This patient’s presentation is indicative of guttate psoriasis, a skin disorder characterized by the acute onset of numerous, small, discrete papules and plaques on the trunk and extremities that are covered with a fine scale. The condition is associated with a preceding streptococcal infection, often streptococcal pharyngitis, in up to 97% of cases.
