A 50-year-old man presented with a persistent cough refractory to antibiotic therapy. Chest x-ray revealed a 5.0 cm mass lesion with central cavitation. A PPD was negative. Biopsy attempts were non-diagnostic, and the mass was eventually resected given a high clinical and radiographic suspicion of malignancy. The lobectomy specimen revealed a cavitary mass with a mixed fibrotic and gelatinous cut surface.
