Correlation of dermatofibroma
|Description||This chapter describes correlation of dermatofibromaDermatofibromas are hard solitary slow-growing papules (rounded bumps) that may appear in a variety of colours, usually brownish to tan; they are often elevated or pedunculated. A dermatofibroma is associated with the dimple sign; by applying lateral pressure, there is a central depression of the dermatofibroma.|

A central white patchCentral white structureless area is a white structureless areahomogenous pattern various diagnoses 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 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).
