Oral lichen planus which is one of the most common oral mucosal diseases in adults, it has been rarely described in children. There are very reports in the literature regarding oral lichen planus in children, here we report a case of intraoral lesions of lichen planus. Lichen planus should be considered in the differential diagnosis of hyperkeratotic or erosive lesions of the oral mucosa in chi...

INTRODUCTION Up to 30% of squamous cell carcinomas of the penis arise from a lichen sclerosus, but very few reports in which lichen planus was the preexisting lesion have been published. We report a male with verrucous carcinoma of penis that developed in an area of lichen planus. CLINICAL CASE A 53-year-old male presented with an exophytic tumor on the glans penis that had been present for a...

Aim of the present investigation was to analyse the possible malignant transformation of oral lichen planus to carcinoma, especially in the atrophic erosive forms and those displaying plaques involving the top of the tongue. A review has been made of the literature, from 1986 to the present day. This search outlines the relationship between oral lichen planus, hepatitis C virus infection, Epste...

We speculate that heterotrophic and/or silica-rich eukaryotic microorganisms maybe an important part of the lichen symbiosis. None of the very few studies of heterotrophic protists associated with lichens have considered the possibility that they may be of functional significance in the lichen symbiosis. Here we start to develop, currently speculative, theoretical ideas about their potential si...

Lichens are symbiotic organisms of fungi and algae or cyanobacteria. Lichen-forming fungi synthesize a great variety of secondary metabolites, many of which are unique. Developments in analytical techniques and experimental methods have resulted in the identification of about 1050 lichen substances (including those found in cultures). In addition to their role in lichen chemotaxonomy and system...

INTRODUCTION Lichen planus is a chronic, inflammatory, autoimmune skin condition that can affect the skin, mucosal surfaces, and nails. Mucosal lichen planus might occur in conjunction with or without cutaneous involvement. Current treatment options include both topical and systemic medications. Tacrolimus (FK-506 or fujimycin) is a macrolide immunosuppressant that inhibits calcineurin. Topical...

Lichen planus is a papulosquamous disorder of skin. Genital lichen planus is self limiting disease that resolves without any consequences. Although Lichen planus may coexist with lichen sclerosus et atrophicus, such association in genitalia is not reported so far. We report a case of a forty years old man, presented with a papulosquamous lesion over the prepuce four years back and then he subse...

We describe a fifty-six-year old, Afro-descendent female patient showing dystrophy of her twenty nails and hyperchromic, asymptomatic macule on her face. Histopathological examination of the macule showed vacuolization of the basal layer, melanophages in the superficial dermis and lymphoplasmocytic inflammatory infiltrate. Nail biopsy revealed orthokeratotic hyperkeratosis and lichenoid inflamm...

A number of genetic, congenital and acquired dermatoses have been known to follow Blaschko's lines. A common disorder like lichen planus can very rarely present with pruritic lesions in atypical patterns such as unilateral distribution, painful eruptions and along Blaschko's lines. Various triggering factors varying from viral infections and vaccinations to trauma have been implicated in lichen...

Background: Lichenoid disorders are often difficult to diagnose clinically. Dermoscopy can act as an alternative technique to skin biopsy for diagnosis of various lichenoid dermatoses. Study aim: To study the correlation of dermoscopic with histopathological findings in various lichenoid dermatoses Methods: Fifty patients with clinical picture of lichenoid dermatoses were examined first under t...
