Large plaque parapsoriasis are skin lesions that may be included in the modern scheme of cutaneous conditions described as parapsoriasis.[2] These lesions, called plaques, may be irregularly round-shaped to oval and are 10 cm (4 in) or larger in diameter.[2] They can be very thin plaques that are asymptomatic or mildly pruritic.[2][3] Large-plaque parapsoriasis is a common associate of retiform parapsoriasis, can be accompanied by poikiloderma vasculare atrophicans, and can in rare occasions be a precursor to cutaneous T-cell lymphoma.[2]
