Amiodarone can occasionally lead to a slate-coloured pigmentation in chronically UV-expose skin. A 63 year old patient presented with a pruritic bluish-purple pigmentation of the face 2 years after taking 400 mg of amiodarone daily for 2 years. During the 24 months after the dose was reduced to 200 mg daily, the pigmentation remained unchanged. Amiodarone pigmentation is caused by the UV-induced accumulation of lipofuscin in dermal macrophages, depending on both the daily dose and the duration of therapy. In the differential diagnosis, pigmentation caused by other drugs is the main consideration. Cessation of therapy eventually leads to complete normalization of skin colour.
胺碘酮偶尔会导致长期暴露于紫外线的皮肤出现石板色色素沉着。一名63岁患者在每日服用400毫克胺碘酮2年后,面部出现瘙痒性蓝紫色色素沉着。在剂量减至每日200毫克后的24个月内,色素沉着没有变化。胺碘酮色素沉着是由紫外线诱导脂褐素在真皮巨噬细胞中积累所致,这取决于每日剂量和治疗持续时间。在鉴别诊断中,主要考虑其他药物引起的色素沉着。停止治疗最终会使皮肤颜色完全恢复正常。
