Abstract

Lichen nitidus is a rare, chronic, papulosquamous disease that is characterized by minute, flesh-colored, shiny, multiple, dome-shaped papules. Variants of lichen nitidus are purpuric, keratodermic, vesicular and hemorrhagic, petechial, perforating, spinous follicular, linear and actinic types. The pathogenesis of lichen nitidus are unknown. The histopathologic findings in lichen nitidus are very characteristic and shown hyperplastic rete ridges in a 'ball and claw' configuration. Treatment especially is counseled in the presence of pruritus and for the cosmetic reasons. 15-year-old male patient applied to hospital with the complaints of lesions for 4 months and healing as brown coloring. It is diagnosed as lichen nitidus clinically and histopathologically. His lesions were localized atypically and healed leaving postinflammatory hyperpigmentation. As a treatment, topical corticosteroid pomade and oral antihistaminic tablet were began. Lesions gave good response to the treatment. We reported this case due to its rarity.

Liken nitidusun varyantları; purpurik, keratodermik, veziküler ve hemorajik, peteşial, perforan, spinöz foliküler, lineer ve aktinik tiplerdir. Liken nitidusun patogenezi bilinmemektedir. Histopatolojik bulguları oldukça tipik olup hiperplastik rete uçları pençe ve top benzeri görünüm göstermektedir. Tedavi kaşıntı varlığında ve kozmetik amaçla gerekmektedir. Genellikle sekelsiz veya hipopigmente maküller ile iyileşmektedir. Onbeş yaşında erkek hasta gövdesinde 4 aydır başlayan ve kahverengi leke bırakarak iyileşen lezyonlar nedeniyle başvurdu. Klinik ve histopatolojik olarak liken nitidus tanısı kondu. Olgumuzun lezyonları atipik yerleşim göstermekteydi ve postinflamatuvar hiperpigmentasyonla iyileşmekteydi.
