Abstract: Objective:To study the clinical features of skin metastatic carcinoma,and to provide the reference for its diagnosis and treatment. Methods:The clinical materials of one case of cutaneous metastases complicated with herpes zoster were analyzed and the related literatures were reviewed.The right chest wall in the patient appeared erythema and blisters with pain 4 months ago;in the local hospital the patient was diagnosed as herpes zoster and received relevant treatment;the pain was improved,but there were still erythema,papules and nodules in the local area.The skin lesions were erosive,expanded and deepened rapidly 20 days ago,and the pathological examination,lung CT,abdominal CT and other assistant examinations were performed in our hospital. Results:The lesion biopsy results showed invasive carcinoma with extensive infarction.The results of lung CT,abdominal CT and other assistant examinations showed the right breast occupying lesions complicated with cervical lymph nodes,liver,pleural and bone metastases.The skin lesions were improved after local treatment and 2 courses of chemotherapy(docetaxel combined with trastuzumab), but failed to heal completely. Conclusion: Skin metastatic carcinoma is rare,and its clinical manifestations are different.The clinicians should master the regularity of the disease,timely conduct the histopathological examination and the related examination in the other parts to reduce the incidence of misdiagnosis and missed diagnosis.
