Correlation of dermatofibroma
From dermoscopedia
Central white patch
A central white patch is a white structureless area located in the center of a lesion (Kittler et al., 2016a). Histopathologically, this feature corresponds to fibrosis in the papillary dermis (Zaballos et al., 2008).
Peripheral delicate network
Peripheral delicate network are thin brown lines forming a meshwork pattern in the periphery of a lesion. Histologically, it corresponds to hyperpigmentation of basal keratinocytes. A central white patch together with a peripheral delicate network is highly suggestive for dermatofibroma (Zaballos et al., 2008).
