The incidence of cutaneous melanoma has risen considerably over the last few decades, and much attention is now paid to the early diagnosis of this tumour. As a consequence, pathologists are seeing more specimens of pigmented skin lesions. Clinically new entities, such as dysplastic naevi have been identified, and have added to the complexity of the differential diagnosis. Extracutaneous melanocytic lesions are less common but are of considerable clinical importance. This book is a further addition to the "Biopsy Pathology Series", and carries on the tradition of providing a well-illustrated guide for the reporting room pathologist. This has been achieved by highlighting those well-defined histological features which should be used as diagnostic criteria. In addition, tables of diagnostic features are also included, which should facilitate easy reference. This book should be of interest to pathologists and dermatologists.
