83-Year-Old Man’s Mysterious Syphilis Case Puzzles Doctors

A rare and puzzling case in Belgium has left doctors investigating a late-stage syphilis diagnosis in an 83-year-old man. The case is notable not only for its unusual presentation – initially mimicking viral infections – but also for the decades-long latency period and the challenges it posed to medical professionals.

A Complex Presentation

The patient initially sought medical attention due to weakness on one side of his face, a condition known as unilateral peripheral facial palsy, accompanied by a brief fever. Initial tests revealed anemia, a fatty liver, and an enlarged spleen, leading doctors to suspect infections like Epstein-Barr virus or hepatitis. However, these tests all came back negative.

Did You Know? Sifilis typically develops in four stages, and the presentation of secondary symptoms after many years is considered rare.

While the facial palsy improved with a 10-day course of corticosteroids, the patient’s condition deteriorated a month later. He began experiencing joint pain, significant swelling in his feet, hands, and face, and dark-colored urine, indicating serious kidney problems.

Unearthing a Distant History

The mystery deepened with the patient’s medical history. He reported no sexual activity for 50 years, following treatment for rectal cancer two decades prior. However, the appearance of a red, scaly, and intensely itchy rash on his legs prompted a crucial admission. The patient recalled having unprotected sex with multiple partners during his time in the military and remembered a previous sexually transmitted infection, though he couldn’t recall specifics.

Diagnosis and Treatment

After extensive testing, doctors identified the bacterium Treponema pallidum in his blood and confirmed active infection of the nervous system through analysis of his cerebrospinal fluid. The patient was diagnosed with secondary syphilis accompanied by early neurosyphilis. He responded positively to a 14-day course of intravenous penicillin, with the rash, itching, and swelling gradually subsiding, and his liver and kidney function returning to normal within a month.

Expert Insight: This case highlights the potential for long-dormant infections to reactivate, particularly in individuals with compromised immune systems or those who may have received treatments that suppress immune function.

Doctors considered two possible explanations for this unusual case: reactivation of a latent infection due to steroid use, or an unreported recent exposure. Involvement of the liver and kidneys in syphilis cases is rare, occurring in less than 10 percent of cases globally.
