A: Hemorrhagic spot 5 to 6 mm in diameter on the upper arm; the gray area 1 to 2 mm in diameter in the center indicates necrosis. B: Pustulovesicular lesion on the finger of the same patient; the necrotic center is evident as a gray area.

FIG. 11.50. Disseminated gonococcemia. Neisseria gonorrhoeae may disseminate from mucosal surfaces via the bloodstream and produce arthritis/arthralgia and a rash. The most characteristic lesion is the hemorrhagic vesicopustule seen in the web space of the teenage girl's hand. There is a pustule on the sole of her foot.

<bold><italic>Figure 21-9</bold> Ectropion ("erosion") of the cervix.</bold> Endocervical glandular epithelium has reappeared in the transformation zone in an adult woman. The rough, red appearance led early observers to believe it involved ulceration (erosion of the mucosa) and inflammation, hence the common clinical name, "cervical erosion."

Pathogenesis of gonococcal infections. Neisseria gonorrhoea is a gram-negative diplococcus whose surface pili form a barrier against phagocytosis by neutrophils. The pili contain an IgA protease that digests IgA on the luminal surface of the mucous membranes of the urethra, endocervix, and fallopian tube, thereby facilitating attachment of gonococci. Gonococci cause endocervicitis, vaginitis, and salpingitis. In men, gonococci attached to the mucous membrane of the urethra cause urethritis ...

FIG. 9.16. A: Trichomonad in the vaginal discharge of a 17-year-old patient with gonococcal pelvic inflammatory disease. The flagellated protozoan is elliptical and somewhat larger than the adjacent polymorphonuclear leukocytes (2253 magnification). B: After suspension in saline solution for microscopy, trichomonads gradually become swollen and immobile. This balloon-shaped trichomonad is barely recognizable (2253 magnification).
