A case of constriction band at the fingers arising from keratosis palmoplantaris is reported. Excision of the band and closure of wound by Z-plasties resulted in complete relief of clinical symptoms and vascular insufficiencies. Histologic examination revealed the variability of this skin lesion even in the same patient. The sparsity of keratohyaline matrix in the horn cells in the skin may contribute to the constriction ring formation.
报告了一例由掌跖角化病引起的手指缩窄带病例。切除缩窄带并通过Z成形术闭合伤口后，临床症状和血管功能不全完全缓解。组织学检查显示，即使在同一患者中，这种皮肤病变也存在变异性。皮肤角质形成细胞中透明角质基质的稀少可能有助于缩窄环的形成。
