A Classification of the Tumors of the Glioma Group on a Histogenetic Basis with a Correlated Study of Prognosis.

This little book is an attempt to bring "some order out of chaos" in the study of "tumors that are commonly grouped together as gliomas." It is an elaboration of the work that has come out of the Cushing clinic within the last few years. The variations in the clinical pictures in gliomas are well known; the wide differences in the histologic structure and even the gross appearance of these tumors have puzzled all who have had occasion to study them. In this book an effort is made to trace back the histologic structure to embryologic type or types. Twenty different cell types are recognized with fourteen different types of tumors, as follows: medullo-epithelioma; medullo-blastoma; pineoblastoma; pinealoma; ependymoma; neuro-epithelioma, spongioblastoma: (a) multiforme and (b) unipolare; astroblastoma, astrocytoma: (a) protoplasmaticum and (b) fibrillare; oligodendroglioma; neuroblastoma; ganglioneuroma, and papilloma chorioideum. The chapter on histologic methods is too brief, especially for those who
