Abstract | RATIONALE: PATIENT CONCERN: A 56-year-old male patient visited our hospital with a palpable mass in the right supraclavicular fossa which was later confirmed as metastatic squamous cell carcinoma. After completion of concurrent chemoradiation therapy, a focal consolidation was developed in the right upper lobe apex where radiation was applied. The patient did not have any symptoms or signs of infectious disease. DIAGNOSIS: Pulmonary TB was diagnosed through polymerase chain reaction (PCR) test and culture of sputum. INTERVENTION: Anti-TB medication was started. OUTCOME: The patient was tolerable to anti-TB medication and the size of TB lesion gradually decreased. LESSON: A suspicion of pulmonary TB should be given to patients with new infiltrates in radiation port due to impact of radiation therapy on local infection barriers and patients' immune system.
