Macro-micro dermatology: erythematous papules and lentigo-like macules--a new entity?

Galli-Galli disease is usually characterized by reticulate hyperpigmentation of the flexures. Rare patients may present without this finding, instead having only localized erythematous papules and brown, lentigo-like macules on the trunk and extremities. Histological changes consist of elongated and in part hyperpigmented rete ridges and areas of acantholysis.
