本文报告外耳道耵聍腺瘤11例,并介绍 Wetli(1972)的组织学分型:(1)腺样囊性癌,(2)腺癌,(3)腺瘤,(4)多形性腺瘤。此分类法对本病的诊断和估计预后帮助很大。本组包括腺样囊性癌10例和腺癌1例。我们认为,耵聍腺瘤的确诊靠病理学检查。恶性类型对放射无效。外科切除为首选治疗,切除范围次定于组织学类型。如果恶性类型未能在早期根治性切除,终归于死亡。本病需长期随访。
This article reports 11 cases of parotid adenoma of the external auditory canal and introduces the histological classification of Wetli (1972): (1) adenoid cystic carcinoma, (2) adenocarcinoma, (3) adenoma, and (4) pleomorphic adenoma. This classification helps the diagnosis and prognosis of the disease. This group included adenoid cystic carcinoma in 10 cases and adenocarcinoma in 1 case. We believe that the diagnosis of salivary adenoma depends on pathological examination. Malignant types are not effective for radiation. Surgical resection was the preferred treatment, and the resection range was scheduled for histological type. If the type of malignancy fails to be radically removed in the early stages, it will eventually be death. The disease needs long-term follow-up.
