Mycobacterial Spindle Cell Pseudotumor Presenting as Peritoneal Masses in a Suspected Case of Human Immunodeficiency Virus

Mycobacterial spindle cell pseudotumor is a rare entity occurring in immuno-compromised patients mostly with acquired immunodeficiency syndrome, organ transplant and immuno-suppressive therapy. It occurs in various body sites and most commonly non-tuberculous mycobacteria are the causative agent followed by Mycobacterium tuberculosis. It is characterized by proliferation of spindle shaped histiocytes with acid fast bacilli. It histologically mimics spindle cell neoplasms including kaposi’s sarcoma. We present a case of Mycobacterial spindle cell pseudotumor in an immunocompromised patient with peritoneal mass and discuss the characteristic findings.
