Dermoscopy of lipidised dermatofibroma: A morphological study of 13 cases

Abstract

Background/Objectives

The aim of this study was to evaluate the morphological findings of lipidised dermatofibromas under dermoscopic observation.

Methods

Dermoscopic examination of 13 cases of lipidised dermatofibromas was performed to evaluate specific dermoscopic criteria and patterns.

Results

The most frequently occurring dermoscopic features were as follows: (i) A yellowish homogenous pigmentation in all cases (100%); this pigmentation was total in 30.7%; (ii) White structures were seen in 46.1%, most of them were central white networks (38.4%); (iii) Pigment network was observed in 53.8%, most of them were peripheral delicate pigment networks (38.4%), but two cases showed an atypical pigment network; (iv) The presence of vascular structures was common (10 cases, 77%); (v) Regarding to dermoscopic patterns, five lipidised dermatofibromas (38.4%) showed a total yellowish homogeneous pattern; 38.4% an atypical pattern and 23.2% a 'central white network + peripheral delicate pigment network' pattern.

Conclusions

The dermoscopic recognition of a total yellowish homogeneous area or a yellowish colouration in the context of a dermatofibroma can be proposed to help suspecting a lipidised dermatofibroma.
