Dermoscopy of Eruptive Syringoma.

Syringoma is a benign adnexal tumor of eccrine origin. Eruptive syringoma (ES) is a rare variant and can mimic other diseases especially lichen planus (LP). The dermoscopic observation of ES is not well described. We report here a case of ES, initially misdiagnosed as LP. The dermoscopic findings showed fine reticulate brown lines on a light brown background contrarily to the findings usually seen in LP. These findings prompt a skin biopsy which subsequently confirmed the diagnosis of ES. The use of dermoscopy in ES can be useful and may help differentiate it from other diseases.
