Annular erythema of infancy (AEI) is characterized by self-limited eruptions of erythematous, annular to polycyclic patches and plaques, the etiology of which is thought to involve a hypersensitivity reaction to an unknown antigen. We present a case of AEI mistaken for systemic mastocytosis due to elevated serum tryptase. We were unable to find prior reports of an association between AEI and elevated tryptase in the literature.
婴儿环状红斑(AEI)的特征为局限于环状、多环状的红斑性斑块和斑疹,其病因被认为涉及对未知抗原的超敏反应。我们报告了一例因血清胰蛋白酶升高而误诊为全身性肥大细胞增多症的 AEI 病例。我们未能在文献中找到 AEI 与胰蛋白酶升高之间存在关联的先前报告。
