Calciphylaxis is a rare and life-threatening disease characterized by cutaneous arteriolar stenosis and vascular thrombosis leading to skin ischaemia and necrosis. While calciphylaxis occurs mostly in patients with end-stage renal disease, the disorder has been described in patients with normal renal function, namely non-uraemic calciphylaxis (NUC). A 41-year-old African-American woman presented with a painful ulcerative rash on her thighs and right buttock 2 months after undergoing an orthotopic liver transplantation. She underwent debridement of the lesions and an excisional biopsy of one of the lesions, which revealed calciphylaxis. She was treated with sodium thiosulfate, cinacalcet and hyperbaric oxygen with complete resolution of the lesions 4-5 months after presentation. While she was treated with a course of high-dose glucocorticoids after the transplant, she did not have other risk factors for calciphylaxis. NUC should be considered in the differential diagnosis of necrotic skin lesions in postliver transplant patients.
钙过敏是一种罕见且危及生命的疾病,其特征为皮肤小动脉狭窄和血管血栓形成,进而导致皮肤缺血和坏死。虽然钙过敏大多发生于终末期肾病患者,但在肾功能正常的患者中也有该病症的描述,即非尿毒症性钙过敏(NUC)。一名41岁的非裔美国女性在接受原位肝移植2个月后,大腿和右臀部出现疼痛性溃疡性皮疹。她接受了病灶清创术以及其中一个病灶的切除活检,结果显示为钙过敏。她接受了硫代硫酸钠、西那卡塞和高压氧治疗,症状出现4至5个月后病灶完全消退。虽然她在移植后接受了一个疗程的大剂量糖皮质激素治疗,但她没有其他钙过敏的危险因素。在肝移植后患者出现坏死性皮肤病变的鉴别诊断中应考虑非尿毒症性钙过敏。
