Large plaque parapsoriasis (also known as "parapsoriasis en plaques") 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 symptomatic 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.

Parapsoriasis treatment consists primarily of light therapy (more specifically PUVA therapy or UVB therapy) possibly in combination with topical steroids. Large plaque parapsoriasis is usually a chronic condition that needs long-term treatment.
