Clinical features of Galli–Galli disease, hyperpigmented slightly scaly papules

Galli–Galli disease is a type of Dowling-Degos' disease, a reticulate pigmentary disorder.[1] It presents with many small hard red-brown bumps 1mm to 2mm is size, laid out in a lace-like pattern.[1] These typically occur in skin folds such as the underarms and neck, but also the arms, chest, hands, legs and groin.[1]

The condition runs in families.[1] The disease is also characterized by slowly progressive and disfiguring reticulate hyperpigmentation of the flexures, clinically and histopathologically diagnostic for Dowling-Degos disease but also associated with suprabasal, nondyskeratotic acantholysis.[2][3]

It is rare.[1]
