• Spirochaete -Treponema pallidum
• Cannot be cultivated
• Genome sequenced in 1998
• Humoral & cell-mediated immune response
• Endarteritis obliterans
• Untreated T. pallidum survives for decades
• Protective immunity –but re-infection occurs
• Transmission rate 20-60%

Repeat Syphilis
Urgent Urology OPD
U/S testis 3 heterogeneous lesions
• 10x9x7 mm R testis -? Breach tunica
• 7x6x4 mm L testis
• 7x6x4 mm R epididymis
• Tumour markers -normal
• Rectal biopsy –normal
CT Thorax abdomen pelvis with contrast
Clinical indication:Testicular lesions on ultrasound. ? Tumour. Staging examination.
Findings:1. A couple of subpleural nodules are seen within the left upper and lower lobes which measure up to 4 mm. The lungs are otherwise clear.2. No adenopathy within the thorax.3. Normal appearances of the solid viscera.4. The lower rectum appears slightly thick walled with some mild inflammatory change within the surrounding fat. Remainder of the bowel appears unremarkable.5. There are some small volume bilateral iliac chain and para-aortic lymph nodes but these all subcentimetre in size and not significant as per CT size criteria.6. Moderate OA change at L4-5 and mild OA change at L5-S1. No destructive bone lesion. Conclusion:The lower rectum appears slightly bulky with inflammatory change in the surrounding mesentery. PR examination is advised to rule out a lesion here. I can see no further significant abnormality.
