Guttate psoriasis (also known as eruptive psoriasis ) is a type of psoriasis that shows small lesions (0.5-1.5 cm) above the upper trunk and proximal extremities; it is often found in young adults. The term "guttate" is used to describe skin lesions that resemble lesions. Guttate psoriasis is classically triggered by a bacterial infection, usually an upper respiratory tract infection.

Signs and Symptoms
Usually guttate psoriasis erupts after a throat infection, or a sore throat. Initially, when a throat infection has healed, the person may feel fine for several weeks before realizing the appearance of red spots. They look small at first, like dry red dots that are slightly itchy. When scratched or picked up the top layer of dry skin will be removed, leaving dry, red skin underneath with white, dry areas mark where the dry skin flakes stop and start. In the following weeks, the dots can grow up to an inch in diameter. Some of the larger ones can form a pale area in the middle that is slightly yellow.
Guttate psoriasis can occur in any part of the body, especially the legs, arms, torso, eyelids, back, down, bikini-line and neck. The number of lesions can range from 5 to more than 100. Most commonly affected body parts are seen on the arms, legs, back and body.

Cause
Genetic and environmental factors may predispose to guttate psoriasis. Human leukocyte antigens, especially those in the HLA-C group are associated with skin disorders. Beta-haemolytic streptococcal infarction is a contributing major environmental factor. The typical infection route is the upper respiratory system. Rarely is also caused by a skin infection around the anus (perianal streptococcal dermatitis).
Diagnosis
Guttate psoriasis can usually be diagnosed by clinical examination alone.
Management
Treatments used for plaque psoriasis can also be used for guttate psoriasis. Some studies specifically focus on guttate psoriasis management, so there are currently no strong guidelines for managing different guttate psoriasis from plaque psoriasis. Because the role of streptococcal infection plays in the development of guttate psoriasis, systemic antibiotics have been considered a potential treatment option. Although systemic antibiotics may be considered to treat initial infection at the source, there is no support for its use in the management of guttate psoriasis itself, nor is there evidence for prophylactic tonsillectomy use. This condition often usually disappears by itself in a few weeks to months, and only about one-third of patients will have chronic plaque.
Epidemiology
Treat psoriasis accounts for about 2% of cases of psoriasis.
