Tuberculosis of the pubic symphysis

Area of Science:

• Medical Microbiology
• Orthopedics
• Public Health

Background:

• Tuberculosis (TB) is a major public health concern in India, with extrapulmonary TB accounting for a significant portion of cases.
• Osteoarticular tuberculosis, a form of extrapulmonary TB, represents approximately 13% of all extrapulmonary cases, commonly involving lymph nodes.
• The typical pathway for osteoarticular TB is hematogenous or lymphatic spread from a reactivated latent focus, often pulmonary.

Observation:

• The spine is the most frequent site for skeletal tuberculosis, followed by the hip, knee, and ankle joints.
• While TB can affect any bone or joint, involvement of the pubic symphysis is exceptionally rare.
• This report details a rare case of pubic symphysis tuberculosis in a 25-year-old female presenting with a thigh swelling.

Findings:

• The case underscores that tuberculosis can manifest in unusual skeletal locations.
• Diagnosis of osteoarticular TB may not always correlate with a demonstrable active infection site elsewhere in the body.
• The presentation of pubic symphysis tuberculosis highlights the need for a broad differential diagnosis in cases of localized swelling.

Implications:

• This case expands the understanding of the anatomical distribution of osteoarticular tuberculosis.
• It emphasizes the importance of considering TB in the differential diagnosis of inflammatory conditions affecting uncommon skeletal sites.
• Further research into rare presentations of osteoarticular TB can improve diagnostic accuracy and patient management.
