Syphilis human skull.
An old graveyard human syphilis skull, C 1880-1900 and probably male. In that period a lot of cemeteries were cleared because of urban expansion and population growth.

Additionally, tooth loss, alveolar abscessing, resorption are present and the left arcus zygomaticus is broken.
