Granuloma venerum is a genital ulcerative disease caused by the bacterium Klebsiella granulomatis that is transmitted through sexual contact or close personal contact. It primarily affects sexually active individuals between 20-40 years old. The disease progresses through three stages, starting with red bumps or pimples that spread and erode the skin, developing into deep ulcers with foul smelling discharge in later stages. Diagnosis involves sexual history, physical exam, tissue biopsy, and culture tests. Treatment consists of a multi-week course of antibiotics like azithromycin or doxycycline until sores have fully healed.
