OBJECTIVE
Syphilis is a well-known sexually transmitted disease, and has multiple stages and various symptoms. However, it is difficult to diagnose syphilis in patients who may have no clinical symptoms. Because of these reasons, there have been several case reports on misdiagnosis of syphilis. Generalized lymphadenopathy could be an indication of various diseases including malignancies or infections.
CONCLUSION
We report a case of a secondary syphilis in a patient with generalized lymphadenopathy detected by fluorine-18-fluorodeoxy glucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) images without any clinical symptom. Clinical examination found an ulcer on his penis and serologic tests set the diagnosis of an early stage of secondary syphilis.
目的
梅毒是一种广为人知的性传播疾病，有多个阶段和多种症状。然而，对于可能没有临床症状的患者，梅毒很难诊断。由于这些原因，已有数例梅毒误诊的病例报告。全身淋巴结病可能是包括恶性肿瘤或感染在内的各种疾病的指征。
结论
我们报告一例通过氟-18-氟脱氧葡萄糖正电子发射断层扫描/计算机断层扫描（(18)F-FDG PET/CT）图像检测到的全身淋巴结病患者的二期梅毒病例，该患者无任何临床症状。临床检查发现其阴茎有溃疡，血清学检测确诊为二期梅毒早期。
