A photograph of part of the upper lung lobe of an immunosuppressed patient. The lung tissue shows extenive areas of necrosis due to invasive colonisation.
-
A photograph of a cavity in the upper lobe of the lung of a patient with ankylosing spondylitis. Such cavitation,which may be confused with prior tuberculosis, can follow fibrosis.
-
Plugs stained with Methenamine/silverActively growing mycelia of the fungus are a deep brown/black. Counterstaining shows the dense mucus of the plugs as predominantly orange.

Sputum from an asthmatic patient showing plugs(casts). The development of plugs coincided with an increased prevalence and severity of episodes of asthma
