title: [Mesoblastic nephroma].
abstract: Three cases of the "cellular" variant of mesoblastic nephroma are reported. A feature of one of them was prolonged (7.5 months) spontaneous development of the tumor which presented a peculiar morphologic appearance. Diagnostic differentiation of mesoblastic nephroma from Wilm's tumor and sarcomas is discussed. Results of an electron-microscopic study of one of the tumors are given.
