Cutaneous metastases from carcinoma, including breast cancer, are relatively uncommon. Conversely, patients with metastatic breast cancer may develop dermatologic manifestations that represent side effects from anticancer therapies. The most common signs and symptoms include rash, hand-foot syndrome, alopecia, pruritus, paronychia, and onycholysis.
Cutaneous metastases arise most commonly from cancers of the breast, skin, stomach, lungs, uterus, large intestine, and kidneys.
In most cases, cutaneous metastases develop after the initial diagnosis of the primary malignancy (eg, metastases of breast carcinoma involving the chest wall several years after a mastectomy).
