Poorly Differentiated Gastric Adenocarcinoma (high magnification)
The tumor is composed of irregular tubules, single cells, and solid areas of cells. The single cells show large, hyperchromatic nuclei, prominent nucleoli and scant cytoplasm. The intervening stroma contains inflammatory cells. The presence of some tubular structures makes this a poorly differentiated adenocarcinoma. The tubular structures are not as well developed as they would be in a well differentiated adenocarcinoma, but are nevertheless present. Undifferentiated carcinomas do not have glandular structures. Undifferentiated carcinomas require immunohistochemistry to help in making the diagnosis.
