[The morphology of tumor-like formations and tumors of the breasts in men and women].

The paper deals with the study of 159 males with gynecomastia and 79 males with carcinoma of the mammary gland and 85 females suffering cancers of the same organ. Gynecomastia presented as diffuse (33.3%) or focal (66.7%). Males and females revealed mammary gland carcinomas of the identical type. Cancers in males were more pernicious than in females. A direct correlation was established between tumor malignancy and frequency of both regional distant metastases. The most unfavorable prognosis was registered in cases of blood and/or lymph vessel invasion.
