小児の表在臓器の病変の多くは頸部に認められるが，他の部位に生じる皮下組織の病変にも知っておきたいものがある．頸部病変を先天性疾患，嚢胞性腫瘤，充実性腫瘤，感染，血管腫と血管奇形に分類して，その他に頸部以外の病変を含めた．それぞれの領域の疾患の超音波検査所見を解説した．先天性疾患では発生学を踏まえて診断する必要があるため，発生についても要点を解説した．また，血管腫と血管奇形は臨床的に重要なISSVA（the international society for the study of vascular anomalies）分類に準じて述べた．
Many superficial lesions in the pediatric population are located in the neck, while subcutaneous lesions located in other regions are also important to know. These cervical diseases are classified into congenital anomalies, cystic masses, solid masses, inflammation, hemangiomas, and vascular malformations. Others are included in the miscellaneous category. As the differential diagnosis of these lesions is made from an embryological point of view, ultrasonographic findings of these diseases are described with embryological understanding. Hemangiomas and vascular malformations are discussed based on the classification of the International Society for the Study of Vascular Anomalies.
