The etiology of pityriasis lichenoides is unknown. One of the accepted theories admits that PL is an inflammatory response to extrinsic antigens such as infectious agents, drugs and vaccines. In recent medical literature, only the MMR vaccine (Measles, Mumps and Rubella) was associated with the occurrence of this disease. We present a case of a male, 12 year old healthy patient who, five days after Influenza vaccination, developed erythematous papules on the trunk, abdomen and limbs, some with adherent crusts and associated systemic symptoms. This case report is notable for describing the first case of pityriasis lichenoides et varioliformis acuta associated with the vaccine against Influenza.
点滴状类银屑病的病因尚不清楚。一种被广泛接受的理论认为，点滴状类银屑病是对外源性抗原（如传染因子、药物和疫苗）的炎症反应。在最近的医学文献中，只有麻疹、腮腺炎和风疹联合疫苗（MMR疫苗）与该病的发生有关。我们报告一例12岁健康男性患者，在接种流感疫苗五天后，躯干、腹部和四肢出现红斑丘疹，部分伴有痂皮，并有相关全身症状。本病例报告的特别之处在于，它描述了首例与流感疫苗相关的急性痘疮样苔藓状糠疹病例。
