[Rhabdomyosarcoma of the skin--behavior of single tumor cells in vitro].

In vitro growth of individual tumor cells is described, deriving from a rhabdomyosarcoma. There can be suggested two different cell-types: fibroblast-like cells with no particular aspects of morphology, and epitheloid-like cells, recognized from structure and nuclear-behaviour as tumor-giant cells. This methods advantages are discussed as a supplement of histological criteria, as well as its clinical pattern in future.
