Abstract

An 84-year-old man with a history of diffuse large B-cell lymphoma in remission who had completed chemotherapy 3 years previously was referred for imaging evaluation of disease recurrence. Abnormal accumulation in the left scrotum was demonstrated on F-FDG PET/CT. Subsequent ultrasonography showed a nodular mass lesion in the left epididymis. He then underwent left orchiectomy. Histopathological examination of the mass diagnosed smooth muscle hyperplasia/hamartoma of the left epididymis. Epididymal smooth muscle hyperplasia/hamartoma should be included as a differential diagnosis for malignant scrotal tumor.

摘要

一位 84 岁男性，既往患有弥漫性大 B 细胞淋巴瘤，缓解期，3 年前完成化疗，因疾病复发进行影像学评估。F-FDG PET/CT 显示左侧阴囊异常积聚。随后的超声检查显示左侧附睾有结节状肿块。随后行左侧睾丸切除术。肿块的组织病理学检查诊断为左侧附睾平滑肌增生/错构瘤。附睾平滑肌增生/错构瘤应作为恶性阴囊肿瘤的鉴别诊断之一。
