Cutaneous elastofibroma is part of the connective tissue nevus complex. Two subungual cases remotely similar to the one presented here have been described before. This patient presented with an unusual form of subungual elastofibroma of the big toe, which was surgically removed. Histopathology revealed a connective tissue tumor extremely rich in very fine elastic fibers. Their relationship to oxytalan and elaunin fibers is discussed as is the potential association of this nail bed lesion with the onychodermis.
皮肤弹力纤维瘤是结缔组织痣复合体的一部分。之前曾描述过两例与本文所呈现病例有一定相似之处的甲下病例。该患者表现为一种不寻常的大脚趾甲下弹力纤维瘤，已通过手术切除。组织病理学显示为一种结缔组织肿瘤，富含极细的弹性纤维。文中讨论了其与弹力纤维和弹性硬蛋白纤维的关系，以及这种甲床病变与甲真皮的潜在关联。
