We report on spectral reflectance measurements of basaltic lava flows on Tenerife Island, Spain. Lava flow surfaces of different ages, surface roughness and elevations were systematically measured using a field spectroradiometer operating in the range of 350–2500 nm. Surface roughness, oxidation and lichen coverage were documented at each measured site. Spectral properties vary with age and mor...

Lichen nitidus is an uncommon idiopathic chronic dermatosis characterized by minute, flesh-colored or hypopigmented, shiny papules commonly occurring on the abdomen, chest, genitalia, and extremities. The disorder is most often localized but, rarely, can become extensive or generalized. The occurrence of lichen nitidus during infancy is extremely rare. A perusal of the English literature reveal...

Androgenetic alopecia is often treated by follicular unit transplantation, a technique that involves minimal risk of hair loss because of the more resistant nature of the donor area. Lichen planopilaris is a cicatricial alopecia that causes permanent destruction of hair follicles. We report two cases of post-transplantation lesions compatible with lichen planopilaris in both recipient and donor...

Lichen planopilaris is a disease that appears with lymphocytic cicatricial alopecia. It is considered a follicular variant of lichen planus. The examination of affected areas shows alopecia with perifollicular erythema and scaling, revealing a predilection for hair follicles. The involvement of children is uncommon, with few reports in this population in the literature. This study presents a cl...

INTRODUCTION Corticosteroids are the mainstay for treatment of oral lichen planus (OLP) and have their own side effects. The aim of this study was to compare the therapeutic effects of aloe vera (AV) mouthwash with triamcinolone acetonide 0.1% (TA) on OLP. METHODS A total of 46 patients with OLP were enrolled in this study. The patients were randomly divided into 2 groups. Each group was trea...
