Two cases of progressive hearing loss due to middle ear tumours are described. The histological characteristics numbered intraluminal mucin production and neuroendocrine features, as shown by argyrophilia and ultrastructural demonstration of dense core granules. These tumours have been known by many different names, reflecting the controversies relating to their presumed histogenesis and differentiation. The currently preferred designation is middle ear adenoma, and these two cases provide further evidence for dual lines of differentiation.
本文描述了两例因中耳肿瘤导致的进行性听力损失病例。组织学特征包括腔内粘蛋白产生和神经内分泌特征,嗜银染色及致密核心颗粒的超微结构显示可证实这些特征。这些肿瘤有许多不同的名称,反映了关于其假定的组织发生和分化的争议。目前首选的名称是中耳腺瘤,这两个病例为双重分化谱系提供了进一步的证据。
