title: Multiple primary malignant tumors: a rare combination in the stomach.
abstract: We have reported one case of a rare combination of multiple primary malignancies in the stomach, a leiomyosarcoma and an adenocarcinoma in a 72-year-old male. He also had a leiomyoma of the stomach and a cavernous hemangioma of the spleen. Since he has had two malignant and two benign tumors, it would appear that this patient has a tendency to develop neoplasia.
