<unk>  (from Greek Malako "soft" + Plako "plaque") is a rare inflammatory condition which makes its presence known as a papule, plaque or ulceration that usually affects the genitourinary tract. However, it may also be associated with other bodily organs. It was initially described in the early 20th century as soft yellowish plaques found on the mucosa of the urinary bladder. Microscopically it is characterized by the presence of foamy histiocytes (called von Hansemann cells) with basophilic inclusions called Michaelis–Gutmann bodies. It usually involves gram-negative bacteria.
