We present the case of a 37-year-old man with plasma cell granuloma affecting the middle ear and mastoid. At magnetic resonance imaging scan, the lesion appeared as a homogeneously enhancing mass of soft tissue replacing the majority of the mastoid bone and causing vascular compression. After surgical resection, microscopic examination showed predominantly plasmacytes, and histochemical studies confirmed a polyclonal origin consistent with nonneoplastic plasma cell granuloma. We believe this is the first case report of plasma cell granuloma affecting the middle ear and mastoid.
我们报告了一例37岁男性患有累及中耳和乳突的浆细胞肉芽肿病例。在磁共振成像扫描中，病变表现为均匀强化的软组织肿块，取代了大部分乳突骨并导致血管受压。手术切除后，显微镜检查显示主要为浆细胞，组织化学研究证实其起源为多克隆性，符合非肿瘤性浆细胞肉芽肿。我们认为这是首例关于累及中耳和乳突的浆细胞肉芽肿的病例报告。
