Unusual testicular metastatic localization of Ewing’s sarcoma: case report

Abstract

Abstract Background Ewing’s sarcoma is a rare form of bone cancer that can also affect soft tissues. In some cases, it can spread to other parts of the body, including the testicles, causing testicular metastases. To our knowledge, no testicular metastasis of Ewing’s sarcoma has been reported in the literature. Summary We report an original case of an 18-year-old patient who presented with bilateral testicular masses revealing an exceptional metastasis of metastatic bone Ewing sarcoma under chemotherapy for one year. It was difficult to diagnose synchronous bilateral testicular metastases of Ewing’s sarcoma due to the low frequency of these metastases. However, given the history of metastatic cancer, the data from the clinical examination, and the results of ultrasound, it should be considered and included in the differential diagnosis. Conclusion Despite the uncommon occurrence of secondary testicular metastasis, it should be considered in the differential diagnosis when encountering such a clinical presentation.
