Parotid tumours in childhood are rare. Four patients under 16 years old having parotidectomy are described and the literature is reviewed. The presentation, pathology and prognosis of parotid tumours in childhood is different to that seen in adults. Half of the parotid tumours in childhood are malignant but most are of low grade. Rapid growth, if present, may be the only clue of malignancy and facial nerve palsy or cervical node metastasis have rarely been described. Adequate surgical excision with facial nerve preservation is the treatment of choice and radical neck dissection is rarely necessary. Radiotherapy should be avoided and the prognosis is very favourable. It is difficult to differentiate clinically between benign and low-grade malignant tumours and because of the high incidence of malignancy, all parotid tumours in childhood should be suspected of being malignant until proven otherwise.
儿童腮腺肿瘤较为罕见。本文描述了4例16岁以下接受腮腺切除术的患者，并对相关文献进行了综述。儿童腮腺肿瘤的临床表现、病理及预后与成人不同。儿童腮腺肿瘤半数为恶性，但多数为低级别。若肿瘤生长迅速，可能是恶性的唯一线索，而面神经麻痹或颈部淋巴结转移则鲜有报道。治疗首选保留面神经的充分手术切除，很少需要根治性颈清扫术。应避免放疗，预后非常良好。临床上很难区分良性和低级别恶性肿瘤，鉴于恶性肿瘤的高发病率，儿童所有腮腺肿瘤在未被证实为其他情况之前均应怀疑为恶性。
