The lesion on this patient’s left hand was due to the systemic dissemination of the Neisseria gonorrhoeae bacteria. Though sexually transmitted, and involving the urogenital tract initially, a Neisseria gonorrhoeae bacterial infection can become disseminated systemically, manifesting itself as a cutaneous erythematous lesion anywhere on the body.
