Mycobacterial spindle cell pseudotumor (MSP) is a rare benign entity characterized by tumor-like proliferations of spindle-shaped histiocytes containing acid-fast positive mycobacteria. MSPs tend to occur predominantly in immunocompromised individuals and are concerning for a malignant neoplasm. We report a case of MSP occurring in a woman with human immunodeficiency virus and a tumor-like mass in the abdomen. A subsequent biopsy revealed MSP, which was successfully treated with antimycobacterial therapy.
分枝杆菌性梭形细胞假瘤（MSP）是一种罕见的良性病变，其特征为含有抗酸阳性分枝杆菌的梭形组织细胞呈肿瘤样增殖。MSP主要发生于免疫功能低下的个体，易被误诊为恶性肿瘤。我们报告一例发生于一名感染人类免疫缺陷病毒的女性腹部的MSP病例。随后的活检显示为MSP，经抗分枝杆菌治疗成功治愈。
