Abstract
Jacquet's erosive dermatitis (JED) is a severe irritant dermatitis characterized by erosive genital and perianal lesions, often misdiagnosed due to overlapping clinical features. This case report presents two adult cases of JED with distinct clinical and dermoscopic findings. Dermoscopy revealed a characteristic polymorphic vascular pattern, including short linear, curved, coiled, dotted, and globular vessels, aiding in the diagnosis and differentiation from similar conditions. These findings highlight dermoscopy's utility as a non-invasive diagnostic tool for JED, potentially reducing the need for biopsy.
