Abstract
Linear lichen planus pigmentosus is a rare subtype of lichen planus pigmentosus that follows Blaschko's lines, leaving long-standing residual atrophy and pigmentation, especially in dark-skinned populations. Conventional treatments have several limitations regarding the alleviation of pigmentation and atrophy. We report two cases of Korean women with linear lichen planus pigmentosus on their faces who were successfully treated with fractional lasers and intralesional injection of polydeoxyribonucleotide.

Abstract
Linear hyperpigmentation is an unusual anatomical configuration in clinical dermatology. Owing to its rarity, consensus on the most effective method of classification is lacking. While linear hyperpigmentation generally follows Blaschko's lines, this is not universal. Clinical findings such as adherence to Blaschko's lines, associated morphological findings (including other cutaneous lesions), and systemic manifestations can be used to further characterize and diagnose variants of the disorder. Early detection of any underlying disease is vital, especially in cases with effective management, because the disorder may make it difficult to manage hyperpigmentation. Herein, we introduce a logical clinical diagnostic approach that represents a useful tool for dermatologists to efficiently evaluate patients presenting with linear hyperpigmentation. A simplified systematic and evidence-based approach is useful for this clinical condition owing to the heterogeneous causes and lack of specific diagnostic tools.

Abstract
Lichen planus pigmentosus (LPP) is a rare disorder affecting primarily the people with ethnic skin. It results in hyperpigmentation of sun-exposed sites along with the involvement of flexures. In accordance with clinical patterns, different variants such as diffuse, blotchy, reticulate, and perifollicular have been described. Rare variants such as flexural (inversus), mucosal, linear, and zosteriform have been reported scarcely. Inversus LPP refers to the involvement of major flexures such as inframammary area, axillae, and groins in the absence of involvement of photo-exposed sites. We present an unusual case presenting with coexisting linear and inversus variants of LPP.

Abstract
Lichen planus pigmentosus (LPP) is chronic pigmentary disorder that shows diffuse or reticulated hyperpigmented, dark brown macules on the sun-exposed areas such as the face, neck and other flexural folds. Clinically, it is different from classical lichen planus because LPP has a longer clinical course and it manifests with dark brown macules. In case of LPP, involvement of the scalp, nail or mucosal area is rare. The histopathological findings of the lesions show an atrophic epidermis, the presence of melanophages and a vacuolar alteration of the basal cell layer with a sparse lymphohistiocytic lichenoid infiltration. Although there have been a few reports of LPP, there have only 3 cases of linear LPP along the lines of Blaschko in the Korean dermatologic literature. Our patient had lesions on the neck and chin with a linear pattern. In this report, we describe a very rare case of LPP with a linear distribution related to Blaschko's lines on the neck and chin areas.

Abstract
Linear lichen planus (LLP) is a very rare form of lichen planus (LP) characterized by a linear distribution of the lichenoid lesions. It usually follows the lines of Blaschko with unilateral involvement. We report such a case of LLP. A 50-year-old man presented with slightly pruritic, linear, violaceous, papular lesions on the right side of his jaw. A biopsy specimen demonstrated the typical histology of LP. Based on the clinical and pathological findings, the diagnosis was LLP.
