Syphilis is the infectious disease caused by Treponema pallidum.
General
- Classically affects the testis before the epididymis.[1]
- Tuberculosis[2] and gonorrhea usually affect the epididymis before the testis.
- Considered one of the TORCH infections.
Gross
Aorta:
- Wrinkled intimal surface - "tree bark" appearance.[3]
Microscopic
Features:
- Plasma cells - key feature.[4]
- Spirochetes - diagnostic.
- +/-Granulomas[5] - gumma - in the tertiary phase.[6]
DDx:
- Plasma cell neoplasm.
- Reactive changes.
- Zoon balanitis.
- Other spirochetes, e.g. Borrelia burgdorferi.
