Small Plaque Parapsoriasis

Small plaque parapsoriasis (pronunciation: smɔːl plækˌpærəsaɪˈoʊsɪs) is a cutaneous condition characterized by scaly, often itchy patches on the skin. It is a type of parapsoriasis, which refers to a group of skin disorders that resemble psoriasis but are less severe.

Etymology

The term "parapsoriasis" is derived from the Greek words "para" meaning "beside" or "resembling", and "psoriasis", a chronic skin disease. The prefix "small plaque" refers to the size and appearance of the skin lesions.

Symptoms

Small plaque parapsoriasis is characterized by small, round or oval patches of red or pink skin, usually less than 5 cm in diameter. The patches are often covered with fine, white scales and can be itchy. They are most commonly found on the trunk, but can also appear on the arms, legs, and other parts of the body.

Causes

The exact cause of small plaque parapsoriasis is unknown. However, it is thought to be related to an abnormal immune response. Some researchers believe it may be a precursor to certain types of non-Hodgkin lymphoma, although this is still a matter of debate.

Diagnosis

Diagnosis of small plaque parapsoriasis is based on the appearance of the skin lesions and a skin biopsy. The condition can be difficult to distinguish from other skin disorders, such as eczema or dermatitis, so a biopsy is often necessary to confirm the diagnosis.

Treatment

Treatment for small plaque parapsoriasis typically involves the use of topical corticosteroids to reduce inflammation and itching. In some cases, phototherapy (treatment with light) may be recommended.
