Ewing's sarcoma masquerading as chronic osteomyelitis: a case report.

Area of Science:

• Oncology
• Infectious Diseases
• Orthopedic Surgery

Background:

• Tuberculous chronic osteomyelitis is a challenging infection often requiring prolonged treatment.
• Ewing sarcoma is a rare bone cancer typically affecting younger individuals.
• Misdiagnosis between these conditions can lead to delayed treatment and adverse outcomes.

Purpose of the Study:

• To highlight an unusual case of adult female Ewing sarcoma initially misdiagnosed as tuberculous chronic osteomyelitis.
• To emphasize the diagnostic challenges and potential for misidentification between these two distinct pathologies.
• To underscore the importance of considering rare diagnoses in persistent or atypical presentations.

Main Methods:

• Case report of an adult female patient.
• Review of clinical presentation, diagnostic workup, and treatment course.
• Comparison of clinical and radiological features of Ewing sarcoma and tuberculous osteomyelitis.

Main Results:

• The patient initially received treatment for tuberculous chronic osteomyelitis.
• Diagnosis of Ewing sarcoma was significantly delayed due to the initial misdiagnosis.
• The unusual presentation underscores the potential for these conditions to masquerade each other.

Conclusions:

• Ewing sarcoma can present atypically in adults, mimicking chronic infectious processes like tuberculous osteomyelitis.
• Diagnostic delays can occur when these conditions are confused, potentially leading to poorer prognoses.
• Increased awareness and consideration of differential diagnoses are vital for timely and accurate diagnosis.
