<unk>  chiefly affects the central face, usually beginning in the nose before extending onto paranasal sinuses, cheeks, upper lip and pharynx. The disease is acquired usually by breathing in the spores of the fungus, which then infect the tissue of the nose and paranasal sinuses, from where it slowly spreads. It can attach to underlying tissues, but not bone. It can be acquired by direct infection through a small cut in the skin such as an insect bite. Thrombosis, infarction of tissue and spread into blood vessels does not occur. Deep and systemic infection is possible in people with a weakened immune system. Infection causes a local chronic granulomatous reaction.
