ABSTRACT: This chapter covers birthmarks and other anomalies found in infants. Naevi are classified according to the tissue of origin: epidermis, connective tissue, fat and muscle. Melanocytic naevi are discussed elsewhere. Vascular birthmarks are divided into haemangiomas and vascular malformations. Developmental defects include those resulting from defective embryogenesis, particularly of branchial structures and the neuraxis. Particular attention is drawn to cutaneous markers of non-cutaneous defects, such as spinal dysraphism, and those such as aplasia cutis and vascular naevi which may be the presenting sign of a syndrome. Clinical features, pathology, investigation, management, complications and differential diagnosis are covered comprehensively

ABSTRACT: Nevus sebaceous of Jadassohn is a hamartoma with a combination of abnormalities of the epidermis, hair follicles, and sebaceous and apocrine glands. Herein, we discuss the results of an extensive literature review on the topic of nevus sebaceous with a particular focus on the debate about the necessity for prophylactic excision. We also focus on the documentation of associated malignant tumors that were reported to develop within NS. In addition to reporting the number and types of neoplasms, we documented the recommendations of all authors for therapeutic handling of these nevi.
