We report a rare case of bilateral carcinoma of the ears in a 41-year-old man. The second tumor developed from the left mastoidectomized middle ear cavity eight years after the complete healing of the first tumor, which probably originated in the glands of the right external auditory canal.
我们报告了一例41岁男性双侧耳部癌的罕见病例。第二例肿瘤在第一例肿瘤完全愈合八年后，从左侧行乳突切除术后的中耳腔发展而来，第一例肿瘤可能起源于右侧外耳道腺体。
