Title: Argentaffin cells, intestinal metaplasia and antral metaplasia in carcinoma of the gall bladder. Author: Azadeh B, Parai SK. Journal: Histopathology; 1980 Nov; 4(6):653-9. PubMed ID: 7439893. Abstract: The occurrence of argentaffin cells, intestinal metaplasia, and antral metaplasia has been studied in 20 gall bladders with carcinomas, in a papilloma, and in 20 specimens of cholelithiasis. Argentaffin cells were present in six carcinomas, but in only one specimen were they present in large numbers. Only one adenocarcinoma contained occasional argyrophil cells and no argentaffin or argyrophil cells were seen in the papilloma. Five of the 20 specimens of cholelithiasis contained occasional argentaffin cells. Intestinal and antral metaplasia were found in four carcinomas, in the papilloma, and in seven of the 20 specimens of cholelithiasis. It is suggested that metaplastic changes may play a role in the pathogenesis of carcinoma of the gall bladder.[Abstract] [Full Text] [Related] [New Search]
