title: [Mitotic regime of various spindle cell sarcomas and their differential diagnosis].
abstract: The mitotic regime was studied in 34 spindle-cell sarcomas of soft tissues, including 11 synovial, 13 low-differentiated fibrosarcomas, 5 leiomyosarcomas and 5 rhabdomyosarcomas. The compared neoplasms were found to differ in the degree of cell proliferation disorders (the mitotic activity, a preponderance of dividing cells at the stage of metaphase, the frequency of pathological mitoses and correlation of their different forms). It is shown that bridges are one of the features of the mitotic pathology for spindle-cell sarcomas, moreover myogenic sarcomas are characterized by a higher incidence of those mitotic disorders which occurrence is conditioned due to damaging of the mitotic apparatus (three group, multiple metaphases, c-mitoses, multipolar and monocentric mitoses).
