Medical Care
- Effective treatment depends on treatment of the underlying tumor. Palliative care is given if lesions are asymptomatic and the primary cancer is untreatable. This care includes keeping lesions clean and dry and debriding the lesions if they are bleeding or crusted. Hydrocolloid dressings may be used to help prevent secondary infection.
- Studies indicate that imiquimod 5% cream (Aldara) may lead to regression of metastasis in some cases of melanoma.
- Liquid nitrogen cryotherapy, photodynamic therapy, and conventional surgery also may be useful for palliation of skin metastasis.
- Short wavelength radiation therapy may be helpful to provide symptomatic relief for painful lesions, using superficial electron beam therapy. Cryotherapy with temperature probe control, carbon dioxide laser therapy,[9, 10] electrochemotherapy,[11] and other treatment approaches may also be of value. Pulsed dye laser may be of value to reduce blood flow to highly vascularized metastases. Intralesional chemotherapy and cytokines can be helpful, and topical retinoids or immune modulators, such as imiquimod, offer promise in select cases.
Surgical Care
In many cases, cutaneous metastasis can cause disfigurement or social embarrassment, or they can diminish the quality of the patient's life. Excision and removal of metastasis may be warranted to enhance the patient's quality of life, but excision of select metastases does little to increase survival. Simple excision is usually the treatment of choice.
