A novel association of pseudoainhum and epidermolytic ichthyosis, successfully treated with full thickness skin graft after failed z-plasty repair.

Pseudoainhum is a rare constriction band variant thatmay progress to spontaneous digital strangulationand auto-amputation. Although its association withpalmoplantar keratodermas is well established, ithas not been reported in conjunction with classicepidermolytic ichthyosis. We describe the first suchcase in a 25-year-old woman who presented witha painful constricting band of the fifth toe. We alsodescribe her treatment course, which consisted ofa failed z-plasty, the traditional therapeutic optionfor acute pseudoainhum, and report the success ofsubsequent full thickness skin graft, suggesting thebenefit of this procedure as a therapeutic alternativefor patients with pseudoainhum.
