Explanation
Guttate psoriasis is characterized by numerous small (0.5-1.5 cm) drop-shaped papules scattered over the trunk and proximal limbs, typically triggered by group A streptococcal infection in young patients. The term guttate derives from the Latin 'gutta' meaning drop. It can be a presenting form or an exacerbation of existing psoriasis, and while most cases resolve spontaneously, a proportion progress to chronic plaque psoriasis. HIV infection can trigger or worsen psoriasis.
