title: [Histological and ultrastructural characteristics of Abricosov metastasizing tumor].
abstract: An observation of granular cell Abrikosov tumor metastasizing into lymph nodes is presented. The diagnosis was confirmed by electron microscopy. The ultrastructural features of the tumor confirming its neurogenic origin are described. This is indicated, in particular, by the similarity of the tumor cells with lemmocytes, detection of a basal membrane in some of them, as well as the presence of axonlike projections. The content of some cytoplasmic inclusions was found to be an accumulation of microtubules.
