A 10-year-old boy presented with a 5-year history of an intractably pruritic, recalcitrant psoriasiform plaque in a broad vertical band on the left buttock, with histologic as well as clinical features suggestive of an inflammatory linear verrucous epidermal nevus. This lesion was completely superimposed upon a congenital Becker nevus. We postulate that the restricted distribution and persistence of the psoriasiform plaque reflected an inflammatory response limited to the aberrant clone of cells composing the Becker nevus, a manifestation of cutaneous mosaicism that could be characterized as an "inflammatory Becker nevus."
一名10岁男孩左侧臀部有一广泛垂直条带分布的顽固性瘙痒、难治性银屑病样斑块,病史5年,组织学及临床特征提示为炎症性线状疣状表皮痣。该病变完全叠加于先天性贝克痣之上。我们推测,银屑病样斑块的局限性分布和持续存在反映了一种炎症反应,该反应局限于构成贝克痣的异常细胞克隆,这是一种皮肤镶嵌现象的表现,可被描述为“炎症性贝克痣”。
