11/239. Postirradiation aortic sarcoma demonstrated by magnetic resonance angiography.

    This is the first ever reported case of a radiation-induced aortic sarcoma. This patient had symptoms and signs initially interpreted as a pulmonary embolus. The extent of the disease was demonstrated with magnetic resonance imaging and magnetic resonance angiography, in particular, allowing rapid surgical intervention. ( info)

12/239. scleromyxedema: possible association with seminoma.

    Although scleromyxedema has been associated with neoplasm in rare instances, the literature showed no evidence of association with seminoma. We report a 43-year-old man who presented with a scleromyxedema and relapsed seminoma. The skin lesions of scleromyxedema cleared completely on treatment of seminoma with chemotherapy. ( info)

13/239. Primary seminoma of the retroperitoneum.

    A rare case of primary seminoma in the retroperitoneum is described. Ultrasound detected a huge hypoechoic mass and correlative computed tomography showed a midline, homogeneous, lobulated mass in a man who presented for anuria. ( info)

14/239. Father-son testicular tumors: evidence for genetic anticipation? A case report and review of the literature.

    BACKGROUND: The etiology of testicular carcinomas is unknown. Father-son testicular tumors represent an important subset of patients because the sons have a 6- to 10-fold increase in the risk of developing a testicular tumor compared with the general population, suggesting a possible genetic component in the etiology of the disease. Genetic anticipation has been established for several diseases and manifests itself clinically with earlier age of onset (AO) of disease or with increased severity of disease in children compared with their parents. methods: We report only the 13th case of pure seminoma occurring in both a father and a son. The most striking feature of our case study was a 27-year difference in the AO between father and son. A review of the literature from 1972 through 1999 provided 47 cases of father-son testicular tumors in which sufficient information was available to compare the AO and the severity of the disease in the fathers (G1) and the sons (G2). RESULTS: The mean AO for G1 was 43.3 ( /- 1.6) years compared with a mean AO for G2 of 27.0 ( /- 1.0) years for all 47 cases (P < 0.01). For fathers presenting with a pure seminoma, the mean AO was 45.9 ( /- 1.8) years for G1 compared with 27.0 ( /- 1.1) years for G2 (P < 0.01). For fathers presenting with a nonseminomatous tumor, the mean AO in G1 was 37.9 ( /- 2.6) years and 26.9 ( /- 1.8) years for G2 (P < 0.01). For the entire group of 47 cases, disease was more severe in G2 compared with G1 in 43% of cases, of equal severity in 47% of cases, and less severe in G2 compared with G1 in 10% of cases. CONCLUSIONS: Genetic anticipation may be responsible for many father-son testicular tumors. ( info)

15/239. Primary testicular seminoma in a patient with a history of extragonadal non-seminomatous germ cell carcinoma.

    Extragonadal germ cell carcinoma represents between 3% and 5% of all germ cell carcinomas. A metachronous primary germ cell carcinoma is exceedingly rare in these patients. We report the eighth case, which occurred in a 29-year-old man who presented with testicular seminoma 7 years after his initial presentation with extragonadal non-seminomatous germ cell carcinoma. The seven other patients also presented with extragonadal non-seminomatous germ cell carcinoma, followed subsequently by testicular seminoma in 6 patients and non-seminomatous germ cell carcinoma in the seventh. The mean time to presentation was 8 years. Although rare, this case emphasizes the need for long-term surveillance, including testicular evaluation of patients with a history of extragonadal germ cell carcinoma. ( info)

16/239. Significance of simultaneous determination of serum human chorionic gonadotropin (hCG) and hCG-beta in testicular tumor patients.

