A case of metastasizing ectopic thymoma arising in the right thoracic cavity and infiltrating the right lung and pleura in a fashion reminiscent of diffuse pleural mesothelioma is presented. An involuted, non-neoplastic thymus was demonstrated microscopically in the anterior mediastinum. No case of thymoma showing the combination of ectopic location and biological malignancy has yet been reported in the literature. The pathogenesis of ectopic thymuses and thymomas is discussed from an embryological standpoint. The discrepancy between morphology and biological behaviour of thymomas is also mentioned with a review of the literature.
本文报告一例起源于右胸腔并以类似弥漫性胸膜间皮瘤的方式浸润右肺和胸膜的转移性异位胸腺瘤。显微镜下在前纵隔发现一个萎缩的、非肿瘤性胸腺。文献中尚未报道过具有异位位置和生物学恶性特征组合的胸腺瘤病例。从胚胎学角度讨论了异位胸腺和胸腺瘤的发病机制。还结合文献回顾提到了胸腺瘤形态与生物学行为之间的差异。
