Stomach, adenocarcinoma
GC.6094
Wet specimen.
Pylorus and pyloric antrum, with a small portion of the stomach and duodenum, in vertical section, showing an adenocarcinoma.
Excised from a female aged 60 years who during some months had gastric discomfort, frequent vomiting, and increasing constipation. On palpation a tumour in the pyloric region could be moved freely up and down. Neither adhesion of the stomach to the surrounding parts nor lymph vascular affection, was found on coeliotomy. The pylorus was narrowed by a tumour bulging from its posterior wall. She survived the operation twenty-six days and died of suppurative parotitis. On post mortem examination the gastroduodenal junction was found intact.
On the serous surface a smooth bulge indicates the pyloric antrum and on section this is seen to correspond with a rounded somewhat nodular tumour involving about half of the pyloric circumference. Distally the tumour is warty and irregular where it projects into the duodenum, proximally it passes somewhat gradually into the stomach wall, the mucosa of which is somewhat nodular beyond the margin of the tumour.
