Kaposi's varicelliform eruption is characterized by disseminated vesiculopustules and erosions caused by a herpes virus infection superimposed on a pre-existing dermatosis. The eruption usually occurs in individuals with atopic dermatitis or other pre-existing dermatosis such as Darier's disease, pemphigus foliaceus, mycosis fungoides, Sézary syndrome, benign familial pemphigus, ichthyosis vulgaris, second-degree burns, multiple myeloma, and Grover's disease. We report here a new case of Kaposi's varicelliform eruption in a 38-year-old woman with rosacea. To our knowledge, this is the first case of Kaposi's varicelliform eruption associated with rosacea to be reported.
