Lesions of skin and arthritic knee joints due to Neisseria gonorrhoeae blood-borne pathogens. Gonorrhea, caused by Neisseria gonorrhoeae, if left untreated will enter the blood, thereby, spreading throughout the body. As is shown here, such full body dissemination may manifest itself as skin lesions and arthritic joints.
