The rhabdoid malignant tumor was individualized by Haas et al. as an independent entity within the kidney malignant neoplasms in 1981. From its histopathological characteristics, different cases of rhabdoid extra-renal tumor were documented. This aspect has been also recognized in a wide heterogeneous group of tumors (carcinoma, melanoma, mesothelioma and mesenchymal tumors). The diagnosis of extrarenal rhabdoid tumor is based on the presence of a proliferation of epithelioid cells with large nuclei, prominent nucleoli, abundant eosinophilic cytoplasm, and conspicuous cytoplasmic intermediate filaments, which compress the nuclei. In this article we present the case of a 50-year-old male patient with a malignant maxillary tumor with characteristic rhabdoid features. Its differential diagnosis will be discussed. The literature will also be reviewed.
1981年，哈斯等人将横纹肌样恶性肿瘤确定为肾恶性肿瘤中的一个独立实体。根据其组织病理学特征，记录了不同病例的肾外横纹肌样肿瘤。这一特征在广泛的异质性肿瘤群体（癌、黑色素瘤、间皮瘤和间叶性肿瘤）中也得到了认可。肾外横纹肌样肿瘤的诊断基于上皮样细胞的增殖，这些细胞具有大核、明显的核仁、丰富的嗜酸性细胞质以及明显的细胞质中间丝，中间丝压迫细胞核。在本文中，我们报告了一例50岁男性患者，患有具有典型横纹肌样特征的上颌恶性肿瘤。将讨论其鉴别诊断，并对相关文献进行综述。
