Abstract
Tsunoda et al. first reported that an eruption of herpes zoster sometimes crosses over the midline of the trunk in 1986. We herein report two patients whose eruptions of herpes zoster skipped over the midline of the back along the cutaneous nerves of the other side. Our two cases may have been caused by the anastomosis or crossing of the cutaneous nerves at the midline of the back as described anatomically by Tsunoda in 1982.
