Granuloma inguinale is a chronic bacterial infection that frequently is associated with other sexually transmitted diseases. Granuloma inguinale is characterized by intracellular inclusions in macrophages referred to as Donovan bodies. Granuloma inguinale usually affects the skin and mucous membranes in the genital region, where it results in nodular lesions that evolve into ulcers. The ulcers progressively expand and are locally destructive, as demonstrated in the image below.
The intracellular organism responsible for granuloma inguinale was initially described by Donovan over a century ago, and subsequently, the bacterium was classified in 1913 as Calymmatobacterium granulomatis. Although Anderson suggested that the organism be eponymously named Donovania granulomatosis, Carter et al discovered that the molecular structure of the causative organism was similar to Klebsiella species and reclassified the gram-negative pleomorphic bacillus as Klebsiella granulomatis.[1, 2]
The mode of transmission of granuloma inguinale primarily occurs through sexual contact; however, it is hypothesized to have low infectious capabilities because repeated exposure is necessary for clinical infection to occur. Additionally, granuloma inguinale may also be obtained through the fecal route or by passage through an infected birth canal.
Fewer than 100 cases of granuloma inguinale are reported annually, many of which are thought to be acquired during foreign travel.
Granuloma inguinale is rare in temperate climates, but it is common in the tropics and subtropics. Granuloma inguinale is endemic in Western New Guinea, the Caribbean, Southern India, South Africa, Southeast Asia, Australia, and Brazil.
The incidence is higher in blacks than in whites in the United States. The incidence is higher in native persons than in Europeans in Western New Guinea. The incidence is higher in Hindus than in Muslims in India. These differences are more likely the result of disparities in socioeconomic status and living conditions than of a racial susceptibility.
No sexual predominance is reported for granuloma inguinale.
Granuloma inguinale most commonly is seen in sexually active people aged 20-40 years.
