Basal cell adenoma is an uncommon benign salivary gland neoplasm, presenting isomorphic basaloid cells with a prominent basal cell layer. Basal cell adenoma arising from the nasal septum is exceptionally rare. Reports on positron emission tomography with 2-deoxy-2-fluorine-18-fluoro-D-glucose (18FDG-PET) imaging for basal cell adenoma are limited. Here, we present the case of a 49-year-old man who had the symptoms of intermittent repeated bleeding from the left nose for half a year. 18FDG-PET scanning showed increased accumulation of 18FDG with its characteristic benign pathology has a potential to malignancy. After removal of the mass, the patient became symptom free. Pathology showed basal cell adenoma. The evidence of active and growing cells was present in the specimen.
基底细胞腺瘤是一种罕见的涎腺良性肿瘤，由形态一致的基底样细胞构成，基底细胞层明显。起源于鼻中隔的基底细胞腺瘤极为罕见。关于2-脱氧-2-氟-18-氟代-D-葡萄糖正电子发射断层扫描（18FDG-PET）用于基底细胞腺瘤成像的报道有限。在此，我们报告一例49岁男性患者，其半年来出现左侧鼻腔间歇性反复出血症状。18FDG-PET扫描显示18FDG摄取增加，其具有特征性的良性病理表现，但有恶变可能。肿物切除后，患者症状消失。病理显示为基底细胞腺瘤。标本中存在活跃生长细胞的证据。
