title: Comparison of a human granular cell tumour (myoblastoma) with granular cell tumours (meningiomas) of the rat meninges--an immunohistological and ultrastructural study.
abstract: A single human granular cell tumour (myoblastoma) was compared with seven rat granular cell tumours (meningiomas) of the meninges. The comparison was made histologically, ultrastructurally and using immunocytochemical markers. A selection of antibodies to histiocytic, muscle, neural, neural crest and mesenchymal antigens was used. Histogenesis of both the human and rat tumours from neural crest-derived cells was evident and it is suggested that the term 'meningioma' for these rat tumours is a misnomer.
