We report a case of malignant tumor of the stomach showing both carcinoma and
sarcoma components in a 47 year-old woman. The resected stomach revealed two
tumors which were in different location. The one mass was a 2¡¿1 §¯, poorly
demarcated tumor at the body, along the lesser curvature and the other was a 6¡¿7 §¯,
well demarcated polypoid tumor with a central depression at cardia of the posterior
stomach wall. The tumor at the body was a poorly differentiated adenocarcinoma which
showed strong reactivity for CEA. The tumor at the cardia was composed of epithelioid
or spindle shaped cells with abundant eosinophilic cytoplasm and revealed 5¡6 mitoses
per ten high power field. The tumor at the cardia was diagnosed as epithelioid
leiomyosarcoma and showed reactivity for vimentin but none for actin, desmin, keratin,
and CEA. This is different from the usual carcinosarcoma.
