BACKGROUND Verrucous carcinoma of the vulva is extremely rare. It is a slow growing, low malignant variant of a squamous cell carcinoma with a cauliflower appearance. Women with lichen planus have an increased risk of developing vulval cancer. CASE PRESENTATION A 79-year-old woman consulted for vulval itching. On clinical examination, a 3-cm large verrucous clitoral cancer in an area of liche...

Lupus erythematosus, especially the discoid form, and lichen planopilaris may be associated and can occur in different topographies (coexistence) or in the same lesion (lupus eythematosus/lichen planus overlap syndrome). Frontal fibrosing alopecia is considered a variant form of lichen Received: October 24, 2016 Accepted: October 27, 2016 Published online: November 12, 2016 Leandro Noriega Derm...

ABSTRACT The relationship between chronic hepatitis C virus infection (HCV) and oral lichen planus (OLP) is a current topic in the field of oral medicine. Many studies of this association have been made over time. The geographic variation of the hepatitis C prevalence proved to be an important factor influencing the statistical results of the studies analyzing the association of the oral plan l...

Lichen planopilaris (LPP) is also known as lichen follicularis or follicular lichen planus. LPP is a cutaneous disorder selectively involving hair follicles with a lymphocytic inflammatory process that eventually destroys the follicles 1. LPP is more common in women (60% to 90% of the cases) than men 2. LPP is a disease of unknown etiology whose pathogenesis is poorly understood despite a suspe...

Lichen planus and vitiligo are common skin disorders. Colocalization which is rarely reported may consider the koebner phenomenon related to the photo damage causing initiation of lichen planus over vitiliginous skin. We report a 37-year-old mother and her 23-year-old daughter, both farmers and known cases of vitiligo with subsequent gradual onset of pruritic skin lesions of lichen planus start...

A 20-year capture-recapture study of alpine grasshoppers spanned three distinct sequences of abundance, featuring in turn dis-equilibrium, equilibrium and secondary cyclic equilibrium. This succession of population patterns in the most abundant species, Paprides nitidus, retained high stability between generations. It arose via superimposed life-cycle pathways and adaptive responses between gra...

Association of lichen planus and cutaneous malignancies is rare. Reports of neoplastic changes are mostly related to buccal chronic erosive lichen planus. We report herein a 29-year-old man who developed squamous cell carcinoma on previous lesions of chronic hypertrophic lichen planus of lower legs. Careful follow up of patients with chronic lichen planus and biopsy sampling of uncommon lesions...

A 43-year-old man with generalized lichen planus demonstrated serum antibodies against autologous lesional skin. Indirect immunofluorescence using serum and papular lesional skin revealed a lichen planus specific antigen found only in the granular layer. The specific tissue antigen was not detected in normal skin from this patient, in normal skin from patients with skin disorders other than lic...
