A 30-year-old man was admitted with a chief complaint of left-sided scrotal enlargement, and was diagnosed as having testicular seminoma after orchiectomy. Eight years earlier, he had been treated with chemotherapy for an extragonadal germ cell tumor, without orchiectomy, leading to complete remission. His histological diagnosis at that time was a germ cell tumor, composed of choriocarcinoma and embryonal carcinoma. He was followed up without testicular biopsy. Routine pretreatment testicular biopsy in patients with extragonadal germ cell tumor is controversial, but regular long-term follow up and information on the risk of developing a metachronous testicular tumor are needed after treatment of extragonadal germ cell tumors, even when there seems to be a partial or complete clinical response.

D016609 Neoplasms, Second Primary Abnormal growths of tissue that follow a previous neoplasm but are not metastases of the latter. The second neoplasm may have the same or different histological type and can occur in the same or different organs as the previous neoplasm but in all cases arises from an independent oncogenic event. The development of the second neoplasm may or may not be related to the treatment for the previous neoplasm since genetic risk or predisposing factors may actually be the cause.

D018239 Seminoma A radiosensitive, malignant neoplasm of the testis, thought to be derived from primordial germ cells of the sexually undifferentiated embryonic gonad. There are three variants: classical (typical), the most common type; anaplastic; and spermatocytic. The classical seminoma is composed of fairly well differentiated sheets or cords of uniform polygonal or round cells (seminoma cells), each cell having abundant clear cytoplasm, distinct cell membranes, a centrally placed round nucleus, and one or more nucleoli. In the female, a grossly and histologically identical neoplasm, known as dysgerminoma, occurs. (Dorland, 27th ed) Seminomas
