title: Familial ainhum: a case report of multiple toe involvement in a father and son, staging of ainhum with insight into different types of constricting bands.
abstract: Ainhum, also known as dactylolysis spontanea, is a painful constriction of the base of the fifth toe, frequently followed by spontaneous amputation a few years later. The disease is often symmetrical on both the feet, but, occasionally, other toes are also affected and rarely the distal phalanx of the fifth finger. Pseudoainhum is a similar condition that occurs as a secondary event resulting from certain hereditary and nonhereditary diseases that lead to annular constriction of digits. We hereby present a case of familial ainhum in father and son with multiple toes affected, autoamputation, and more involvement of fourth toe than the fifth toe, which is a very rare finding.
