Abstract

Background: Infiltrative lesions of the skin caused by unresectable malignant tumors reduce the quality of life of patients significantly due to the presence of bleeding, exudate, pain, and/or malodor. Objective: We compared the efficacy of a modified Mohs' technique and topical application of a starch powder containing zinc oxide as palliative treatments for skin lesions caused by unresectable tumors in our hospital. Design: This is a retrospective study. Settings/Subjects: This study included nine patients who were treated for skin-infiltrating lesions caused by unresectable malignant tumors at our hospital in Japan from April 2008 to December 2019. Measurements: Mohs' paste or zinc oxide powder (50%) was applied to the infiltrative skin lesions. Arterial embolization was performed before the application of the Mohs' paste for patients at risk for arterial hemorrhage. Patients were evaluated for pain, tumor size, bleeding, wound exudate, and malodor. Results: Both treatments were useful for alleviating symptoms, such as tumor size, local bleeding, malodor, and exudate in patients with unresectable malignant tumors. Pain was reduced in patients treated with Mohs' paste for 1 hour as compared with those treated for 24 hours. Conclusions: Effective management of skin infiltrative lesions can be achieved by using a modified Mohs' technique, topical application of starch powder containing zinc oxide, and arterial embolization to reduce the vascularization of the tumors.
