About the book
Skin cancer is the most common type of cancer in humans with worldwide incidence constantly on the rise. Coupled with an aging population, cutaneous neoplasm poses a serious problem in regard to the mortality, costs of healthcare systems, and patient's quality of life. Dermatoscopy is based on the phenomenon of Rayleigh scattering in the skin. It was developed as a non-invasive diagnostic modality and, even though initially aimed at early melanoma detection, it enhances the detectability of all types of skin cancer. Implementation of the polarized light into the dermatoscopic allowed the visualization of the new polarizing-dependent structures, and become a renaissance of the method, and was one of the pivotal factors responsible for the shift from metaphoric terminology to pattern analysis. Dermatoscopy is responsible for the decline in the costs of skin cancer care by the reduction of the number needed to treat and by facilitating earlier detection when minor surgery saves the patient from major procedures, expensive systemic treatment, and sequelae. Moreover, dermatoscopy is capable of predicting the selected data from the pathology report with dermatoscopy (Breslow thickness, melanoma subtype, BCC subtype, SCC grade, presence of ulceration, regression or prediction of positive sentinel lymph nodes) which may also serve as a secondary control for the report, and may be used to tailor the most beneficent treatment for each patient. This technique proved to be useful for pre-surgical or pre-radiotherapy estimating tumor margins, evaluating the effects/radicality of the therapy (surgery, radiotherapy, cryotherapy, electrocautery, laser ablation, systemic or topical treatment). With the introduction of videodermatoscopy and digital imaging in dermatoscopy, new possibilities emerged including digital follow-up of the suspected lesions, monitoring post-treatment recurrence, and screening the high-risk groups.
It would not be an exaggeration to say that the method became a game-changer in dermato-oncology.
This book will intend to be a guide on how to read the malignant and benign skin lesions and how to apply the clinical context to the images to enhance physician's performance in skin cancer diagnosis.
