This case describes a 63-year-old woman with stage IV lung adenocarcinoma who presented with a painful, initially unilateral, rash on her breast. The clinical appearance of erythematous plaques with vesiculo-papules suggested disseminated herpes zoster, leading to the initiation of intravenous acyclovir. However, histopathology revealed atypical epithelial cells consistent with cutaneous metastasis from the primary lung carcinoma. Although cutaneous metastases from lung cancer typically present as nodules, zosteriform skin metastases are extremely rare. This case is a unique instance of bilateral zosteriform skin metastases from lung carcinoma, underscoring the importance of considering cutaneous metastasis in patients with atypical skin lesions and underlying malignancy. Early recognition and accurate diagnosis are crucial for patient management and prognosis.</p>","PeriodicalId":11040,"journal":{"name":"Dermatology online journal","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144316144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A comprehensive literature search was completed using a combination of keywords: \"topical,\" \"corticosteroid,\" \"non-steroid,\" \"efficacy,\" \"adverse effects,\" \"malpractice,\" and \"inflammatory skin diseases.\" Articles were screened for relevance to topic of safety and efficacy of topical corticosteroids and noncorticosteroid therapies for inflammatory skin diseases.

A screening of the studies resulted in 24 articles that met criteria. The panel unanimously voted to adopt 10 consensus statements and recommendations.
