[Surface architectonics of lymphoid elements in children with lymphoblastic lymphosarcoma].

The following three patterns of cell surface of lymphoid elements were identified in the course of rastr electron microscopic studies carried out in children with lymphosarcoma: marked plicate , relatively smooth and tuberous. No relationship between the pattern of tumor cell membrane and the site of sampling was established. Such diversity of lymphoid element surface pattern in children with lymphosarcoma is suggestive of the varying level of tumor cell differentiation and is, possibly, a manifestation of different stages of lymphocyte development.
