PURPOSE Using pathological examination we evaluated the involvement of lichen sclerosus in urethral strictures in men. MATERIALS AND METHODS We performed an observational, descriptive, retrospective study of patients treated for genital lichen sclerosus who had at least 1 biopsy positive for lichen sclerosus. Study exclusion criteria were malignant penile lesions, incomplete data on personal ...

Lichen sclerosus, lichen planus, and lichen simplex chronicus are three of the most common non-neoplastic epithelial disorders of the vulva. Lichen sclerosus is characterized by intense vulvar itching and can affect men and women of all ages, but it manifests most commonly in postmenopausal women. Patients with lichen sclerosus have an increased risk of developing squamous cell carcinoma, and t...

oral lichen planus is a chronic inflammatory immune-mediated disease. icam-1 and vcam-1 are vascular adhesion molecules that their receptors are located on endothelial cells and leukocytes. the aim of this study is the immunohistochemical evaluation of vcam1 and icam1 in oral lichen planus and to compare these two markers with normal mucosa for evaluation of angiogenesis. this descriptive-analy...

B. was treated with different concentrations methanolic aqueous extracts D. P. lichens. Total activities that showed the best growth lichen application control Methanolic extract allelopathic plants ...

Lichen planus is a chronic papulosquamous dermatoses in which both skin and mucosae are involved. There are various morphological forms of lichen planus. Hypertrophic lichen planus is one of the rare clinical variants. Herein, we report a very unusual presentation of hypertrophic lichen planus. A similar presentation has not been reported in literature yet, to the best of our knowledge.

Lichen planus is an inflammatory dermatosis with a prevalence of approximately 1%. Recent meta-analyses show that patients with hepatitis C virus have a 2.5- to 4.5-fold increased risk of developing lichen planus. Lichen planus has also followed vaccinations and has specifically been attributed to the hepatitis B vaccine, the influenza vaccine, and the tetanus-diphtheria-acellular pertussis vac...

•Lichen sclerosus in females primarily involves the hairless anogenital skin.•Skin tissue outside this area is constitutionally not at risk for lichen sclerosus.•Transplantation into the vulvar field may turn skin susceptible to lichen sclerosus.•Tissue inherent positional information might affect lichen sclerosus susceptibility.

Erosive lichen planus is an uncommon variant of lichen planus. Chronic erosions of the soles, accompanied by intense and disabling pain, are some of its most characteristic manifestations. We present the case of a woman who developed oral and plantar erosive lichen planus associated with lichen planus pigmentosus and ungueal lichen planus that were diagnosed after several years. The patient fai...

BACKGROUND & AIMS There is a close relationship between hepatitis C virus (HCV) infection and lichen planus, a chronic inflammatory mucocutaneous disease. We performed a genome-wide association study (GWAS) to identify genetic variants associated with HCV-related lichen planus. METHODS We conducted a GWAS of 261 patients with HCV infection treated at a tertiary medical center in Japan from Oc...
