Dactylolysis spontanea or ainhum involving the big toe.

Abstract

We describe the case of an Italian Caucasian man with ainhum involving both big toes. Ainhum or dactylolysis spontanea is characterized by the development of a constricting band around a toe, which progresses to spontaneous autoamputation. It usually affects the fifth toe bilaterally, but in rare cases other toes may be involved. The disease occurs in Black people living in tropical regions but occasionally has been reported in persons having fair skin.
