An 85-year-old man has been experiencing weight loss, night sweats, and a dry cough for several months; recently, he has begun coughing up sputum with tinges of blood in it. Following a chest X-ray showing some white spots on his lungs, an AFB stain and culture were ordered, and both were positive for the presence of AFB. He has been PPD positive since his twenties. What is your diagnosis?
