报告1例黑色素沉着性化生。一位62岁的男性出现持续两周的汽车不适病史。鼻内窥镜检查显示左侧咽鼓管开口有一个约5 mm的黑色结节，双侧输卵管环周围有几个黑点。对结节进行活检以确定组织学。光镜下可见嗜酸细胞，着色颗粒丰富，呈腺样分布。这种色素变异型良性嗜酸细胞病变是非常罕见的。(C)2004爱思唯尔爱尔兰有限公司。保留所有权利。
A case of melanin pigmented oncocytic metaplasia is reported. A 62-year-old man presented with a history of discomfort of the car of a 2 weeks' duration. Nasoscopic examination revealed a black nodule of about 5 mm at the left Eustachian opening, and several black spots were discovered around the bilateral torus tubarius. The nodule was biopsied to determine the histology. Microscopically, there were oncocytic cells with abundant pigmented granules showing glandular pattern. Such a pigmented variant of benign oncocytic lesion is very rare. (C) 2004 Elsevier Ireland Ltd. All rights reserved.
