For more than twenty years I have been acutely sensible of the fact that certain globular cancers of the breast present a particularly bad prognosis. In addition to their external form, they present a varied histologic structure which requires the assumption of a wide latitude of cell metaplasia to keep them within the group of epithelial tumors.
