Dermatofibroma with vascular structures
A 54-year-old woman consulted for a firm reddish tumor on her left thigh. Dermoscopy revealed a central scarlike white patch in favor of a dermatofibroma and peripheral vascular structures: peripheral erythema and linear-irregular vessels.
peripheral erythema and linear-irregular vessels
Vascular structures are found in 29 to 49% of dermatofibromas, including erythema, dotted vessels, coma vessels, hairpin vessels, glomerular vessels, telangiectasias, linear-irregular vessels, polymorphous/atypical vessels.
