Biopsy specimens of papules taken from eight patients with polymorphous light eruption ( PMLE ) were examined by a direct immunofluorescence technique. Extensive intervascular and focal perivascular deposits of fibrin were detected in each case. Slight vascular deposition of C3 and IgM were observed in five and two patients, respectively. The lupus band test was negative in all cases. The findings suggest that venular injury with activation of the clotting system is involved in the development of lesions in PMLE .
采用直接免疫荧光技术对8例多形性日光疹（PMLE）患者丘疹的活检标本进行了检查。在每例病例中均检测到广泛的血管间和局灶性血管周围纤维蛋白沉积。分别在5例和2例患者中观察到轻微的C3和IgM血管沉积。所有病例的狼疮带试验均为阴性。这些发现提示，凝血系统激活所致的小静脉损伤参与了PMLE皮损的发生。
