Chronic varicella-zoster skin infection complicating the congenital varicella syndrome.

Congenital varicella is a rare syndrome arising when a pregnant woman develops varicella before the 24th week of pregnancy. We report an occurrence of congenital varicella syndrome complicated by a chronic varicella zoster virus skin infection in an immunocompetent infant. The chronic verrucous skin infection is puzzling in our patient, as this disease is usually described in immunosuppressed patients.
