-
The chest x-ray shows a patient who had a left lung transplanted in May 2003 for cryptogenic fibrosing alveolitis, which was diagnosed post-transplant as sarcoidosis.
-
Gross pathology demonstrating the great pleural thickness and two cavities (upper lobe and superior segment of lower lobe) with fragments of fungal mass.
-
Histopathological appearance of a fungus ball. Note a conidial head resulting from fungal exposure to the air.
-
Histopathological appearance of a fungus ball caused by Scedosporium apiospermum. The presence of anneloconidia differentiates it from Aspergillus.
-
Chronic necrotising aspergillosis. Hyaline hyphal and calcium oxalate crystals obtained by needle aspirate biopsy from a diabetic patient with chronic necrotizing aspergillosis caused by Aspergillus niger (Papanicolaou, x 100).
-
Aspergillus niger fungus ball and acute oxalosis. Higher magnification of adjacent replicate section.
-
Oxalate crystals within renal tubuli (H&E, phase contrast, x 100). This patient developed acute oxalosis.
-
Lung surface. Fungus ball, severe parenchymal fibrosis and pleural thickening.
