In October 2006, a 70-year-old Japanese woman came to our hospital for evaluation of her severe itching accompanied by nodular skin lesions on the trunk and extremities (Figure 1A), symptoms that clinically suggested prurigo nodularis. There were no blister formations at the time of initial presentation, but several small blisters sometimes appeared on the extremities during the course of the disease (Figure 1B).
