Gastric syphilis: The great imitator in the stomach.

Syphilis is resurging worldwide. Here, we present the case of a 33-year-old heterosexual man who presented with a 3-week history of epigastric pain, nausea, emesis, and 8 kg weight loss. He was subsequently diagnosed with gastric syphilis, based on reactive syphilis serological testing and Treponema pallidum found in gastric biopsy specimens.

Fulminant amebic colitis in an HIV-infected homosexual man.

We present a case of fulminant amebic colitis in a human immunodeficiency virus (HIV)-infected homosexual man. The patient developed colonic perforation over a short time despite empirical therapy with metronidazole, and underwent right hemicolectomy. Amebic colitis was pathologically diagnosed by identifying invasive trophozoites of Entamoeba in a surgical specimen.

Group G streptococcal bacteremia and vertebral osteomyelitis in a homosexual man with amebic colitis.

We present a case of bacteremia caused by group G streptococci (GGS) and vertebral osteomyelitis in a homosexual man with amebic colitis. The organism likely entered the blood via the inflamed intestinal mucosa resulting from amebiasis. Arthritis of both hands, which probably represented poststreptococcal reactive arthritis, was also observed.
