
the upper part of the body on the anterior wall of the
stomach close to the lesser curvature (Figure 1). Multiple
biopsies were taken and the histology showed normal
gastric mucosa. Contrast enhanced CT scan of the abdomen
showed a submucosal mass arising from the body of
the stomach suggestive of a gastro-intestinal stromal
tumour (GIST). There was no evidence of infiltration across
the stomach wall or regional lymphadenopathy.
Endoscopic ultrasound (EUS) showed a predominantly
hyperechoic submucosal lesion (Figure 2). The patient
underwent open surgery and the lesion was completely
excised. Histology showed heterotopic pancreatic tissue
in the submucosa of the stomach.
