The skin manifestations of secondary syphilis, termed syphilid. Show macular, papular and papulosquamous rashes in most cases, but may show lots of other clinical findings.
We report a case of syphilid simulating purpura annularis telangiectodes in 25-year-old male who had a history of genital ulcer 2 months ago. The skin lesion showed diffuse erythematous, 1-3 cm sized, telangiectatic annular patches and purpuric
plaques
on both lower extremities and discrete papulosquamous rashed on both soles. The results of the serologic test for syphilis was found to be reactive to 32 dilution in serum VDRL test and positive is serum TPHA test. Histopathologically, we could
observe
the obscuring of dermo-epidermal junction, coat-sleeve-like perivascular infiltrate composed of mononuclear cells and a few plasma cells, and endothelial swellings. After the treatment with benzathine penicillin G, the titer of serum VDRL test
was
decreased abruptly to 4 dilution and the skin lesions disappeared completely. ( Kor J Dermatol 1994 ; 32(5) : 926~930)
