Saprophytic aspergillosis

Saprophytic aspergillosis, consisting of fungal growth without tissue invasion. Examples include airway colonization as in asthma, cystic fibrosis, and COPD mycetoma or an invasion of necrotic tissue, usually the infarcted lung.

Aspergillosis may also develop within the spine (Fig. 3.36), within the pelvis, with tubo-ovarian masses or ureteral compression, or within the renal graft, as a fungus ball (saprophytic colonization of a cavity by fungal hyphae, without invasion of the adjacent tissues) (Johnston et al. 2004).
