The aim of this study was to investigate the antifungal effects and molecular changes caused by Usnea longissima Ach. extracts against Fusarium greaminearum. In agar well diffusion assay, zone inhibition increased as concentration in both methanol acetone (1, 10, 20 50 mg/ml). terms bioactivities, 1 mg/ml active, while other concentrations were very active. At level, extract analyzed qPCR with ...

Lichen planus is a T-cell mediated autoimmune disorder affecting the skin and mucous membranes. Ulcerating lichen planus is uncommon mostly on oral and genital mucosa but not skin.

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.

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...
