title: Multiple primary cancers arising from different organs and tissues.
abstract: The simultaneous development of a lymphoma and an adenocarcinoma of the stomach in a patient is reported. This occurrence is exceedingly rare. Moreover, the presence of a third neoplasm in the axillary lymph nodes, manifested as secondaries from a squamous cell carcinoma, makes this case unique in the literature. The concept and postulated causes of multiple malignant tumours are discussed.
