During more recent years, these tumors have formed the basis of a number of careful reports, through which the classification, based on histogenesis, should become simplified. Unfortunately, there is still some difference of opinion as to the origin of several testicular tumors which show undoubted histologic differences. Ewing,1 in 1911, made a painstaking analysis of the previously reported cases, from which and from the study of nineteen cases of his own, he reached conclusions which, if they could be fully accepted, would greatly simplify matters.
