Lichenified papules – an unusual cutaneous presentation of metastatic breast cancer

Cutaneous metastases of internal malignancies are uncommon, these lesions typically present as papules or nodules. The presence of cutaneous metastases is significant as underlying internal metastases are present in two-thirds of breast cancers with cutaneous metastases.1
We present the unusual case of a 65 year old woman with a history of primary breast carcinoma, presenting with multiple itchy lichenified papules and plaques. Multiple biopsies identified these lesions as cutaneous metastatic breast cancer deposits. There are no previous reported cases of metastatic breast cancer presenting in this way.
