Mycobacterial spindle cell pseudotumor (MSP) is a rare benign lesion characterized by local proliferation of spindle-shaped histiocytes containing acid-fast mycobacteria. Most reported cases of MSP occur in the lymph nodes, skin, spleen, and brain in patients who are immunocompromised, particularly following solid organ transplant and in those with AIDS. This is a case report of a patient with AIDS who presented with cough, generalized weakness, and fatigue, who was found to have multilobar lung masses that were MSP, which to our knowledge has not yet been reported in the literature.
分枝杆菌梭形细胞假瘤（MSP）是一种罕见的良性病变，其特征是局部增殖含有抗酸分枝杆菌的梭形组织细胞。大多数报道的 MSP 病例发生在免疫功能低下的患者的淋巴结、皮肤、脾脏和大脑中，特别是在实体器官移植后和 AIDS 患者中。这是一例 AIDS 患者的病例报告，该患者表现为咳嗽、全身无力和疲劳，被发现有多发性肺肿块，这些肿块是 MSP，据我们所知，这在文献中尚未报道过。
