Abstract

We report a case of a psammomatous variant of meningioma arising in a pure and mature testicular teratoma. At immunohistochemistry, the meningiomatous component showed epithelial membrane antigen, S100 protein, and vimentin positive. Benign neoplasms arising in testicular teratomas are extremely rare. To our knowledge, we have not found any such report of psammomatous variant of meningioma in a testicular teratoma and any meningioma arising in a pure and mature testicular teratoma. This is a unique phenomenon.

摘要

我们报告了一例起源于单纯成熟睾丸畸胎瘤的砂粒体性脑膜瘤变体病例。免疫组化显示，脑膜瘤成分上皮膜抗原、S100蛋白和波形蛋白呈阳性。起源于睾丸畸胎瘤的良性肿瘤极为罕见。据我们所知，尚未发现睾丸畸胎瘤中砂粒体性脑膜瘤变体以及单纯成熟睾丸畸胎瘤中出现任何脑膜瘤的相关报道。这是一种独特的现象。
