The pathology of fungal disease in the lung.

The gross and histological appearance of pulmonary mycotic disease is rarely pathognomonic for a particular entity. Tissue obtained through an invasive procedure is usually necessary for a specific diagnosis. Pathological diagnosis is directed by the pattern of inflammation and based on the morphological identification of fungi. The interventional radiologist plays a critical role in the diagnosis of pulmonary mycoses by obtaining additional material for culture. An open and inquisitive collaboration between the radiologist and pathologist can improve diagnostic accuracy for both specialists.
