PathogenThis section has been translated automatically.
The causative agent is Klebsiella granulomatosis, formerly known as Calymmatobacterium granulomatis or Donovania granulomatis, an encapsulated gram-negative rod (see below Klebsiella). Taxonomically, the pathogen is assigned to the Klebsiellae. It lives intracellularly (leukocytes, histiocytes; plasma cells). Culture is possible (yolk sac), but is considered difficult. Transmission through sexual intercourse.
Occurrence/EpidemiologyThis section has been translated automatically.

Clinical featuresThis section has been translated automatically.
After an incubation period of 1-12 weeks, development of non-painful, itchy pustules, papules or nodules. In the further course, increasing confluence and ulcerous decay, formation of soft, slightly bleeding, hypertrophic granulations with velvety, light red, later also yellowish smeary surface. Continuous spread of the painless, beet-like vegetations towards the groins. If not treated, abscess formation often occurs. Lymph node swellings (bubones) are atypical. Rarely, the development of lymphedema of the penis, scrotum or labia is possible due to obstruction of the lymphatic channels, especially as a result of secondary infections. In MSM, anal infestation is possible.
