Paratesticular Rhabdomyosarcoma Associated with Tuberculosis.

We report a 16-year-old male patient diagnosed with paratesticular rhabdomyosarcoma and mediastinal tuberculous lymphadenitis. The differential diagnosis between high or early stage of rhabdomyosarcoma and tuberculosis (TB) was critical in this patient without a history of TB. Unexpected lymphadenopathies detected during the staging of patients with malignancy should be carefully evaluated, and TB should be taken into consideration in the differential diagnosis especially in underdeveloped and developing countries. Unnecessary additional treatments increase the rate of mortality and morbidity because of upstaging of cancer. Further, TB reactivation can be seen during chemotherapy because of immunosuppression.
