Since a skin infiltration of breast cancer may increase hemorrhage and malodorous exudates, it significantly reduces the quality of life. Local treatment is usually performed with zinc oxide starch, Mohs paste or its alternatives. However, the Mohs paste causes pain due to necrobiosis of normal tissues, while the topical therapy with zinc oxide starch ineffectively suppresses hemostasis and odor. We hereby report a case of an 86-year old woman with skin infiltration by breast cancer. The patient’s symptoms including bleeding, infection signs, odor, exudates, necrotic tissue objectively improved with Shiunko ointment, Zinc oxide starch, and Metronidazole (MNZ) combination therapy. The gauze was exchanged once a day and this treatment was simple and easy. The combination therapy with Shiunko ointment, Zinc oxide starch, and MNZ may become an effective new regimen for bleeding and odor from skin involvement in breast cancer.
