Syphilis is a bacterial infectious disease that has a venereal mode of transmission. As seen here, tertiary syphilis results in numerous lesions on the skull vault. Presentation of caries sicca on the parietal bones and occipital can be seen when the person is severely affected, and in this case, there is advanced sclerotic healing. Syphilitic lesions often affect the outer table of the skull, leaving the inner table spared.nnSpecifications:nn1:1 scalenPolyurethane resin castn2-part skull (separate cranium & jaw)nSkull Length 19 cm (7.5 in.)nSkull Width 12.9 cm (5 in.)nSkull Height 17.5 cm (7 in.)nnProduct of Bone ClonesnPlease be advised that this product is made to order and will require additional lead time.
