Treatment with vemurafenib, a small-molecule BRAF inhibitor, has led to dramatic regression of metastatic melanomas harboring a V600E BRAF mutation. As with other kinase inhibitors, the use of vemurafenib has been accompanied by several dermatologic adverse effects. We describe a patient who experienced exacerbation of preexisting acantholytic dyskeratosis in a dose-dependent manner shortly after starting vemurafenib treatment. This was subsequently complicated by Kaposi varicelliform eruption and cessation of the drug treatment owing to progression of the disease.
