Background Basal cell carcinoma (BCC) is the most common skin cancer in general population. Treatments vary from Mohs surgery to topical therapy, depending on subtype. Dermoscopy, reflectance confocal microscopy (RCM) and optical coherence tomography (OCT) have gained a foothold daily clinical practice optimize diagnosis subtype-oriented treatment. The new technique of line-field OCT (LC-OCT) allows imaging at high resolution depth, but its use has not yet been investigated larger studies....

Abstract Background The treatment of keratinocyte cancers (KC) strictly depends on their differentiation and invasiveness. Non‐invasive diagnostic techniques can support the diagnosis in real time, avoiding unnecessary biopsies. This study aimed to preliminarily define main imaging criteria histological correlations actinic keratosis (AK), Bowen’s disease (BD) squamous cell carcinoma (SCC) using novel device line‐field confocal optical coherence tomography (LC‐OCT). Methods Dermoscopy LC‐OCT...

Demodex spp. mites are the most complex resident of human skin microbiome. Although they considered commensals, can be pathophysiologically relevant in inflammatory diseases like rosacea. Until now, there is no culture system available for these except using live vertebrate hosts.Our aim was to establish an ex vivo and characterize sebogenesis-dependent mite density.Demodex were cultivated pilosebaceous units explants, called organotypic explant (hOSEC). Furthermore, different...
