Abstract

Introduction: Mycobacterium tuberculosis is a disease seen in every tissue and organ. Although it often involves the lung and pleura, it can also progress into extrapulmonary tuberculosis. Soft tissue and bone tuberculosis are the least common of all tuberculosis types. In some cases, the lesions may appear like bone tumors or metastatic lesions. Bacteriological and histopathological studies reach a definitive diagnosis because of the biopsy. We present a case suggestive of Ewing's sarcoma with clinical and imaging findings diagnosed as soft tissue tuberculosis resulting from the biopsy.

Case: A two-year-old girl was admitted to our clinic with the complaint of palpable swelling on the left side of her chest. Ewing sarcoma was considered with the findings of Computed Tomography (CT), Magnetic Resonance Imaging (MRI), and PET-CT. Biopsy material was reported as casefied granulomatous inflammation, and M. tuberculosis complex DNA was detected by PCR examination of the tissue. The patient was successfully treated with rifampin, isoniazid, pyrazinamide, and ethambutol.

Conclusion: Today, it should be kept in mind that tuberculosis is a common disease, rarely isolated soft tissue or bone involvement, and can be confused with malignancy.
