Abstract：
Isolated intraparotid neurofibromas are exceptionally rare and often associated with neurofibromatosis type 1 (NF1). Diagnosing these tumors proves challenging because of the clinical resemblance to primary salivary gland masses. This case report details an 18-year-old with a painful, enlarging parotid mass, diagnosed through fine needle aspiration biopsy (FNAB) revealing myxoid stroma and spindle cells. Magnetic resonance imaging confirmed a plexiform neurofibroma involving the parotid gland and facial nerve. Histopathology validated the diagnosis, emphasizing the importance of cytological and radiological correlation. Notably, the absent NF1 association makes this case unique. Surgical excision with facial nerve reconstruction was performed, highlighting the complexity of managing such rare intraparotid neurofibromas. Awareness of this entity is crucial for accurate diagnosis and appropriate management.
摘要：
孤立的颈动脉内神经纤维瘤非常罕见，通常与1型神经纤维瘤病（NF1）有关。由于与原发性唾液腺肿块的临床相似，因此诊断这些肿瘤具有挑战性。这份病例报告详述了一名18岁的患者，腮腺肿块增大,通过细针穿刺活检（FNAB）诊断，发现粘液样基质和梭形细胞。磁共振成像证实了累及腮腺和面神经的丛状神经纤维瘤。组织病理学证实了诊断,强调细胞学和放射学相关性的重要性。值得注意的是,缺席的NF1协会使这种情况独特。行面神经重建手术切除，强调管理这种罕见的颈动脉内神经纤维瘤的复杂性。对该实体的认识对于准确诊断和适当管理至关重要。
