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.
假断肢是一种罕见的缩窄带变体，可能进展为自发性手指绞窄和自截。尽管其与掌跖角化病的关联已得到充分证实，但尚未见与经典表皮松解性鱼鳞病相关的报道。我们描述了首例这样的病例，患者为一名25岁女性，其第五趾出现疼痛性缩窄带。我们还描述了她的治疗过程，包括一次失败的Z成形术（急性假断肢的传统治疗选择），并报告了随后全厚皮片移植的成功，提示该手术作为假断肢患者的一种治疗替代方法的益处。
