title: Composite marginal zone B cell lymphoma and enteropathy-type T cell lymphoma of the stomach: a case report.
abstract: We describe a 64-year-old patient with gastric synchronous extranodal marginal zone B cell lymphoma of mucosa-associated lymphoid tissue and enteropathy-type T cell lymphoma. The simultaneous occurrence of mucosa-associated lymphoid tissue lymphoma and enteropathy-type T cell lymphoma is exceptional and has never been reported. We discuss the possible pathogenetic relationship between the two neoplasms.
