Description:This photomicrograph reveals “Donovan bodies” in a tissue sample used to diagnose granuloma inguinale.
Diagnosis of granuloma inguinale is based on the appearance of encapsulated bacilli called Donovan bodies. These are safety pin-shaped microorganisms that appear inside infected tissue cells under a microscope.

Granuloma Inguinale:

Clinical description:

A slowly progressive ulcerative disease of the skin and lymphatics of the genital and perianal area caused by infection with Calymmatobacterium granulomatis. A clinically compatible case would have one or more painless or minimally painful granulomatous lesions in the anogenital area.

Laboratory criteria for diagnosis:

Demonstration of intracytoplasmic Donovan bodies in Wright or Giemsa-stained smears or biopsies of granulation tissue
