Elongated Linear Vessels Simulating Branching Vessels and Diffuse Structureless Orange Areas As Prominent Dermoscopic Features of Diffuse Flat Facial and Extrafacial Granuloma Faciale: A Case Series

Dermoscopy can be an important help for the diagnosis of skin cancers and inflammatory cutaneous diseases. The list of the dermoscopic features reported in granuloma faciale is wide and includes vascular and non-vascular features. We report here three cases of diffuse flat facial and extrafacial granuloma faciale that exhibited elongated linear vessels simulating branching vessels and diffuse structureless orange areas. The differential diagnosis between flat-type granuloma faciale, basal cell carcinoma and cutaneous sarcoidosis can be extremely difficult, making histology mandatory before any treatment.
