Toward a full understanding of the skin adrexa and associated tumors, an accurate and detailed visual record of the various structures en- countered is essential. Such a comprehensive survey has, however, hith- erto been lacking in works on dermatology; this situation I attempt to remedy in the present atlas by presenting a collection of my own cases over the years. I took almost all the photomicrographs myself using a Nikon Biophot microscope. I would like to express my deep gratitude to Prof. Hitoshi Hatano, Department of Dermatology, School of Medicine, Keio University, who reviewed this book and consented to its publication. I am especially grateful to Dr. Junya Fukuda, Chief Pathologist, Kawasaki Municipal Hospital, who helped in diagnosing routine histological sections of the skin and gave invaluable advice with this book. I am enormously in- debted to Mr. Soichi Narutomi, Chief Technician, Section of Pathology, Kawasaki Municipal Hospital, who produced first-class prints from 35-mm films. I must express my deep thanks to the late Mr.Shin Takeichi, Head of Photography, Department of Pathology, School of Medicine, Keio University, who kindly took photomicrographs for me for many years; some of these are included in the present volume. lowe a great deal to Associate Prof. Kan Niizuma, Department of Derma- tology, School of Medicine, Tokai University, who kindly arranged for this book to be published by Springer-Verlag. Finally, I should like to acknowledge the efforts and goodwill of Springer-Verlag Tokyo. KINY A ISHIKAWA Spring, 1987 Contents Structure of the Adnexa .
