case_images: Soft tissue tuberculosis of the right forearm was identified by postoperative pathology, which showed fibrocystic tissue with granulation tissue and granuloma formation, inflammatory cell infiltration (Figure 3A), and multinucleated giant cells in some areas (Figure 3B). Staining for acid fast bacilli were positive (Figure 3C) and the IS6110 gene was detected by quantitative real-time PCR (qPCR) using the Mycobacterium tuberculosis Complex kit (Cat.801176, Zeesan Biotech, Xiamen, China), the result showed positive amplification (Figure 4).
