mucormycosis (mu″kor-mi-ko´sis) a mycosis due to fungi of the order Mucorales, such as species of Rhizopus and less often Mucor or Absidia, usually an opportunistic infection in debilitated or immunocompromised patients. Organisms enter through the respiratory tract, digestive tract, or a skin lesion, and then invade blood vessel walls and are disseminated in the blood; spread along nerve trunks also occurs. The disease may affect the head and neck, the respiratory tract, the digestive tract, or more rarely the skin. Clinical manifestations range from chronic to fulminant. Fungi of class Entomophthorales cause a similar condition called entomophthoromycosis. Called also phycomycosis and zygomycosis. cerebral mucormycosis
fulminant, usually fatal mucormycotic infection of the brain; it may be caused by dissemination of fungi from a distant site
or by direct extension of rhinocerebral mucormycosis. pulmonary mucormycosis
mucormycosis of the lung; symptoms include bronchitis, cavitation, hemoptysis, and often death within a month. rhinocerebral mucormycosis
cerebral mucormycosis in which the original site of infection is in the ethmoid, sphenoid, or maxillary sinuses, the palate, or the pharynx.
