Analysis of Diagnosis and Treatment Strategies for Parapharyngeal Space Tumors With Follicular Dendritic Sarcoma

Parapharyngeal space tumor is a tumor that occurs in the parapharyngeal space. Parapharyngeal space tumors are uncommon, accounting for about 0.5% of head and neck tumors. Eighty percent of them are benign and 20% are malignant. The pathologic types of tumors are varied, mainly neurogenic tumors and salivary gland tumors. Follicular dendritic sarcomas are much rarer, with an inert biological behavior and a low-grade malignant sarcoma. Clinicians face difficulties in the management of this lesion. Therefore, a comprehensive analysis of the management of this disease is necessary.
