Benign pedunculated tumours of the hypopharynx are very rare. Only a few cases of hypopharyngeal fibrolipomas have been reported. This paper adds 2 more cases with characteristic clinical features. We also present a case of recurrent fibromatous tumours of the hypopharynx with malignant change after 20 years. Malignant transformation of an originally benign hypopharyngeal tumour is extremely unusual. The clinical and pathological aspects of pedunculated benign tumours of the hypopharynx are discussed. Symptoms and signs are few and uncharacteristic. The diagnosis is difficult and often delayed. There is a risk of suffocation by laryngeal obstruction by the tumour. When the accurate diagnosis is established, the treatment of choice should be a lateral pharyngotomy with complete removal of the tumour. Long-term follow-up is recommended.
下咽良性带蒂肿瘤非常罕见。仅报道过少数几例下咽纤维脂肪瘤。本文又增加了2例具有特征性临床特征的病例。我们还报告了1例下咽复发性纤维瘤病肿瘤，20年后发生恶变。原本良性的下咽肿瘤发生恶变极为罕见。本文讨论了下咽带蒂良性肿瘤的临床和病理特征。症状和体征较少且无特征性。诊断困难且常被延误。存在肿瘤导致喉梗阻引起窒息的风险。确诊后，首选治疗方法应为外侧咽切开术并完整切除肿瘤。建议进行长期随访。
