A Case of Reticulate Pigmented Anomaly of the Flexures (Dowling-Degos Disease) / 대한피부과학회지

ABSTRACT

Reticulate pigmented anomaly of the flexures is a rare autosomal dominant genodermatosis, and this is also known as Dowling-Degos disease. The clinical symptoms are characterized by the progressive evolution of small hyperpigmented macules in a reticulate distribution, and this shows a predilection for the flexural regions, including the axillae, antecubital fossae, inframammary regions, neck and groin. The histopathology of reticulate pigmented anomaly of the flexures typically shows filiform epithelial down-growth of the epidermal rete ridges along with basal hyperpigmentation. We report here on a case of reticulate pigmented anomaly of the flexures in a 45-year-old male who showed multiple, asymptomatic, scaly brownish reticulated macules on the flexural areas.
