Background

Metastatic cutaneous lesions are seen more commonly in breast cancer than in any other malignancy in women, exceeding 20% of all cutaneous metastases.[1] The presence of skin metastases signifies widespread systemic disease and a poor prognosis.[2] Patients present with a variety of symptoms ranging from non-painful, single or multiple, hard, firm, indurated skin to tiny seed-like solid papules and large egg-sized lesions, with sometimes an edema of the skin of the breast, known as the orange peel sign, without any specific clinical diagnostic criteria. The chest wall, the abdomen, the back, and the upper extremities are common sites.[3]

Assessment of cutaneous metastatic disease after mastectomy can be perplexing because the clinical presentation appears similar to other skin diseases such as cellulitis or lymphedema.[1] Although dermoscopy may provide a useful method for the differentiation between the diagnosis of metastasis to the skin and non-neoplastic dermatological diseases or other malignancies, the dermoscopic patterns of breast cancer metastases have not been well described.

We report two cases of breast cancer metastases with an emphasis on the dermoscopic patterns of the disease.
