title: [Melanoma with a rhabdopoietic differentiation (ectomesenchymoma)].
abstract: This is the first description in Russian literature of histological and electron-microscopic structure of an exophytic skin mesenchymoma with melanocytic and rhabdomyopoietic differentiation. The presence in the tumour of cells-hybrids possessing the two differentiations allows one to suppose a histogenetic link of this tumours with pluripotential cells of neuroectoderm.
