BACKGROUND: In this study, the molecular mechanisms underlying malignant transformation from oral lichen planus (OLP) to oral squamous cell carcinoma (OSCC) were examined. METHODS: High-throughput sequencing of long noncoding RNAs (lncRNAs) and mRNAs of normal subjects and patients with OLP and OSCC was conducted. RNA-seq reads were mapped, lncRNA and mRNA transcripts were assembled, and expression levels were estimated. The targets of lncRNAs were predicted. Finally, Gene Ontology (GO) and pathway enrichment analyses of differentially expressed genes (DEGs) and lncRNA targets were performed...

Oral lichen planus is a relatively common T-cell mediated inflammatory disease with potential malignant transformation. It may present itself with pain and oral lesions such as ulcers and Wickham’s striae. Treatment includes topical corticosteroids, preferably Clobetasol, immunosuppressive drugs and retinoids. Hyaluronic acid and aloe vera have been proven to be successful. If topical treatment fails, systemic therapy with corticosteroids may be needed. Because of the potential malignant transformation periodic follow-up is mandatory...

Lichenoid keratosis (LK), also known as benign lichenoid keratosis or lichen planus-like keratosis, is a solitary, pink to red-brown scaly plaque representing a host immunological response to a variety of precursor lesions. LK is often misdiagnosed as a dermatological malignancy owing to its clinical resemblance to basal cell carcinoma (BCC) or Bowen disease. We performed a retrospective analysis of the pathology records of a series of LK lesions with reference to the demographic features and accuracy of clinical diagnosis...

Hybrid lead halide perovskites have emerged as high-performance photovoltaic materials with their extraordinary optoelectronic properties. In particular, the remarkable device efficiency is strongly influenced by the perovskite crystallinity and the film morphology. Here, we investigate the perovskites crystallisation kinetics and growth mechanism in real time from liquid precursor continually to the final uniform film. We utilize some advanced in situ characterisation techniques including synchrotron-based grazing incident X-ray diffraction to observe crystal structure and chemical transition of perovskites...

Rapid global deforestation has forced many of the world's primates to live in fragmented habitats, making the understanding of their behavioral responses to degraded and fragmented habitats a key challenge for their future protection and management. The black-and-white snub-nosed monkey (Rhinopithecus bieti) is an endangered species endemic to southwest China. The forest habitat ranges from near-continuous to fragmented. In this study, we investigated the activity budget and diet of a R. bieti population that live in an isolated and degraded habitat patch at Mt...

Lichen planus pigmentosus is a pigmentary disorder of unknown etiology, with diffuse hyperpigmentation of sun-exposed areas, more commonly seen in some ethnic and racial groups. We report an unusual case of lichen planus pigmentosus in a 40-year-old man with Fizpatrick type III skin that was present in a blaschkoid distribution on the trunk, a distribution that has been rarely reported. This unique presentation of lichen planus pigmentosus may contribute to better understanding of the etiology, as the blaschkoid distribution may reflect underlying cutaneous mosaicism that renders those cells more susceptible to an insult that results in lichen planus pigmentosus...

Lichen sclerosus (LS) is a benign, chronic, inflammatory skin disease with a predilection for the anogenital region in women. Although males can also be affected, the ratio of female to male incidence has been reported to be as high as 6-10:1 and possesses a bimodal age distribution of pre-pubertal girls and postmenopausal women [1, 2]. Affected skin usually demonstrates polygonal papules that coalesce into porcelain white plaques and can be associated with edema, telangiectasias, and comedo-like plug formation [3]...

Lichen sclerosus et atrophicus (LSA) is a chronic inflammatory dermatosis, characterized by shiny, atrophic, hypochromic papules with a predilection for the genital and perineal skin. Extragenital involvement may occur, but is rare in the isolated form. LSA more commonly affects prepubertal and postmenopausal women. We describe an unusual case of isolated extragenital LSA, restricted to the wrists and mimicking lichen planus.

OBJECTIVES: Lichen planus has been recently associated with an increased risk of cardiovascular diseases (CVDs). The oral manifestations can be divided into white hyperkeratotic lesions (WL) and atrophic erosive lesions (RL). The aim of this report was to compare the presence of CVDs between patients affected by WL or RL, to test the hypothesis that RL are associated with an increased incidence of CVDs. SUBJECTS AND METHODS: Patients were analysed through a complete collection of all the risk factors for CVDs...

BACKGROUND: Chronic cutaneous lupus erythematosus (CCLE) often affects the scalp resulting in scarring alopecia. While histopathologic findings of CCLE have been well described, there is little written on the morphologic changes to the hair follicles in this condition. OBJECTIVE: We aim to determine the histopathologic findings of hair follicles in CCLE of the scalp. METHODS: We conducted a retrospective study of 33 transversely sectioned skin biopsy specimens of CCLE of the scalp at the Skin Pathology Laboratory at Boston University between April 2005 and March 2015...

Mesenchymal stem cells (MSCs) have potent immunomodulatory functions and are a promising therapy for immune-mediated inflammatory disorders. We previously demonstrated the efficacy of fresh, autologous, adipose-derived MSCs (ASCs) to treat feline chronic gingivostomatitis (FCGS), a chronic oral mucosal inflammatory disease similar to human oral lichen planus. Here, we investigate the use of fresh allogeneic ASCs for treatment of FCGS in seven cats. Radiolabeled ASCs were also tracked systemically. Each cat received two intravenous injections of 20 million ASCs, 1 month apart...
