Insights
Guttate psoriasis can be triggered by streptococcal infections beyond the throat. A case report highlights a child with streptococcal anal infection who developed guttate psoriasis, emphasizing thorough examination.
Area of Science:
- Dermatology
- Pediatrics
- Infectious Diseases
Background:
- Guttate psoriasis is often linked to streptococcal pharyngitis.
- Non-pharyngeal streptococcal infections are less commonly associated with guttate psoriasis.
- This study investigates a rare case of guttate psoriasis following streptococcal anitis.
Observation:
- A 4-year-old boy presented with perianal erythema and guttate psoriasis lesions.
- Group A beta-haemolytic streptococcus was identified in the perianal region.
- The patient received antibiotic treatment and topical corticosteroids.
Findings:
- Complete resolution of guttate psoriasis and anal symptoms occurred within one month.
- No relapse was observed during a 6-month follow-up period.
- This case supports a link between non-pharyngeal streptococcal infections and guttate psoriasis.
Implications:
- Highlights the importance of examining the perianal region in children with guttate psoriasis.
- Reinforces the association between streptococcal infections and guttate psoriasis.
- Suggests considering non-pharyngeal streptococcal sources in pediatric guttate psoriasis cases.
Background:
The link between guttate psoriasis and streptococcal infection is acknowledged. This form of psoriasis generally follows pharyngitis, but a small number of cases have been described as being triggered by a streptococcal infection other than in the throat. We report the case of a child with streptococcal anitis followed by guttate psoriasis.
Case Report:
A 4-year-old boy presented painful perianal erythema present for two weeks with diffuse lesions of guttate psoriasis present since the second week. Group A beta-haemolytic streptococcus was found during bacterial examination of the anal region. After one month of antibiotic treatment with josamycin combined with daily application of desonide 0.05% topical cream, all symptoms subsided without relapse in the ensuing 6 months.
Discussion:
This case demonstrates the need for careful clinical examination, both of the nose and throat but also of the perianal region, in children consulting for guttate psoriasis. It also demonstrates the strong link between guttate psoriasis and streptococcal infections in certain patients.
