Diagnostic
Guttate Psoriasis
Dermoscopy of guttate psoriasis shows uniformly distributed red dotted vessels, diffuse white-grey scales, and a background that can range from bright red to dull red or pink. These features are diagnostic across all skin types and help in distinguishing guttate psoriasis from other dermatological conditions.
Diagnosis and Differential Diagnosis
Guttate psoriasis is typically diagnosed based on clinical examination and dermoscopic findings. A skin biopsy may be performed for confirmation. Differential diagnosis includes conditions such as pityriasis rosea, pityriasis lichenoides chronica, and secondary syphilis, among others.
