Small plaque parapsoriasis (SPP) is a skin disease that is characterized by scaly, slightly raised, and red patches or plaques. It is a type of parapsoriasis, which is a group of skin disorders that resemble psoriasis.

Symptoms

The main symptom of small plaque parapsoriasis is the presence of small, round or oval patches on the skin. These patches are usually less than 5 cm in diameter. They are often red or pink in color and may be slightly raised. The patches are usually covered with a thin layer of scale. The patches may be itchy, but this is not always the case.

Causes

The exact cause of small plaque parapsoriasis is unknown. However, it is thought to be related to an abnormal response of the immune system. Some researchers believe that it may be a precursor to cutaneous T-cell lymphoma, but this is not yet proven.

Diagnosis

The diagnosis of small plaque parapsoriasis is usually made based on the appearance of the skin lesions. A skin biopsy may be performed to confirm the diagnosis and to rule out other skin conditions.

Treatment

The treatment of small plaque parapsoriasis is usually aimed at relieving the symptoms. This may include the use of topical corticosteroids, phototherapy, or retinoids. In some cases, systemic therapy may be needed.

Prognosis

The prognosis for small plaque parapsoriasis is generally good. The condition is usually not life-threatening, but it can be chronic and may require long-term treatment.
