Generalized Dowling-Degos Disease: Case Reports
نویسندگان
چکیده
Dowling-Degos disease (DDD) is a rare autosomal dominant trait characterized by numerous, symmetrical, progressive and pigmented macules over the axillae, groins, face, neck, arms and trunk as well as scattered comedo-like lesions (dark dot, follicles) and pitted acneiform scars. Histopathology is diagnostic testing using a distinctive form of acanthosis, characterized by an irregular elongation of thin branching rete ridges, with a concentration of melanin at the tips. We report cases of generalized DDD in a single family with autosomal dominant penetrance. DDD can be presented in a generalized form with hypopigmented lesions instead of reticulate hyperpigmentation confined to the flexor areas. This form can be differentiated from DUH by histopathology.

متن کاملGeneralised Dowling-Degos Disease: A Rare Variant with Hypopigmented Macules
Dowling Degos disease is characterised by hyperpigmented macules arranged in a reticulate pattern in the flexures. The rare hypopigmented variant shows characteristic acanthosis with antler like rete ridges but with pigment only at the tips of the rete ridges. We describe here a rare variant with coexistence of characteristic reticulate hyperpigmentation and hypopigmented macules, which has bee...
