Patient with triple negative breast cancer under chemotherapy before ECT. The patient was previously under treatment with taxanes, carboplatin and eribulin. In contrast to response in liver and lung metastasis, skin metastasis showed progression.

Two month after ECT. Good tumour control in the pretreated area was obtained but progression in the border is visible and partially with tumour-free area. Typical hyperpigmentation following ECT treatment is visible.
