Abstract:
Mycobacterial spindle cell pseudotumor (MSP) is an uncommon granulomatous inflammation often found in immunocompromised patients, especially those with HIV. This case report discusses an 18-year-old female with congenital HIV, who presented with severe epigastric pain, nausea, and noteworthy lymphadenopathy. Imaging studies identified lobulated masses, and a core needle biopsy confirmed the diagnosis of MSP, revealing spindle-shaped histiocytes and acid-fast bacilli. Additionally, we reviewed nine MSP cases documented since 2017.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
