BACKGROUND Sarcoptes scabiei can be visualized with different imaging tools. Optical coherence tomography (OCT) may have the potential to describe the changes in skin morphology due to scabies infestation and visualize the parasite. METHODS Five patients from the Departments of Dermatology, Augsburg, Germany, and Roskilde, Denmark, were OCT scanned(More)
BACKGROUND Photodynamic therapy with methyl aminolaevulinate (MAL-PDT) is a widely used non-invasive treatment modality for non-melanoma skin cancer (NMSC). The outcome of MAL-PDT is usually primarily evaluated clinically. Optical coherence tomography (OCT) is a non-invasive imaging technology based on interferiometry. OCT has been proven to provide high(More)
Vascular malformations commonly occur in the facial region, and can be associated with significant stigma and embarrassment. Studies have shown that even recommended light-based treatments do not always result in complete clearance. This indicates the need for more accurate pre-treatment assessment of vessel morphology to optimize treatment settings and(More)
Since its introduction in dermatology in the late 1990s optical coherence tomography (OCT) has been used to study many skin diseases, in particular non-melanoma skin cancer and it s precursors. Special attention has been paid to superficial basal cell carcinoma (BCC), and a number of smaller observational studies have been published. The diagnostic criteria(More)
Optical coherence tomography (OCT) represents a non-invasive imaging technology, which may be applied to the diagnosis of non-melanoma skin cancer and which has recently been shown to improve the diagnostic accuracy of basal cell carcinoma. Technical developments of OCT continue to expand the applicability of OCT for different neoplastic and inflammatory(More)
BACKGROUND Brimonidine is a selective α2 adrenergic receptor agonist with potent vasoconstrictive activity topically used for treatment of facial flushing and erythema caused by rosacea. Direct evidence for the in vivo morphology changes in skin vessels induced by topical application of brimonidine is limited. Dynamic optical coherence tomography is a novel(More)
INTRODUCTION Skin cancer follow-up is a substantial burden to outpatient clinics. Few studies have investigated patients' views on skin cancer follow-up and cutaneous melanoma. The objective was to investigate patients' perceived benefits and the impact of follow-up. MATERIAL AND METHODS This study included an open sample of patients attending routine(More)
Importance Vasculopathy characterized by functional and structural abnormalities of the microcirculation plays an important role in systemic sclerosis and dermatomyositis. Although there are several advantages in using capillaroscopy, the method does not offer insight on the skin architecture, flow status, or morphology of the deeper dermal vessels. Dynamic(More)
BACKGROUND Optical coherence tomography (OCT) is a non-invasive optical imaging technique providing high-resolution images. OCT may be useful as a monitoring tool during treatment of actinic keratoses (AK) and skin cancer. OBJECTIVE To examine and describe how OCT skin morphology changes when the tissue is exposed to the effects of cryotherapy. METHODS(More)
PURPOSE To explore the application of optical coherence tomography (OCT) imaging of basal cell carcinomas (BCC) and actinic keratosis (AK) before, during and after imiquimod treatment and the ability of OCT to predict treatment outcome. METHODS The study subjects were 20 patients with biopsy-verified BCC (9) or AK (11). Patients were OCT-scanned before,(More)
