Abstract

Male breast cancer is reported to compromise 0.5% of all breast cancers and 0.16% of malignant cancers in men. The histologic patterns of breast cancer in men are similar to those observed in the female breast. We have experienced 9 cases, among 1345 cases, surgically treated breast cancer, from Jan. 1970 to Dec. 1994. The clinical analysis of 9 male breast cancer who had been treated surgically, was done. The results were as follows: 1) In the age distribution, the peak age incidence was 5th decade (56%). 2) The most common symptom and sign was palpable breast mass(78%: 7 cases). 3) The most common duration of symptom, was within lyear(44%: 4cases), 4) In the location and size of tumor, upper quadrant was 56% (5cases) and central: 2 cases, lower outer: icase, multicentric: 1case. T: 4cases T 2cases T,; 1case Tis: 2cases 5) In the operation method, modified radical mastectomy was performed 88%(7cases), wide excision was 12%(2cases) 6) In the pathologic classification, infiltrating ductal carcinoma was 56% (5cases), intraductal carcinoma 2cases, mucinous carcinoma 1cases, papillary carcinoma 1case. 7) In the stage(AJCC, 1988), stage II was 44%(4cases), stage III 2cases, stage I: 1case, stage 0: 2cases 8) In the follow-up 3 patients died after 10 months, 5years, I lyears survival, each cause of death, was recurrence and distant metastasis, sudden aneurysmal rupture, gastrectomy(stomach cancer). other 6 patients are in the disease free state.
