Precautions on Contact Dermatoscopy and Other Practices in the Pandemic of COVID-19 *by Walid Al-Zyoud and Dana Erekat*

Preface

Dermatoscopy is a fast, easy-to-learn, low-cost, and non-invasive diagnostic method utilizing the Rayleigh scattering phenomenon to visualize epidermal and subepidermal structures. It has become increasingly popular for allowing visualization of structures that are impossible to see with the naked eye. This book presents comprehensive

Following the Introductory Section, the second section of this book discusses basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), neoplasms responsible for more than 95% of all skin cancer cases worldwide. Chapter 2 by Prof. Larisa Prpic Massari summarizes the data on epidemiology, genetic background, and the clinical and dermatoscopic presentation of the most common histopathological variants of BCC. In Chapter 3, Dr. Alise Balcere presents an up-to-date review on actinic keratosis (AK) and intraepithelial carcinoma (IEC). This chapter discusses the clinical and histological classification of AK, the SCC progression model, and dermatoscopic clues to AK and IEC.

The third section of this book presents information on melanocytic lesions with a focus on combined nevi, which are common melanoma simulators. In Chapter 4, Prof. Jelena Stojkovic-Filipovic and Miljan Vlahovic define combined nevi and discuss their most common variants and their matching dermatoscopic and histopathologic

The fourth section of this book focuses on special sites. In Chapter 5, Dr. Wojciech Adamski, an ophthalmologist, and Dr. Kinga Adamska, a dermatologist, present their collection of pigmented lesions affecting the eyelid margin and share their approach to

The fifth section includes two miscellaneous chapters. Chapter 6 by Dr. Çetinarslan Tubanur, Dr. Ece Gökyayla, and Prof. Aylin Türel Ermertcan presents the authors' research on inflammoscopy of palmoplantar dermatoses. Rich descriptions of dermatoscopic clues of psoriasis, eczema, lichen planus, and lichen nitidus, a wide range of keratodermas, and fungal and bacterial infectious diseases (including syphilis) are the best examples of where dermatoscopy can be applied. Finally, Chapter 7 by Dr. Walid Al-Zyoud and Dr. Dana Erekat summarizes the precautions taken in the dermatological office during the COVID pandemic. The chapter stratifies procedures into risk groups and advises on how to safely manage patients, including those requiring skin checkups.

I wish to express my gratitude to all the authors for their contributions and IntechOpen
