Contents

Hair diseases represent a significant portion of cases seen by pediatric dermatologists. It is, therefore, a great pleasure to see the publication of this diagnostic atlas for pediatric hair disorders. The authors are well known in international trichology, especially in the field of hair problems in childhood. This book is easy to follow and represents a timely contribution to both clinical dermatology and pediatrics.

During the past decade, many investigators involved in clinical and basic research have been attracted by the field of hair disorders. In particular, molecular analysis of genetic hair disorders is developing rapidly. The examination of the status of hair growth, including microscopic analysis of hair shafts, represents a visual approach that may yield important hints for the diagnosis of complex genetic syndromes. This book will help both dermatologists and pediatricians improve their skills in the differential diagnosis of hair diseases.

Why pediatric trichology? For many reasons it is necessary to treat the special problems of hair diseases of children. For example, the full-blown picture of Menkes kinky hair disease is virtually never seen in adult patients. Loose anagen hair very rarely occurs in adults, and trichotillomania is far more frequently seen in childhood.

Dermatologists are in the enviable situation of being able to study many disorders with simple diagnostic techniques. Hair is easily accessible to examination but, paradoxically, hair examination is often ignored by non-dermatologists. The present text will serve as an important tool in the diagnostic processes used in daily practice, and it will help, for example, to distinguish certain acquired and genetically determined hair diseases. The informative iconographic material of this book will stimulate and encourage physicians to perform microscopic analyses of hair shafts and cooperate with dermatologists experienced in this special field of medicine.

It is a privilege to be associated, even in this peripheral form, with this text that will be a most welcome addition for all those dealing with hair diseases of children.

Pediatric trichology covers a wide field of study that includes pediatric and dermatological cases. It comprises extremely common entities (alopecia areata, trichotillomania) and others that are rare and more difficult to diagnose (hair dysplasias, genodermatosis). In many of the clinical pictures, hair alteration (diffuse or localized, alopecia, cicatricial or non-cicatricial, acquired or congenital) is a fundamental clue for clinical diagnosis (Menkes syndrome, Netherton syndrome, trichothiodystrophy). Knowledge of the possible clinical associations in all these entities (follicular hyperkeratosis, ichthyosis, cataracts, seizures) may also contribute to a diagnosis.
