A preceding streptococcal infxn is seen in more than half of pts who develop acute guttate psoriasis. This pt had raised anti-streptolysin-O and anti-DNase-B titers, confirming recent strep infxn. Antibodies to coxsackievirus and Rocky Mountain spotted fever were negative. He was treated successfully w/ triamcinolone and topical calcipotriol and had no relapse after 1 yr.
