Abstract

Ultrastructural findings in 2 cases of actinic granuloma are presented. The changes observed at the periphery of the lesion and in the elastic fibers, with early stage of damage, were similar to those described in actinic elastosis. Later, an histiocytic reaction which was apparently directed against damaged elastic fibers was observed. The ultrastructure confirms the light-microscopic findings, but does not clarify the etiology of the lesion or its relation to granuloma annulare.

摘要

本文报告了2例光化性肉芽肿的超微结构研究结果。在病变周边及弹性纤维中观察到的早期损伤变化，与光化性弹性组织变性中所描述的相似。随后，观察到一种明显针对受损弹性纤维的组织细胞反应。超微结构证实了光镜下的所见，但未能阐明该病变的病因或其与环状肉芽肿的关系。
