We compared the number of mast cells in erythema multiforme lesions, in clinically healthy mucosa between the EM attacks and in healthy mucosa from healthy volunteers. The mast cell count in patients with erythema multiforme was numerically higher than in healthy controls, but the differences were not statistically significant. In erythema multiforme lesions the mast cell count was low in the intensely inflamed superficial lamina propria, but high in normal appearing mucosa between the attacks suggesting local mast cell degranulation in the most intensely inflamed areas.
我们比较了多形红斑病变中、多形红斑发作期间临床健康黏膜以及健康志愿者健康黏膜中的肥大细胞数量。多形红斑患者的肥大细胞计数在数值上高于健康对照组，但差异无统计学意义。在多形红斑病变中，炎症强烈的浅表固有层中肥大细胞计数较低，但发作间期外观正常的黏膜中肥大细胞计数较高，提示在炎症最强烈的区域存在局部肥大细胞脱颗粒。
