This disease's treatment requires a combination of sensitive antibiotics and a lengthy treatment cycle. Photodynamic therapy is still effective for patients who are unwilling to take antibiotics orally. In this case, we successfully used fire needle combined with photodynamic therapy to treat skin infectious granulomatosis caused by Mycobacterium chelonei, and achieved satisfactory results. We used fire needle to pretreat cysts and nodules, which improved the diffusion and absorption of locally applied photosensitizers and enhanced the efficacy of photodynamic therapy. However, additional clinical research is necessary to determine the efficacy and safety of fire needle combined with photodynamic therapy for cutaneous infectious granulomatosis.