    BACKGROUND: Simultaneous determinations of human chorionic gonadotropin hormone (hCG) and hCG-beta frequently produce discrepancies, that is when hCG or hCG-beta is normal, the other is elevated. Accordingly, we examined the significance of simultaneous determination of serum hCG and hCG-beta in testicular tumors. methods: Simultaneous determination of hCG and hCG-beta was performed in 54 patients with testicular seminoma and 74 with non-seminomatous testicular tumors. RESULTS: For detection of seminoma patients, hCG-beta was more effective than hCG because hCG-beta was positive in 83% (45/54) of the patients and hCG was positive in 50% (27/54). In non-seminomatous testicular tumor cases, hCG-beta was positive in 74% (55/74) and hCG was positive in 82% (61/74). The cases of hCG<1.0 mIU/mL and HCG-beta>0.1 ng/mL were significantly more frequently seen in patients with seminoma than in those with non-seminomatous testicular tumor (P < 0.001). Fourteen patients had recurrent tumor. At recurrence, only hCG was elevated in nine cases, only hCG-beta was elevated in two cases and both in one case. For diagnosis of falsely positive hCG, testosterone administration was effective because after testosterone administration, serum hCG levels became undetectable (< 1.0 mIU/mL) within one week in three examined cases. CONCLUSION: Human chorionic gonadotropin-beta was a better marker of seminoma than hCG. For earlier detection of recurrence, both markers should be examined. For diagnosis of falsely positive hCG, testosterone administration was effective. ( info)

17/239. Metastatic extragonadal seminoma associated with cardiac transplantation.

    A 37-year-old man who had successfully undergone cardiac transplantation for dilated cardiomyopathy presented with a history of severe pain over his left shoulder, rib cage and thoracic spine. Clinical examination revealed the presence of bony tenderness over these sites, but there was no other clinical evidence of malignancy. Further investigations suggested the presence of multiple bony metastases. Bone biopsy revealed extensive bone marrow infiltration by large undifferentiated cells showing pronounced cytoplasmic vacuolation with a striking granulomatous reaction. Immunocytochemistry revealed these anaplastic cells to be cytokeratin and placenta-like alkaline phosphatase positive but S100, CD30 and lymphoid marker negative. Analyses by in situ hybridisation of these cells revealed no evidence of Epstein-Barr virus infection. overall the pathology suggested a diagnosis of metastatic seminoma. Confirmation of this diagnosis was obtained by the analysis of serum human chorionic gonadotrophin which was elevated at 90 IU/l. In the absence of testicular or retroperitoneal disease, it is very likely that this unusual case of metastatic seminoma was related to the patient's immunosuppressive therapy, which at diagnosis included cyclosporin and prednisolone. The patient was successfully treated with cisplatin based chemotherapy and decreased immunosuppression and remains in complete remission one year after completion of chemotherapy. seminoma is an uncommon complication of prolonged immunosuppression with very few cases being described in the literature post-organ transplantation. This case shows that the clinical presentation of this treatable tumour in this patient population can be unusual and difficult to diagnose. ( info)

18/239. Healing of superior vena cava defect in mediastinal seminoma with invasion.

    We present an unusual case of mediastinal seminoma with direct intraluminal invasion into the superior vena cava (SVC) and extension to the right atrium. magnetic resonance imaging demonstration of the SVC defect due to tumor invasion was important for determining treatment strategy because rapid posttherapeutic tumor regression may increase the risk of SVC rupture. Gradual healing of the SVC defect at the tumor entrance site was attained using a tailored treatment plan with radiotherapy and chemotherapy. ( info)

19/239. Intracranial dural metastasis of mediastinal seminoma--case report.

    A 24-year-old male presented with a rare intracranial dural metastasis from a mediastinal germ cell tumor infiltrating the superior vena cava, pericardium, ascending aorta, and lung. Routine chest radiography incidentally revealed the abnormal mediastinum, which was partially resected after median sternotomy, followed by radiotherapy. One year after the radiotherapy, magnetic resonance imaging revealed a right parasagittal tumor mimicking a meningioma. Partial tumor removal was performed. Two cycles of chemotherapy with carboplatin and etoposide were then performed, and the residual tumor almost completely disappeared. The histological diagnosis of both the mediastinal and intracranial tumors was pure seminoma. Sections of metastatic tumor revealed several thick fibrous septa and numerous epithelioid granulomas infiltrated by plasma cells, intermingled between the clusters of tumor cells. Follow up of patients apparently in remission from mediastinal seminoma without evidence of advanced or recurrent disease at other sites is recommended. ( info)

20/239. seminoma metastatic to the prostate resulting in a rectovesical fistula.

    We report an unusual presentation of metastatic seminoma within the prostate gland. Histological diagnosis was obtained using trans-rectal ultrasound guided prostatic biopsy. The patient developed a rectovesical fistula after ten weeks of chemotherapy, which healed following a complete radiological response to treatment ( info)
