 On pathologic examination, the RLL specimen demonstrated a large perihilar airway-centered area of cavitation with surrounding fibrosis and distal airway impaction by thick mucus, as well as several rounded foci of apparent parenchymal necrosis with yellow mucoid appearance on cut surface ( Fig. 3A ). The histologic sections corresponding to the areas of necrosis revealed consolidated parenchyma with large central liquefactive-type necrosis surrounded by organizing granulation tissue and fibrosis ( Fig. 3B ). Numerous fungal hyphae were present in the areas of necrosis, with widespread tissue and angioinvasion ( Fig. 3C ).
