Neonatal herpes simplex virus (HSV) infections are serious infections that usually occur in the first few weeks of life. Infants generally present with mucocutaneous lesions, central nervous system infection, and/or systemic disease. In this case report, we describe a set of twins that had unexpected presentations of neonatal HSV. Twin A was diagnosed incidentally on routine eye exam, and Twin B was diagnosed only because his twin was found to be infected; both infants were still hospitalized and were beyond 1 month of age. These twins exhibited atypical manifestations that diverge from the 3 main categories of neonatal HSV and expand our understanding of the spectrum of disease.
