CASES 4A AND 4B: Guttate Psoriasis
June 01, 2003
By Joe Monroe, PA-C [1]
4A:Small, slightly pruritic, salmon pink papules with thick white scale have arisen over the past 5
days on the trunk and arms of a 24-year-old man. The patient has a history of very mild psoriasis
vulgaris of the elbows, knees, and scalp; he denies streptococcal pharyngitis or other recent
infections. Guttate psoriasis is diagnosed.

4B:The abrupt onset of a generalized exanthem of multiple small, scaly papules sends a 19-year-old
woman for medical evaluation. The patient had a sore throat 2 weeks earlier. She uses no
medications and has no allergies. Scattered, discrete, 0.2- to 1.0-cm, salmon pink, scaling papules
involve most of the body symmetrically; the palms and soles are spared. All laboratory test results
are normal except for an elevated antistreptolysin-O titer. The clinical picture and history suggest
guttate psoriasis. (Case and photograph courtesy of Drs Tausif Zar and Claudia McClintock.) What
strategies would you pursue in these patients?
A REVIEW OF THE OPTIONS Guttate psoriasis is characterized by teardrop-size pink papules that
often develop in response to a streptococcal or other upper respiratory tract infection. The lesions
are much smaller than those of psoriasis vulgaris; however, this usually shortlived condition can
evolve into chronic psoriatic disease. Generally, guttate psoriasis clears quickly; when lesions are
widespread, UV-B therapy may be recommended to accelerate clearing. Consider antibiotic therapy
when the patient's throat culture is positive or when episodes of guttate psoriasis recur. Penicillin,
cephalosporin, erythromycin, or rifampin can be used to eradicate group A β -hemolytic streptococci
and, in turn, help treat guttate psoriasis. CASE 4A:
APPROACH AND OUTCOME UV-B therapy successfully cleared the guttate psoriasis in this
24-year-old man. CASE 4B:
APPROACH AND OUTCOME No treatment was offered; the patient recovered spontaneously in 1
month. There were no residual signs of papules; a second antistreptolysin- O titer indicated no
infection.
