Soft tissue tuberculosis: a series of 11 cases

Area of Science:

• Infectious Diseases
• Rheumatology
• Orthopedics

Background:

• Soft tissue tuberculosis (TB) is a rare manifestation of Mycobacterium tuberculosis infection.
• Clinical presentation can be nonspecific, mimicking other inflammatory or neoplastic conditions.
• Risk factors include immunosuppression, foreign birth in endemic areas, and prior TB exposure.

Observation:

• A retrospective review identified 11 cases of soft tissue TB between 1988 and 1994.
• Patients often presented with swelling and pain, with a mean duration of 4.4 months.
• Commonly associated conditions included collagen vascular disorders, kidney transplant, and immunosuppressive therapy.

Findings:

• Foreign birth was a significant factor in most cases.
• Trauma and history of previous TB were noted in some patients.
• Coexisting active TB at other sites was present in half of the cases.
• Treatment involved debridement/drainage and multi-drug therapy for 6-12 months, with frequent medication intolerance.

Implications:

• Soft tissue TB should be considered in the differential diagnosis of unexplained soft tissue masses, particularly in at-risk populations.
• Prompt diagnosis and appropriate anti-TB therapy are essential for favorable outcomes.
• Awareness of potential relapses and medication intolerance is important for patient management.
