Lichen planus (LP) is a common idiopathic inflammatory disorder that affects the flexor aspect of the wrists, the legs, and the oral and genital mucosa. Depending upon the site of involvement, LP can be divided into mucosal, nail, scalp, or palmoplantar types. Palmoplantar LP can pose a diagnostic problem to the clinician as it resembles common dermatoses like psoriasis, verruca, corn, calluses, lichenoid drug eruption, and papular syphilide of secondary syphilis. In this case report, we describe a 4-year-old male child who presented with highly pruritic erythematous to violaceous hyperkeratotic papules and plaques on his palms and soles. Typical LP papules were noted on the upper back. Histopathology of the papular lesion showed features of LP. Dermatoscopy of a papule from the back showed the characteristic Wickham striae. We report this rare involvement of palm and soles in a case of childhood LP.
扁平苔藓（LP）是一种常见的特发性炎症性疾病，可累及手腕屈侧、腿部以及口腔和生殖器黏膜。根据受累部位，LP可分为黏膜型、甲部型、头皮型或掌跖型。掌跖型LP可能给临床医生带来诊断难题，因为它类似于常见的皮肤病，如银屑病、疣、鸡眼、胼胝、苔藓样药疹和二期梅毒的丘疹性梅毒疹。在本病例报告中，我们描述了一名4岁男童，其手掌和脚底出现高度瘙痒的红斑至紫罗兰色角化过度丘疹和斑块。上背部可见典型的LP丘疹。丘疹病变的组织病理学显示为LP特征。背部丘疹的皮肤镜检查显示有特征性的威克姆纹。我们报告了这例儿童LP罕见的手掌和脚底受累病例。
