다국어 초록 (Multilingual Abstract)

Male breast cancer accounts for less than 1% of all breast cancers. Most common type of male breast cancer is the invasive ductal carcinoma(IDC), which cancer cells of ductal origin break through the wall of the milk duct and invade the tissues of the breast. A 59-year-old male patient presented with a painful protruding erosive nodule with oozing on right nipple, which was found 15 years prior to the visit. Under the impression of malignant melanoma, partial excisional biopsy was done. Pathologist reported that the tissue was confirmed as invasive carcinoma, probably ductal type. The patient was transferred to department of breast surgery, and radical mastectomy of right breast with sentinel lymph node biopsy was done. There was no lymph node metastasis and carcinoma was removed with clear resection margin. The post-operational chemotherapy with docetaxel, cyclophosphamide and tamoxifen has been done to patient and no sign of recurrence showed till now. In this case there was retro-areolar mass on breast of male patient and direct skin invasion of mass was seen. We easily underestimate the possibility of male breast cancer because of its rare incidence and delayed diagnosis of it would increase the chance of metastasis. We should not exclude the possibility of male breast cancer when there`s an abnormal eczematous lesion in nipple. Herein we report a rare case of IDC with direct skin invasion on male breast.
