We describe the FDG PET/CT findings in an exceedingly rare case of metastatic pilomatrix carcinoma (PC). A 76-year-old man, who underwent incisional biopsy of a soft-tissue mass in the frontal scalp that revealed PC, was referred for an F-FDG PET/CT scan for staging purposes. PET/CT showed areas of increased radiotracer uptake corresponding to frontal mass and unsuspected lung lesions, which were later confirmed as metastases from PC at histological analysis. Clinical condition deteriorated rapidly, and the patient died 3 months after the initial diagnosis.
我们描述了一例极为罕见的转移性毛母质癌（PC）的 FDG PET/CT 表现。一位 76 岁男性，因额头皮下软组织肿块行切开活检，结果显示为 PC，为了分期目的，行 F-FDG PET/CT 扫描。PET/CT 显示放射性示踪剂摄取增加的区域与额部肿块和未怀疑的肺部病变相对应，这些病变后来在组织学分析中被证实为 PC 转移。临床状况迅速恶化，患者在初始诊断后 3 个月死亡。
