This new volume of the Biopsy Interpretation Series is a practical, superbly illustrated guide to the technical and interpretive aspects of superficial skin biopsies. The book first addresses the techniques and methodology of performing a biopsy, and then discusses benign melanocytic tumors, precursors to melanoma, and melanomas. Also included are discussions of precancerous lesions of the epidermis such as actinic keratosis and of fully transformed malignant lesions arising in the skin including basal cell carcinomas and squamous cell carcinomas. Other chapters cover benign and malignant adnexal neoplasms and superficial soft tissue sarcomas which often present as cutaneous masses. A major highlight of the book is the extensive discussion of differential diagnostic considerations and their separation from the main diagnostic entities under consideration. The book features more than 400 full-color images.
