In a 61-year-old man with known poroma of right lower abdomen, malignant transformation to porocarcinoma was suspected and confirmed by biopsy. PET/CT was requested for tumor staging, which revealed high FDG uptake in the known skin nodules located in the right side of abdominal and chest wall and identified further some adenopathy in the right axillary. All nodules and axillary lymph nodes were removed, and diagnosis of eccrine porocarcinoma was confirmed. The primary tumor and secondary lesions of porocarcinoma show a high glucose metabolism; thus, PET/CT could be useful for staging, follow-up, and detection of recurrence of patients with eccrine porocarcinoma.
在一位 61 岁男性中，右下腹部已知的汗孔瘤发生恶变，被怀疑为汗孔癌，并通过活检得到证实。为进行肿瘤分期，行 PET/CT 检查，结果显示位于右侧腹部和胸壁的已知皮肤结节和右侧腋窝的一些淋巴结摄取 FDG 增高。所有结节和腋窝淋巴结均被切除，诊断为小汗腺汗孔癌。原发性肿瘤和汗孔癌的继发性病变表现为高葡萄糖代谢；因此，PET/CT 可用于小汗腺汗孔癌患者的分期、随访和复发检测。
