title: Grouping prurigo: report of cases.
abstract: Grouping prurigo was reported as a new clinical entity by Ofuji et al. in 1977 and 1988. No further cases have been reported since. Herein we report four cases of grouping prurigo and discuss the possible relationship between this condition and other diseases in the prurigo group, including chronic pruritic papular dermatitis in adult men, which was reported by Chang et al. in 1999. Since grouping prurigo and chronic pruritic papular dermatitis in adult men share approximately the same characteristics in both clinical and histopathological findings, we concluded that these two disorders may be the same entity, characterized by grouped pruritic solid papules on the trunk.
