title: Granular cell myoblastoma. Review of the literature and report of a case.
abstract: The origin and nature of granular cell myoblastoma (GCM) have been debated since the original description of a granular cell tumor by Abrikossoff in 1926. Many cell types have been implicated in its histogenesis, including muscle cells, histiocytes, fibroblasts, neural sheath cells and undifferentiated mesenchymal cells, but the origin of the lesion remains still controversial. The authors present a review of the clinical features and the histopathologic and histochemical findings of this nebulous entity. They also report a case of granular cell myoblastoma of the tongue.
