[A Case of Advanced Breast Cancer with Improvement in the Quality of Life by Local Treatment Using Mohs Paste and Systemic Pharmacotherapy].

Locally advanced breast cancer with skin invasion often causes malodor, bleeding, and massive exudates, which degrades patients' quality of life(QOL). A 61-year-old woman presented with locally advanced breast cancer with malodor and massive exudates, which had carcinomatous pleurisy causing dyspnea. We administered endocrine therapy and chemotherapy and used Mohs paste for local therapy. The exposed part of the tumor was fixed using Mohs paste. After continuing to apply Vaseline over the fixed part, the lesion spontaneously detached without surgical removal and completely epithelized, and malodor and exudates disappeared. Cancerous pleurisy also improved, and dyspnea disappeared. Local treatment using Mohs paste and systemic pharmacotherapy dramatically improved her QOL.
