Galli–Galli disease
Galli–Galli disease is a rare inherited condition that has close resemblance clinically to Dowling-Degos' disease, but is histologically distinct, characterized by skin lesions that are 1- to 2-mm slightly keratotic red to dark brown papules which are focally confluent in a reticulate pattern. 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.
