Guttate psoriasis is a type of psoriasis that is characterized by small, tear-drop-shaped patches of red, scaly skin.
It is most commonly diagnosed in children and young adults and is estimated to affect around 2% of all people with psoriasis. The exact cause of guttate psoriasis is unknown, but it is believed to be related to genetic and environmental factors. One of the most common triggers for guttate psoriasis is a bacterial infection, such as streptococcal pharyngitis. Other triggers may include stress, injury to the skin, or medications.
The symptoms of guttate psoriasis can vary from person to person but typically include small, red, scaly skin patches often covered in a fine scale. These patches can be itchy and uncomfortable and may spread rapidly to other body parts. In some cases, guttate psoriasis may also cause joint pain and swelling.
