Diseases, or specifically malignant neoplasms, of the male breast, are sufficiently common to be of interest to the practitioner of medicine, of significance to his patients and of importance to the surgeon. To many members of the medical profession, as well as to the layman, cancer of the male breast erroneously appears rather as a myth, and therefore inconsequential.
The literature on cancer of the male breast is interesting and instructive, but there is no intent to cover it in detail in this article. From it, however, critical and pertinent remarks gleaned here and there will be used to substantiate my findings and to emphasize certain points. Many of the almost 200 articles that I have read on the subject deal with case reports, statistical compilations or clinical studies, and not with laboratory, or more specifically histologic, observations, the criteria around which the discussion in this paper will be constructed.
