'Burned-out' Seminomatous Testicular Tumour Diagnosed as Retroperitoneal Metastasis, A Rare Case

Abstract

"Burned-out testicular tumour" is extremely rare. Burned-out phenomenon describes partially or completely regressed germ cell tumours of the testes diagnosed after metastases in several parts of the body; including the mediastinum, cervical and axillary lymph nodes, retroperitoneal lymph nodes, and the retroperitoneal region. Physical examination of the testicles reveals non-specific findings. A 31-year-old male presented with abdominal and back pain. The physical examination findings were unremarkable. Imaging with computerized tomography showed a retroperitoneal mass. Excision of the retroperitoneal mass and the paraaortic, paracaval, and retroperitoneal lymph nodes was performed. The postoperative period was uneventfuland he was discharged on the postoperative 5^thday. The postoperative pathological examination of the specimen reported a metastatic seminoma. Investigation of the underlying cause of a retroperitoneal mass in young adults requires including metastasis of burned-out germ cell tumours in the differential diagnosis. Further case reports on this rare type of tumour are required so that all potential risk factors will be defined and treatment protocols will be updated to optimize the management of the patients with burned-out germ cell tumours.

Retroperitoneal Metastaz ile Bulgu Veren Burned-Out Seminomatöz Testiküler Tümör, Nadir Bir Olgu

Abstract

"Burned-out testis tümörü" nadir görülen bir tümör türüdür. Burned out fenomeni, testisteki germ hücreli tümörün parsiyel ya da tamamen regrese olup, mediastinel, servikal, aksiller, retroperitoneal lenf nodları veya retroperitonal bölgeye metastaz ile bulgu vermesi olarak tanımlanır. Yapılan fizik muayenede testis muayenesi olağandır. 31 yaşında erkek hasta sırt ve karın ağrısı yakınması ile başvurdu. Yapılan fizik muayenesinde patolojik bulguya rastlanılmadı. Çekilen abdomen tomografide retroperitoneal kitle saptandı. Retroperitonela kitle eksizyonu, paraaortik, parakaval ve retroperitoneal lenf nodu diseksiyonu uygulandı. Hastanın postoperatif dönemi komplikasyonsuz olup, postoperatif beşinci gün taburcu edilmiştir. Patoloji sonucu, seminom metastazı olarak raporlanmıştır. Retroperitoneal kitle ile karşımıza çıkan genç hastalarda burned out tümörlerin metastazları olabileceği akılda tutulmalıdır. Burned-out tümörlerin tedavi seçenekleri zamanla değişebilir. Farklı risk faktörlerini tanımlamak ve tedavinin optimize edilmesine yardımcı olabilmek için daha geniş olgu serileri yayınlanmalıdır.
