Guttate psoriasis is a type of psoriasis characterized by the appearance of red, drop-shaped lesions all over the body, being more common to identify in children and adolescents and, in some cases, does not need treatment, just follow-up by a dermatologist.
Psoriasis is a chronic and non-contagious inflammatory disease, which can negatively interfere with a person's life due to the characteristic lesions of the disease, affecting interpersonal relationships and daily activities, even though it is a benign disease.
Causes of guttate psoriasis
The main cause of guttate psoriasis is a bacterial infection, mainly by bacteria belonging to the genus Streptococcus , in which symptoms usually arise after a throat attack.
Guttate psoriasis can also occur as a result of other inflammatory and infectious processes, such as respiratory infections, inflammation of the tonsils, stress and the use of some medications, in addition to being caused by genetic alterations.
Main symptoms
Guttate psoriasis is characterized by the appearance of red lesions on the skin in the form of a drop, which appear on the arms, legs, scalp and trunk, which is more frequent. These injuries can appear overnight and can be in high relief in some people. These lesions can start small and increase in size and quantity over time, and can also itch and peel.
People most at risk for guttate psoriasis are those who have first-degree relatives with chronic psoriasis or who have one or more factors that influence their onset or worsening, such as depression, obesity, diabetes, hypertension, metabolic syndrome, colitis and arthritis rheumatoid, for example.
How is the diagnosis
The diagnosis of guttate psoriasis must be made by the dermatologist, who must evaluate the lesions presented by the person and check the patient's clinical history, that is, if he is using any medication, if he has allergies or other skin diseases.
Although the evaluation of the lesions is sufficient to confirm the diagnosis, the doctor may also request blood tests and, in some cases, a skin biopsy to differentiate it from other diseases and confirm the type of psoriasis.
Treatment for guttate psoriasis
The milder cases of guttate psoriasis do not require specific treatment, as the signs and symptoms of the disease usually disappear on their own between 3 and 4 months. However, the dermatologist may recommend the use of creams, ointments or lotions that must be applied directly to the affected skin.
In addition, the use of corticosteroids and antibiotics and phototherapy with UVB radiation may be indicated in order to relieve symptoms.
