Large plaque parapsoriasis explained

Large plaque parapsoriasis
Synonyms:	Parapsoriasis en plaques^[1]

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 10abbr=onNaNabbr=on or larger in diameter. 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]

Treatment

Parapsoriasis treatment consists primarily of light therapy (more specifically PUVA therapy or UVB therapy) possibly in combination with topical steroids. ^[4] Large plaque parapsoriasis is usually a chronic condition that needs long-term treatment.^[5]
