ReferencesGuttate psoriasis は、喉や肛門周囲の感染症などの連鎖球菌感染症によって引き起こされることが多い、乾癬の特殊な形態です。成人よりも子供や十代の若者に多くみられます。この症状のある人には、小さな涙滴型の病変が複数出現しますが、通常は局所用クリームや光療法で改善します。
Guttate psoriasis is a distinct variant of psoriasis that is classically triggered by streptococcal infection (pharyngitis or perianal) and is more common in children and adolescents than adults. Patients present with several, small “drop-like” lesions that respond well to topical and phototherapies.

Guttate psoriasis は、子供の 0.5～2% が罹患する一般的な疾患です。通常、主に体幹や四肢に、小さく点在した涙型の鱗屑を伴う赤い隆起や斑点が多数、突然出現します。最近の溶連菌感染症に関連していることもあります。瘢痕を残さずに 3～4 か月以内に自然に治ることもありますが、再発したり持続したりし、症例の 40～50% で慢性尋常性乾癬に移行する場合もあります。自然に消えることもあるため、外観やかゆみ以外の症状がなければ必ずしも治療は必要ありません。
Guttate psoriasis is common and affects 0.5–2% of individuals in the paediatric age group. Guttate psoriasis typically presents with an abrupt onset of numerous, small, scattered, tear-drop-shaped, scaly, erythematous, pruritic papules and plaques. Sites of predilection include the trunk and proximal extremities. There may be a history of preceding streptococcal infection. Koebner phenomenon is characteristic. Guttate psoriasis may spontaneously remit within 3–4 months with no residual scarring, may intermittently recur and, in 40–50% of cases, may persist and progress to chronic plaque psoriasis. Given the possibility for spontaneous remission within several months, active treatment may not be necessary except for cosmetic purposes or because of pruritus. On the other hand, given the high rates of persistence of guttate psoriasis and progression to chronic plaque psoriasis, some authors suggest active treatment of this condition.
