title: [So-called lymphoepithelioma of the lymphoid pharyngeal ring].
abstract: A retrospective analysis of 43 observations of "lymphoepitheliomas" has shown that in 34 cases this diagnosis was referred to low-differentiated cancer with lymphocytic infiltration, and in 9 cases--to reticulosarcomas (an epitheliod variant). The authors suggest some signs as an adjunct for the differential diagnosis between an epithelioid variant of reticulosarcoma and low-differentiated cancer. It is necessary to exclude lymphocytic epithelioma as an onconosollogical unit, since it does not exist as a double-tissue tumor.
