title: [MALT gastric lymphoma--principles of morphological diagnosis].
abstract: MALT gastric lymphoma presents difficulties for morphological diagnosis as it is represented by neoplastic elements having morphology of mature cells. 75 MALT-lymphomas of the stomach with polymorphous tumour infiltrate are reported. The infiltrate was analyzed by cell composition, cell atypia, the presence of lymphoepithelial lesions (LEL) and lymphoid follicles, blast cells and "blast" LEL. Immunohistochemistry may be necessary for diagnosis when clear-cut morphological characteristics are lacking.
