[Herpes zoster in 2 sisters].

Transmission of herpes zoster infection from one sister to the other is described, resultant from close everyday contacts. Clinical manifestations of the disease (severity, dissemination, course and type of involvement) were much more marked in the elder sister, suffering from disseminated Darier's dyskeratosis and marked debility. Herpes was complicated with vasculitis, necrosis, Pseudomonas aeruginosa infection, development of pneumonia and keratitis. Problems of treatment of such patients are discussed.
