Guttate psoriasis is a distinctive acute skin eruption characterised by small drop-like, salmon-pink papules which usually have a fine scale. A history of an upper respiratory infection secondary to group A beta haemolytic streptococci often precedes the eruption by 2-3 weeks. Guttate psoriasis may be chronic and unrelated to streptococcal infection. Cultures: bacterial culture of the throat or perianal area. To treat or not to treat?

The role of streptococcal infection in the initiation of guttate psoriasis. Perianal cellulitis associated with group A streptococci. Guttate psoriasis (GP) typically occurs following an acute infection such as streptococcal pharyngitis. Obtaining a group A streptococcal molecular probe or culture may serve as a prognostic tool, as physicians should recognize that GP flares associated with a positive result indicate a favorable prognosis.
This is the first study using two-dimensional gel electrophoresis to compare global protein expression patterns in lesional and non-lesional skin from subjects with acute guttate psoriasis associated with streptococcal throat infection and chronic plaque psoriasis. Guttate Psoriasis is self limited over weeks to months, though it may recur, and about one-third of patients may progress to chronic plaque psoriasis. A thorough physical exam is helpful, because many patients infected with Streptococcus will have erythema of their pharynx and perianal areas. Limited studies have shown no benefit with antibiotics, though some dermatologists may recommend a penicillin or cephalosoporin if Group A Streptococcus is suspected. Culture Throat culture for group A -hemo- lytic streptococcus infection. Acute Guttate Psoriasis Any maculopapular drug eruption, secondary syphilis, pityriasis rosea.
Acute Guttate Psoriasis Associated With Streptococcal Perianal Dermatitis
Streptococcal perianal dermatitis and guttate psoriasis. BACKGROUND: The link between guttate psoriasis and streptococcal infection is acknowledged. Group A beta-haemolytic streptococcus was found during bacterial examination of the anal region. Infectious perianal dermatitis is in fact a group of diverse diseases that are characterised by anal and/or peri-anal inflammation in children. Perianal streptococcal dermatitis affects boys more often than girls, usually around the age of five, and diagnosis can be significantly delayed. It develops 24 to 48 hours after acute afebrile pharyngitis. Some cases of perianal streptococcal dermatitis in children may be linked to guttate psoriasis developing, as the bacterial exotoxin behaves like a superantigen and encourages psoriasis to develop 6.
