[A Case of Advanced Breast Cancer in Which Mohs' Paste and Systemic Drug Therapy Allowed Local and Disease Control].

Local control of disintegrating advanced breast cancer is often difficult because of the exudate, bleeding, and the foul odor. The current author encountered a case of large breast cancer with ulceration in which drug therapy and local control with Mohs' paste allowed disease control. The patient was a 61-year-old woman. There was a large ulcerated lump in her right breast, and exudate, bleeding, and a foul odor were present. The woman was diagnosed with hormone-sensitive mucinous carcinoma based on a biopsy, and diagnostic imaging revealed axillary lymph node metastasis and multiple metastases in both lungs. Mohs' paste was used locally, and local control was achieved after 1 month. A year and a half after the start of systemic drug therapy, the breast lump disappeared, and lung metastases and lymph node metastasis had almost disappeared. A CR has been maintained 3 years and 5 months later. Mohs' paste was extremely useful in achieving local control of exudation and bleeding from exposed unresected cancer. This was an excellent treatment in the patient's terminal stages and as part of local treatment in combination with systemic drug therapy.
