Paratesticular Rhabdomyosarcoma Associated with Tuberculosis

Area of Science:

• Oncology
• Infectious Diseases
• Pediatric Medicine

Background:

• Rhabdomyosarcoma is a rare soft tissue sarcoma in children and adolescents.
• Tuberculosis (TB) remains a significant global health issue, particularly in developing nations.
• Accurate diagnosis is crucial for effective treatment and patient outcomes.

Observation:

• A 16-year-old male presented with paratesticular rhabdomyosarcoma and mediastinal tuberculous lymphadenitis.
• The differential diagnosis between rhabdomyosarcoma staging and TB was challenging due to the absence of a prior TB history.
• Unexpected lymphadenopathies during malignancy staging require thorough investigation.

Findings:

• The case highlights the importance of considering tuberculosis (TB) in the differential diagnosis of unexpected lymphadenopathies in cancer patients.
• Misdiagnosis can lead to inappropriate treatments, potentially worsening cancer staging and patient prognosis.
• Tuberculosis reactivation is a risk during chemotherapy due to immunosuppression.

Implications:

• Clinicians should maintain a high index of suspicion for TB in patients with unexplained lymphadenopathy, especially in endemic areas.
• Integrating infectious disease screening into cancer staging protocols can improve diagnostic accuracy.
• Prompt and correct diagnosis prevents unnecessary morbidity and mortality associated with delayed or incorrect cancer treatment.
