Inguinal lymphadenitis caused by Entamoeba histolytica: case report and literature review.

Liver abscesses are the most common manifestation of extraintestinal infection by Entamoeba histolytica. Involvement of other sites, including the peritoneum, pericardium, brain, or genitourinary tract, is unusual. We describe a case of inguinal necrotizing lymphadenitis caused by E histolytica. Our patient responded well to surgical drainage, metronidazole, and paramomycin therapy. A literature review of genitourinary and other uncommon sites of E histolytica infection is included.
