A retrospective analysis of 21 primary testicular tumors in childhood is presented. Histologic review revealed 4 differentiated teratomas, 14 yolk sac tumors, 1 rhabdomyosarcoma of testicular envelopes and 1 paratesticular sarcoma. One tumor could not be classified. Two patients with yolk sac tumor and the patient with the paratesticular sarcoma died. In 4 of the 14 patients with yolk sac tumor iliac and/or paraaortic lymphnodes were removed 8-15 days after hemicastration but no tumor cells were found. Of 3 children with yolk sac tumor who developed metastases, one had had prophylactic resection and another one prophylactic irradiation of the draining lymphnodes. 8 patients with yolk sac tumor received prophylactic chemotherapy, and none developed metastases. For patients with yolk sac tumor prophylactic chemotherapy is indicated, particularly if more than 2 months have elapsed between the first detection of a testicular mass and operation. In prepubertal boys with testicular teratoma no prophylactic therapy to prevent dissemination is necessary. Patients with yolk sac tumor have an age distribution comparable to that of patients with an embryonal tumor.

Accurate definition of metastases in para-aortic lymph nodes and lungs is essential in planning treatment for patients with testicular teratoma. The addition of CT scanning to routine investigation of these patients has given additional sensitivity in detection and localisation of metastases. The extent of para-aortic metastases could be clearly defined, even when bulk replacement of nodes prevented definition by lymphography. This information was used in planning the best surgical approach for para-aortic lymphadenectomy, which was done as part of combined treatment of large volume metastases.

A case of mature teratoma of the testis, representing the longest documented interval between diagnosis and metastases, is reported. A review of the clinical features, pathology, treatment and survival indicates that mature teratoma is a malignant neoplasm. The need for aggressive treat and long-term followup in patients with this tumor is stressed.

A case of adult teratoma of the testis in a 19-year-old white man is presented, The tumor metastasized to the retroperitoneal lymph nodes and the metastases were also well differentiated, benign-appearing tissues. This case suggests that even the benign-appearing components of these tumors have malignant potential. Because these tumors are malignant, they should be treated by radical orchiectomy and radical retroperitoneal dissection.

A 25-year-old patient with testicular teratoma (pathological stage I) relapsed with a solitary, symptomatic metastasis in the right humerus 8 months after unilateral orchiectomy and lymphadenectomy. Treatment consisted in three cycles of standard chemotherapy with etoposide, bleomycin and cisplatin (the last replaced by carboplatin in courses 2 and 3). No supplementary treatment proved necessary to achieve complete remission and complete physical rehabilitation. Only four cases of solitary bone metastasis of testicular germ cell tumors have been reported previously. The present case illustrates that, contrary to previous reports, symptomatic skeletal metastases of germ cell tumors can safely be treated with standard chemotherapy alone.

From January 1978 to March 1989, 92 consecutive patients with metastatic testicular teratoma have been treated with cisplatin-based chemotherapy. Thirty seven failed to achieve a complete response, and another four subsequently relapsed. These 41 have required further treatment, consisting of surgery (16 patients), radiotherapy (n = 13) and chemotherapy (n = 12). Surgery was generally used for residual masses where tumour markers were normal, radiotherapy for masses where surgery was not possible or for palliation, and second line chemotherapy was used in patients with raised serum tumour markers or in the presence of multiple inoperable pulmonary metastases. Nine of 16 (56%) patients treated surgically are disease-free, including two who had malignant teratoma in the resection specimen. Three of 13 patients irradiated are disease-free, although two of these three had subsequent excision of residual masses. All 12 patients treated with second-line chemotherapy have died. Surgical excision of residual masses appears to be the most effective way of rendering patients disease-free, providing serum tumour markers are normal. Most of these residual masses will consist of differentiated teratoma or necrosis, but it may be possible to salvage patients with residual malignant disease, providing complete clearance can be achieved. Incompletely resected malignant disease carries a poor prognosis, and incompletely resected disease that is histologically benign will run the risk of subsequent relapse. Radiotherapy provides good palliation but is much less effective than surgery as treatment for residual masses, and should only be used if complete excision cannot be accomplished.(ABSTRACT TRUNCATED AT 250 WORDS)

A case was reported concerning a successful removal of tumor thrombus extending into the right atrium through the left brachiocephalic vein and the superior vena cava. The patient was a 34-year-old man who underwent a left inguinal orchiectomy for immature teratoma of testis in June 1987. The operation was followed by another three operations for excision of lymph node metastases and five courses of cisplatin based combination chemotherapy. In December 1988, the chest CT scan film revealed filling defect in the superior vena cava and the right atrium. Thrombus was detected using echocardiography and angiography. He had no symptom, but multiple pulmonary infarcts were also detected. In February 1989, the operation was performed by means of cardio-pulmonary bypass. A soft yellowish thrombus attached to the left venous angle was removed with resection of the left brachiocephalic vein. Microscopic findings revealed that the thrombus was metastatic testicular teratoma. With further treatment after the operation, he has been disease-free for 14 months now. We conclude that in this case aggressive surgical management following chemotherapy had great value to control the disseminated testicular tumor.

We report the apparently spontaneous regression of metastatic disease in a young man who had previously undergone orchidectomy for a primary testicular teratoma. Serial serum tumour marker estimations revealed a sharp rise followed by a spontaneous decline in levels in a patient who had requested that chemotherapy be deferred for personal reasons.

This study describes the appearance of thin-walled cavities arising at the sites of pulmonary metastases from germ cell tumours treated with chemotherapy. We have termed these 'pulmonary lacunae'. They occur with a prevalence of approximately 7% in patients with multiple pulmonary metastases from testicular teratoma.

A case of teratoma of the testis presenting as sudden spontaneous hemorrhage without previous injury is described. A 25-year-old male was admitted with right scrotal pain and swelling. Though acute epididymitis or testicular torsion could not be neglected on physical examination, tumor-like echogram was obtained. High orchiectomy was performed subsequently. Macroscopically, testicular tumor with subcapsular hematoma was evident. Histopathological diagnosis was mature teratoma (pT1, No, Mo). The patient, after combined chemotherapy including cisplatin, vinblastine and peplomycin, is alive well without metastases for 15 months after operation.
