Abstract

Dermatofibroma is a proliferation of spindle cells located in the dermis. We used scanning electron microscopy to examine two histologically confirmed lesions and observed preserved collagen bundles in the perilesional area. In the lesional area, the collagen was denser, without formation of bundles. Higher magnification showed collagen with mesh-like appearance similar to stretched tufts of cotton. Very high magnification evidenced the tufts of cotton and spindle cells measuring 2 to 12 microns.

摘要

皮肤纤维瘤是位于真皮层的梭形细胞增殖。我们使用扫描电子显微镜检查了两个经组织学证实的病变，观察到病变周围区域的胶原束保存完好。在病变区域，胶原更致密，未形成束状。更高放大倍数显示胶原呈网状外观，类似于拉伸的棉絮簇。极高放大倍数显示了棉絮簇和大小为2至12微米的梭形细胞。
