Follicular dendritic cell sarcoma (FDCS) of the parapharyngeal space is a rare malignant tumor. Only eleven cases of FDCS of the parapharyngeal space have been reported in English literature. Most of the reported cases developed tumor recurrence within 1 year or had metastasis. Because of the rarity of FDCS in the parapharyngeal space and peculiar histology, it can be misdiagnosed as undifferentiated carcinoma or meningioma. Therefore, pathologists should be aware of the existence of FDCS in this location. This paper aims to report a unique case of FDCS of the parapharyngeal space without recurrence in 26 months follow up with a review of the literature.
咽旁间隙滤泡树突状细胞肉瘤(FDCS)是一种罕见的恶性肿瘤。英文文献中仅报道了11例咽旁间隙FDCS。大多数报道的病例在1年内出现肿瘤复发或发生转移。由于咽旁间隙FDCS罕见且组织学特殊,可被误诊为未分化癌或脑膜瘤。因此,病理学家应意识到该部位存在FDCS。本文旨在报告1例独特的咽旁间隙FDCS病例,随访26个月无复发,并对文献进行复习。
