Abdominal wall mycobacterial spindle cell pseudotumor lesion

Area of Science:

• Pathology
• Infectious Diseases
• Histopathology

Background:

• Mycobacterial spindle cell pseudotumor (MSCP) is an uncommon proliferation.
• It is characterized by spindle-shaped histiocytes containing acid-fast bacilli.
• MSCP typically affects immunocompromised individuals at diverse anatomical locations.

Observation:

• This report details a case of MSCP presenting as an abdominal wall mass.
• The patient was immunocompromised, a common demographic for this condition.
• The presentation involved specific histological features.

Findings:

• Histological examination revealed spindle-shaped histiocytes.
• Acid-fast bacilli were identified within the lesional cells.
• The abdominal wall mass exhibited characteristic features of MSCP.

Implications:

• This case expands the known anatomical sites for MSCP.
• It underscores the importance of considering MSCP in immunocompromised patients with unusual masses.
• Accurate histological diagnosis is crucial for appropriate management.
