case_images: Pathologic results by the TBLB revealed the mass in the right hilar region as chronic inflammation with necrosis, and the DNA fragment of Mycobacterium tuberculosis (Mtb) was found in the specimen (Figure 2). Thus, the patient received a CT-guided percutaneous lung biopsy at the periphery of the same mass (Figure 3). The pathology showed a poorly differentiated squamous cell carcinoma (Figure 2).
