背景:胚胎癌是生殖细胞肿瘤中一种罕见的组织类型。根据我们的文献综述,转移性胚胎癌因其与淋巴瘤的高度相似性而被误诊为淋巴瘤极为罕见,尚未有报道。
方法:一名46岁中年男性出现不明原因发热,盗汗,腹胀3个月,在近6个月的时间里体重减轻了约7公斤,从临床特征和影像学检查来看,这与淋巴瘤极为相似。明确诊断后,该病例不仅获得了手术机会,而且免除了放射治疗。治疗效果良好。我们报告了一例罕见的转移性胚胎癌,这可以为胚胎性癌的诊断和治疗提供见解。
结论:腹部淋巴结转移型胚胎癌可与淋巴瘤高度相似,诊断只能根据临床表现和影像学检查,也可结合病史。肿瘤标志物和生化检查。然而,最终诊断取决于病理活检。
Embryonal carcinoma is a rare tissue type in germ cell tumors. According to our literature review, metastatic embryonal carcinoma misdiagnosed as lymphoma because of its high similarity to lymphoma is extremely rare and has not been reported yet.
A 46-year-old middle adulthood male presented with unexplained fever, night sweats, abdominal distension for 3 months, and weight loss of around 7kg during almost 6 months, which is extremely similar to lymphoma from the clinical features and imaging examinations. After a clear diagnosis, the
case not only obtained the opportunity of surgery but was also exempted from radiotherapy. The treatment effect was good. We report a
case of rare metastatic embryonal carcinoma, which can provide insight into the diagnosis and treatment of embryonal carcinoma.
Metastatic embryonal carcinoma of abdominal lymph nodes can be highly similar to lymphoma; the diagnosis can only be based on clinical manifestations and imaging examination but also combined with patient history, tumor markers and biochemical examination. However, the final diagnosis depends on pathological biopsy.
