BACKGROUND Oral lichen planus (OLP) is a common chronic inflammatory mucocutaneous disease. Clinical diagnosis of OLP requires clinical work-up and histologic examination to rule out possible dysplasia and carcinoma. It is possible that oral mucosal viral infections including HPV infection may have a causative role in OLP pathogenesis. The aim of this study was to examine the coincidence of hum...

Lichen sclerosus is a chronic inflammatory disease that can progress to malignancy. The literature indicates an association with anogenital squamous cell carcinoma and verrucous carcinoma. Two pathogenic pathways, differentiated vulvar and penile intraepithelial neoplasias, which have recently been described in relation to squamous cell carcinoma, are both highly associated with genital lichen ...

Frontal fibrosing alopecia is a variant of lichen planopilaris with marginal progressive hair loss on the scalp, eyebrows and axillae. We report a case of frontal fibrosing alopecia and lichen planus pigmentosus in a postmenopausal woman, that started with alopecia on the eyebrows and then on the frontoparietal region, with periocular and cervical hyperpigmentation of difficult management. The ...

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...

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...
