Abstract
Germ cell tumor is the most common malignancy in men aged 15-35 years. About five percent of the malignant germ cell tumors are extragonadal in origin. However metastatic deposit of seminoma in retroperitoneal lymph node without presence of any tumor in the testes is uncommon. We present a case of metastatic retroperitoneal seminoma as the initial presentation of a burned out testicular primary. The patient presented with pain in abdomen and back. Ultrasonography of the testis showed a lesion, which after high inguinal ochidectomy was reported as fibrosis only, without any tumor, i.e. burned out phenomenon. A laparotomy biopsy of the retroperitoneal lymph node mass was taken and reported as metastatic seminoma after immunohistochemistry. After 14 months of chemotherapy there is a residual lymph node of less than 3cm, serum tumor markers are normal and the patient is under observation.
