저용량 메토트렉세이트와 308-nm 자외선레이저 치료로 성공적으로 호전된 가성림프종과 유사하였던 림프종모양구진증 2예

Lymphomatoid papulosis (LyP) is a CD30+ Iymphoproliferative disorder characterized by chrome papulonodular eruptions. Highly potent topical steroids and phototherapy are the first-line modalities, and low-dose methotrexate (MTX) combined with folic acid is known to be safe and efficient for the treatment of LyP. However, there are concerns about whether whole-body phototherapy should be performed for limited lesions. Herein, we report the first case series of localized LyP mimicking pseudolymphoma successfully treated with low-dose MTX and 308 nm ultraviolet (UV) laser therapy. Clinicians should consider UV laser therapy as a novel treatment option because it has the advantage of selective treatment.
