Long‐Term Dermoscopic Evolution of Reticular Erythematous Mucinosis: Case Report

Reticular erythematous mucinosis is a rare dermatosis with a challenging diagnosis. To date, its dermoscopic features have not been well characterised in the literature. Only a limited number of case reports have described dermoscopic findings that may be indicative of the disorder, including the presence of dotted and linear vessels, as well as homogeneous, structureless yellowish‐white areas. The authors would like to emphasise the importance of dermoscopy in the preliminary assessment of erythematous–infiltrative dermatoses, as a non‐invasive diagnostic tool that complements clinical and microscopic examinations.
