<unk>  is a bacterial disease caused by Klebsiella<unk> tis (formerly known as Calymmatobacterium<unk> tis) characterized by genital ulcers. It is endemic in many less-developed regions. It is also known as donovanosis,<unk>  genitoinguinale,<unk>  tropicum,<unk>  venereum,<unk>  venereum genitoinguinale, lupoid form of groin ulceration, serpiginous ulceration of the groin, ulcerating<unk>  of the pudendum, and ulcerating sclerosing<unk> . Oral manifestations are also notably seen. The lesions of oral cavity are usually secondary to active genital lesions. The disease often goes untreated because of the scarcity of medical treatment in the countries in which it is found. In addition, the painless genital ulcers can be mistaken for syphilis. The ulcers ultimately progress to destruction of internal and external tissue, with extensive leakage of mucus and blood from the highly vascular lesions. The destructive nature of donovanosis also increases the risk of superinfection by other pathogenic microbes.
