BACKGROUND/AIM: Chronic lower limb ischaemia is a peripheral arterial disease (PAD) which is typically instigated by atherosclerotic plaques in the peripheral vasculature. This article reports on a unique case of chronic ischaemia in the lower limb, presenting in a distinctive manner as a fungal toenail infection.
CASE REPORT
An 82-year-old frail woman with multimorbidity presented with toenail symptoms in her right foot. While initial examination had shown onychomycosis, further investigation was unexpectedly consistent with chronic ischaemia in the lower limb. We explored the clinical presentation, diagnostic challenges encountered, and the subsequent management of this unique manifestation in the context of the patient's multimorbidity.
CONCLUSION
This case report highlights the need to consider chronic limb ischemia as a differential diagnosis in toenail infections when no alternative causes or predisposing factors are identified.
背景/目的：慢性下肢缺血是一种外周动脉疾病（PAD），通常由外周血管中的动脉粥样硬化斑块引发。本文报告了一例下肢慢性缺血的独特病例，其表现为一种独特的真菌感染性趾甲感染。
病例报告
一位 82 岁体弱多病的女性出现右脚趾甲症状。虽然最初的检查显示为甲真菌病，但进一步的检查却意外地显示出下肢慢性缺血。我们探讨了这种独特表现的临床表现、遇到的诊断挑战以及在患者多种合并症的背景下的后续管理。
结论
本病例报告强调了在未发现其他病因或诱发因素的情况下，当出现趾甲感染时，需要考虑慢性肢体缺血作为鉴别诊断。
