Abstract

Germ cell tumors may manifest as a burned-out testis tumor in theabdomen that is characterized by lymph node metastasis or anothermanifestation of a metastatic neoplasm with a partially or totally histologicallyregressed, occult primary tumor in the testis.An 8-month-oldboy presented with abdominal mass and hypospadias. On physical examination,a palpable abdominal mass in the left abdomen, the absenceof the left testis in the scrotum, and hypospadias were found. Colorflow Doppler ultrasonography revealed a well-defined, hypoechoicmass with no vascular flow. A laparoscopy was performed. No testis wasfound in the inguinal region and the abdomen. An amputated, smoothsurface with brown color mass was found in the retrovesical area of theperitoneum. The mass was removed, and macroscopic examination ofthe lesion yielded a well-defined, stone hard mass. No live tissue wasfound histopathologically. Immunohistochemical studies revealed relativelypositive findings for germ cell tumor.To our knowledge, this casereport is the first burned-out germ cell tumor that developed in the undescendedtestis in children. Here, we present the clinical and imagingfindings of a burned-out germ cell tumor of the undescended testis.

Özet

Burned-out tümörü, testiste germ hücreli tümörün kısmen yada tamamen gerilemesiyle ortaya çıkan bir durumdur. Klinik olarak lenf nodu metastazı yada metastatik bir neoplazmin başka bir bulgusunun saptanması ile tanımlanabilir. Sekiz aylık erkek hasta karın ağrısı ve hipospadias şikayeti ile polikliniğimize başvurdu. Fizik muayenesinde karnın sol tarafında ele gelen kitle, skrotumda sol testisin ele gelmemesi ve hipospadias bulguları mevcuttu. Renkli doppler ultrasonografide vasküler akımın alınamadığı hipoekoik kitle tanımlandı. Laparoskopide inguinal bölgede ve karın içerisinde sol testisin olmadığı görüldü. Ancak retrovezikal alanda kahve renkli, düzgün yüzeyli ve sert kıvamda kopmuş bir kitle görüldü ve çıkarıldı. Histopatolojik incelemede canlı doku yoktu. İmmünohistokimyasal çalışmada ise germ hücreli tümör olarak değerlendirildi. Olgumuz çocuklarda inmemiş testiste gelişen ilk burned out germ hücreli tümördür. Biz bu olgu sunumunda inmemiş testiste gelişen burned out germ hücreli tümörün klinik ve radyolojik görüntülerini sunmayı amaçladık.
