title: [A Case of Breast Metastasis of Eccrine Porocarcinoma].
abstract: An 80's woman was diagnosed with eccrine porocarcinoma of the head in 2010.T he tumor was removed surgically but relapsed in the cervical and axillary lymph nodes 2 years later.The patient underwent surgery, and received systemic chemotherapy and radiation.Chest CT after treatment revealed an irregular mass and thickened skin in the left breast.Core needle biopsy specimens were used to diagnose metastasis of eccrine porocarcinoma.A wide excision with a 1 cm margin was performed under local anesthesia.After surgery, supraclavicular lymph node recurrence was detected.The patient received palliative care because there was no effective treatment available.Eccrine porocarcinoma is a rare malignant tumor of the intraepidermal sweat duct.Breast metastasis from malignant disease is also rare.To our knowledge, breast metastasis of eccrine porocarcinoma has not been reported.
