An unusual presentation of a granular cell tumor is reported with a review of the natural history and pathologic characteristics of this tumor. Our patient was asymptomatic and presented with a mass in the inferior right neck on routine physical examination. Preoperative radiologic evaluation suggested a parathyroid adenoma but the normal parathormone level was inconsistent with this diagnosis. At surgery, a firm mass was identified inferior to the right lobe of the thyroid gland and was found to represent a granular cell tumor densely adherent to the trachea. This case demonstrates a unique presentation for this relatively rare neoplasm which was treated with complete surgical resection.
本文报告了一例颗粒细胞瘤的罕见表现，并对该肿瘤的自然史和病理特征进行了综述。我们的患者无症状，在常规体格检查中发现右颈部下方有一肿块。术前影像学评估提示甲状旁腺腺瘤，但正常的甲状旁腺激素水平与该诊断不符。手术中，在甲状腺右叶下方发现一个质地坚硬的肿块，发现是一个与气管紧密粘连的颗粒细胞瘤。该病例展示了这种相对罕见肿瘤的独特表现，采用了完整的手术切除进行治疗。
