Melanomas are usually cutaneous in origin but rarely can also arise from the mucosal linings in the body. Sinonasal melanomas arise from the mucosa of the nasal cavity and paranasal sinuses, which account for approximately 50% of mucosal melanomas in the body. 18F fluorodeoxyglucose positron emission tomography-computed tomography (F-FDG PET/CT) has proven its role in malignant melanoma in staging especially in stage III and IV disease, restaging, assessing response to therapy and had affected in treatment change in significant number of cases. We present a case of sinonasal melanoma who underwent FDG PET/CT for staging and showed cervical lymph node and marrow metastases.
黑色素瘤通常起源于皮肤，但也很少可源自体内的黏膜内衬。鼻窦黑色素瘤起源于鼻腔和鼻窦的黏膜，约占体内黏膜黑色素瘤的50%。18F氟脱氧葡萄糖正电子发射断层扫描-计算机断层扫描（F-FDG PET/CT）已证明其在恶性黑色素瘤分期中的作用，尤其是在III期和IV期疾病中，还可用于再分期、评估治疗反应，并且在大量病例中影响了治疗方案的改变。我们报告一例鼻窦黑色素瘤患者，其接受了FDG PET/CT检查以进行分期，结果显示有颈部淋巴结和骨髓转移。
