Despite the name, parapsoriasis is not related to psoriasis. In small plaque parapsoriasis, slightly reddened patches or streaks are seen over the trunk, less often in the upper extremities. The surface may be slightly scaling. The eruption resembles mild eczema or even pityriasis rosea but is mostly asymptomatic and invariable. In large plaque parapsoriasis, the patches are larger and there are less of them. The large plaque form may precede cutaneous T-cell lymphoma, i.e. mycosis fungoides. In the small plaque variant this is very uncommon. The diagnosis should be confirmed in hospital.
