Lichen planus pemphigoides (LPP) is a rare blistering disease with features of both lichen planus and bullous pemphigoid. LPP typically appears on the extremities and occasionally involves the oral mucosa. Herein, we describe a case of LPP of the vulva of an 80-year-old woman, an uncommon location for this disease process. This clinical scenario can be confused with a number of similarly appear...

Lichen myxedematosus is a cutaneous mucinosis of idiopathic origin. According to Rongioletti’s classification, 2006, lichen myxedematosus is classified into three forms. The scleromyxedema or lichen myxedematosus sclerodermiform and generalized is a form of lichen myxedematosus characterized by numerous papules and areas of cutaneous hardening due to the deposition of mucin in association with ...

lichen planus (lp) is a chronic mucocutaneous disease widely recognized in adults, but uncommon in children. the purpose of this paper is to report two cases of lp in children. the diagnosis was made based on clinical and histopathological findings. the treatment consisted of antifungal and multivitamin therapy. regression of lesions was observed. the patients are still under follow up. althoug...

Lichens are known to be bioaccumulators of atmospheric pollutants and are abundant in the Canadian arctic. Mining in this region may negatively impact the tundra communities and these impacts may be detected by increased accumulation of heavy metals, greenhouse gas constituents, and organic compounds in lichen tissue. The effect of sampling direction and distance from a diamond mine on bioaccum...

OBJECTIVES The vulva is the primary site affected in lichen sclerosus, a chronic dermatosis in women that is histologically characterized by a zone of collagen remodeling in the superior dermis. The normal physiological properties of the vulva depend on the assembly of collagen types I (COLI), III (COLIII) and V (COLV), which form heterotypic fibers, and extracellular matrix protein interaction...

BACKGROUND The aims of this study were to assess the prevalence of hepatitis C virus (HCV) infection in Japanese patients with oral lichen planus and identify the impact of amino acid (aa) substitutions in the HCV core region and IFN-sensitivity-determining region (ISDR) of nonstructural protein 5A (NS5A) associated with lichen planus. METHODS In this retrospective study, 59 patients (group 1...

discussion the disappearance of olp might be due to immunosuppressive therapy following liver transplantation. further observations and studies are necessary to clarify the relationship between olp and pbc. case presentation we describe a case of oral lichen planus (olp) accompanied with pbc that resolved following liver transplantation 14 years later. this patient received immunosuppressive dr...

BACKGROUND An association between HCV infection and lichen planus is uncertain because the prevalence of HCV infection in patients with lichen planus varies considerably from one geographic area to another. The purpose of this study was to determine the frequency of anti-HCV antibodies and its association with various clinical types of lichen planus in Mekkah, Saudi Arabia. METHODS A total of...

Fungi comprehend a heterogeneous group of heterotrophic microorganisms that act as saprobes or parasites or, less frequently, as symbionts living in association with other organisms. They are cosmopolitan and important components of ecosystems. Considering the small number of Brazilian papers on the filamentous mycota in marine environments, and the need to improve knowledge of the diversity of...
