Primary penile lymphoma is an extremely rare neoplasm. We present a case of 63-year-old man with painless diffuse pe- nile swelling and retention of urine. Biopsy from the penile swelling demonstrated CD20+ diffuse large B-cell lymphoma. Staging was performed using fluorine-18-fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET-CT) and revealed a FDG avid penile mass with enlarged and FDG avid multiple inguinal and aortocaval lymph nodes. A follow-up FDG PET-CT scan after eight cycles of combination chemotherapy showed complete remission of the dis- ease. Thus, FDG PET-CT should be integrated in management protocols of rare primary penile lymphoma.
原发性阴茎淋巴瘤是一种极为罕见的肿瘤。我们报告一例 63 岁男性，表现为无痛性弥漫性阴茎肿胀和尿潴留。阴茎肿胀处活检显示弥漫性大 B 细胞淋巴瘤，CD20+。采用氟-18-氟代脱氧葡萄糖（FDG）正电子发射断层扫描-计算机断层扫描（PET-CT）进行分期，结果显示 FDG 摄取活跃的阴茎肿块伴肿大且 FDG 摄取活跃的多个腹股沟和腹主动脉旁淋巴结。在接受 8 个周期联合化疗后进行的 FDG PET-CT 随访扫描显示疾病完全缓解。因此，FDG PET-CT 应整合到罕见原发性阴茎淋巴瘤的管理方案中。
