Abstract

Reticulated pigrnented anomalies of the flexures is a pigmentary disorder bearing genetic back ground, also known as Dowling Degos disease or dark dot disease. It is characterized reticulated brownish black macules on the flexural areas with the histological features of filiform pigmented epidermal downward proliferation and the presence of intraepidermal keratin containing cysts. We report 34-year-old housewife who showed brawnish black reticulated macules on her axillae, anterior neck and genitocural folds. Pigmented comedones were also found at the marginal areas of the axillae. Biopsy specimen revealed the presence of intraepidermal keratin containing cysts and basilar hyperpigmentation.
