GUTTATE PSORIASIS: CLINICAL FEATURES, DIAGNOSIS, AND TREATMENT APPROACHES
Keywords:
guttate psoriasis, streptococcal infection, dermoscopy, differential diagnosis, narrowband UVB.Abstract
Guttate psoriasis is an acute variant of psoriasis characterized by a sudden “shower” of small, drop-like erythematous papules and thin plaques, most often distributed over the trunk and proximal limbs. It commonly affects children and young adults and is frequently triggered by infection—classically streptococcal pharyngitis—appearing about 1–2 weeks after an upper respiratory episode. Diagnosis is usually clinical, supported by dermoscopy and, when needed, biopsy. Because streptococcal infection can act as a trigger, evaluation may include throat culture and/or serologic markers (e.g., ASO, anti–DNase B) to document recent infection.
