Could you provide a brief overview of 'Large plaque parapsoriasis' in a medical context?
Large plaque parapsoriasis  are skin lesions that may be included in the modern scheme of cutaneous conditions described as parapsoriasis. These lesions, called plaques, may be irregularly round-shaped to oval and are 10 cm (4 in) or larger in diameter. They can be very thin plaques that are asymptomatic or mildly pruritic. 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.
