Other names: Kitamura reticulate acropigmentation[1]

Reticular pigmented anomaly of the flexures (also known as dark dot disease and Dowling–Degos disease) is a fibrous anomaly of the flexures or bending parts of the axillae, neck and inframammary/sternal areas.[2]: 856  It is an autosomal-dominant pigmentary disorder that may appear in adolescence or adulthood. This condition is due to mutations in structural/desmosomal proteins found within stratified squamous epithelium.[3]

Dark dot disease is associated with KRT5.[4]
