“…A review of the English-language literature revealed that the urogenital tract is rarely involved: the most common site is the kidney, with almost 200 cases described ( 7 , 8 ), followed by the bladder ( 9 ), and the prostate ( 10 , 11 ). Ureteral localization is an exceptional finding, with only four cases of primary ES of the ureter previously reported ( 12 – 15 ).…”

“…Remarkably, due to the lack of a preoperative histological diagnosis, three of the four previously reported cases received chemotherapy only after surgery ( 12 – 14 ). In one patient, a 69-year-old woman, systemic therapy was not administered due to age and impaired cardiopulmonary function ( 15 ).…”

“…Urogenital tract involvement is a rare event, most frequently arising in the kidney, followed by the bladder and the prostate ( 7 – 11 ). As for the ureter, a primary ES is an exceptional finding: to our knowledge, there are no more than four cases described in the literature ( 12 – 15 ).…”

Case report: Primary Ewing sarcoma of the ureter, an exceptional finding of unique manifestation of disease

et al. 2023

Ewing sarcoma (ES) is the second most common malignant bone tumor in children and has also been described in adults with highly aggressive behavior. ES belongs to the small round blue cell tumor family and presents the distinctive translocation of FET-ETS family genes (85% with EWSR1), generating gene fusions. Extraskeletal ES mainly occurs in soft tissues; the urogenital tract is rarely affected, and ureteral localization is an exceptional event with only 4 cases described in the literature. Here we report the first Italian case of primary ES of the ureter, a 24-year-old young man with lower back pain and a narrowed left ureteral lumen on CT scan. ES of the urogenital tract is an almost unique condition with a nonspecific clinical presentation and a challenging diagnosis for pathologists. We encourage awareness of these exceptional events in the differential diagnosis of ureteral lesions in young patients.

“…Although not the focus of this discussion, it is worthwhile to note that several cases of primary Ewing's sarcoma in both children and adults within the bladder, ureter and kidney have been reported and treated with a combination of surgical resection, chemotherapy and radiation [20][21][22][23].…”

Ewing’s sarcoma of the male external genitalia: a case report and review of the literature

et al. 2022

Background Ewing’s sarcoma (ES) within the genitourinary tract are relatively unheard of and those within the external male genitalia are even rarer. To our knowledge, this is the first known case of primary ES within the paratesticular region in an adult. Case presentation We present a case of a 24-year-old man with a right sided testicular mass on examination that was initially characterized as an adenomatoid tumor on ultrasound. After the patient was lost to follow up over the course of 9 months, the testicular mass grew significantly and was excised with pathology revealing primary paratesticular Ewing’s sarcoma. This rare case emphasizes the importance of elucidating between the broad differentials of paratesticular masses, including the rare presentation of primary ES and adds a review of the literature of ES in the external male genitalia. Conclusions Rare differentials such as this case should be considered in patients with paratesticular masses. Further diagnostic and management algorithms for extraosseous Ewing Sarcoma, particularly in the adult population, are warranted.

Ewing sarcoma/primary neuroectodermal tumors are rare, invasive, and small round blue cell tumors. There are few reports of its occurrence in the urinary system. Here, we present the first middle-aged female patient whose Ewing sarcoma primary site was in the ureter. The main clinical manifestation was intermittent hematuria. She was in good health after complete surgical resection and adjuvant radiotherapy. To date, there has been no recurrence or metastasis. Accurate early diagnosis and appropriate treatment can help prolong survival. 18F-fluorodeoxyglucose positron emission tomography/computed tomography is expected to be an effective means of evaluating treatment effects and detecting metastasis and recurrence. In this article, besides introducing a case of Ewing sarcoma/primitive neuroectodermal tumor of the ureter, we review the literature to discuss the current status of diagnosis and treatment.
