Abstract

During the preoperative diagnostics of an 80-year-old male patient prior to a planned endarterectomy, an unclear space-occupying lesion was detected in the right nasopharyngeal cavity. It proved to be a dense soft tissue space-occupying lesion of the right maxillary sinus. The histological investigations revealed a partially necrotically decomposed malignant tumor below normal respiratory mucosa free from dysplasia. This case demonstrates the difficulties in differential diagnostics, particularly involving (aberrant) expression of cytokeratin.

摘要

在一名80岁男性患者计划进行动脉内膜切除术的术前诊断过程中，在右侧鼻咽腔发现了一个不明占位性病变。结果证明它是右侧上颌窦的一个致密软组织占位性病变。组织学检查显示，在无发育异常的正常呼吸黏膜下方有一个部分坏死分解的恶性肿瘤。该病例显示了鉴别诊断的困难，特别是涉及细胞角蛋白的（异常）表达。
