In vivo differentiation of benign and malignant skin lesions is a fundamental issue in clinical dermatology. Malignant skin diseases are known to be accompanied by structural alterations. Conventional excisional biopsies and further histopathology are regarded as the reference standard for investigating these pathologies. Biopsies are invasive procedures and additionally may cause side effects. Therefore, research efforts are focused on the development of diagnostic techniques capable of providing in vivo information on the skin's structure. Optical coherence tomography (OCT) is a technical application, which allows the identification of microscopic patterns indicative for benign and malignant skin lesions. OCT is a promising noninvasive imaging technique for the micromorphology of the skin. So far, it's clinical application, as an additional diagnostic tool for malignant skin lesions has been studied in a limited extend. To evaluate the clinical usefulness of OCT, we conducted a prospective pilot study at the Department of Dermatology, Medical University of Vienna. The study is in cooperation with the Center of Biomedical Engineering and Physics at the Medical University of Vienna.
A total of 70 malignant skin lesions was evaluated during this prospective pilot study. Diagnoses based on OCT imaging as an additional diagnostic tool, were compared to those based on the clinical standard pathway at the Department of Dermatology, Medical University of Vienna. For the purpose of this study, the histopathological diagnosis was used as the reference diagnostic standard.
The major aims of this study is the investigation of the ability of ultrahigh resolution OCT to identify fine morphological characteristics associated with basal cell carcinoma, actinic keratosis, superficial squamous cell carcinoma, seborrheic keratosis, melanocytic nevi and melanoma.
- To correlate the morphologic features identified with ultrahigh resolution OCT with routine histopathology
- To investigate the clinical feasibility of ultrahigh resolution and spectroscopic OCT technology
- To assess the effectiveness of ultrahigh resolution and spectroscopic OCT imaging to diagnose various melanocytic and non-melanocytic skin tumors
- To compare the diagnostic capabilities of ultrahigh resolution OCT with standard non-invasive diagnostic procedures such as epiluminescence microscopy
