This book describes unusual cases of cutaneous lymphomas and is of special interest for clinicians and pathologists dealing with the vexing subject of cutaneous lymphoma. In addition to the case description, it gives the clinical, histological, and in most cases also the phenotypical features and the results of molecular techniques. A commentary puts the observations into the context of cutaneous lymphomas. Related papers are cited. The book will be especially helpful in cases which do not fit into the normal spectrum of cutaneous lymphomas. Rare entities of cutaneous lymphomas are demonstrated with high-quality pictures (4-color) and a concise text in an appealing format throughout the book. The new WHO/EORTC-Classification of Cutaneous lymphomas includes more than 30 entities of Cutaneous T-cell and Cutaneous B-cell lymphomas.
