A 64-year-old Caucasian male is admitted to the hospital with fatigue, cough, hemoptysis, and difficulties with nasal breathing. At admission, his vital signs are as follows: temperature of 38.1 C, the pulse of 114 bpm, BP of 145/95 mm Hg, and RR of 22 breaths/min. Physical examination reveals moderate puffiness of the face and dullness on percussion and reduced breathing over the left lung. Chest x-ray examination reveals several cavitating opacities in the left lung. Urinalysis detects hematuria and mild proteinuria. PPD test reading in 72 hours reveals 5-mm erythema; sputum microscopy for AFB is negative. Two images below represent gross and microscopic appearance of the patient’s lung.
