1/645. Primary carcinoid of testis.

    A patient with primary solid carcinoid of the testis is described and 8 previous cases are reviewed. Ultrastructural study of our case disclosed pleomorphic granules, typical of the insular type carcinoid of the intestine of midgut derivation. Primary solid testicular carcinoid appears to behave as a benign neoplasms. None of these patients had evidence of metastases or the carcinoid syndrome for periods ranging from 20 months to 25 years.

2/645. Mixed testicular tumor in immunosuppressed patient: case report.

    A 30-year-old man who was maintained on immunosuppressants following renal transplantation had seminoma with teratoma of the right testis 3 months postoperatively. The temporal relationship in the development of the tumor in the presence of immunosuppressants strongly suggests the importance of the immunodefense mechanism in the control, development or growth of the neoplasm.

3/645. life-threatening germ cell tumor arising in cryptorchidism: a case report.

    We report a case of life-threatening germ cell tumor in abdominal cryptorchidism. A 32-year-old man presented with a three-month history of dyspnea, loss of appetite, general weakness and a large abdominal mass. physical examination revealed vacancy of the right scrotal contents. Chest radiograph showed massive left pleural effusion. Abdominal ultrasound revealed ascites, right hydronephrosis and the presence of an 18 x 15-cm heterogeneous echogenic mass in the upper abdomen and right iliac fossa. Abdominal computerized tomography (CT) revealed the presence of a large heterogeneous tumor and an enlarged (4 x 4-cm) retroperitoneal lymph node. Sonoguided needle biopsy of the abdominal mass demonstrated malignant cells of an uncertain type and origin. serum alpha-fetoprotein (AFP) and beta-human chorionic gonadotropin (beta-HCG) concentrations were elevated. Under the diagnosis of metastatic nonseminomatous germ cell tumor in abdominal cryptorchidism, the patient received three cycles of cisplatin-based combination chemotherapy followed by resection of the abdominal residual cryptorchid tumor. Histologically, the tumor showed marked necrosis without viable cancer. The patient had remained free of disease for seven months following surgery.

4/645. Neuro-ophthalmologic manifestations of a paraneoplastic syndrome and testicular carcinoma.

    The authors report two patients with testicular cancer who exhibited supranuclear gaze disorders as a manifestation of a paraneoplastic brainstem encephalomyelitis. In the first patient, neuro-ophthalmic dysfunction was accompanied by a prominent limbic encephalitis whereas in the second patient, an unusual, mixed pendular and jerk nystagmus was manifested. neuroimaging revealed an enhancing hypothalamic mass in the first patient and was negative in the second. Blood from both patients contained an antibody previously reported in a patient with limbic encephalitis and testicular cancer.

5/645. Primary carcinoid tumor of the testis: immunohistochemical, ultrastructural and dna flow cytometric study of two cases.

    Primary testicular carcinoid tumor, occupying 0.23% of testicular neoplasm, is a rare and indolent neoplasm with the potential for distant metastasis. We present two cases of primary pure carcinoid tumor of the testis. Both patients were 36 years old. physical examination revealed testicular mass with and without tenderness. The preoperative serum levels of beta-human chorionic gonadotropin and alpha-fetoprotein were normal and neither patient had carcinoid syndrome. The tumors measured 7.5x6x4 cm and 5.5x5x4 cm in size. Histologically, immunohistochemically and ultrastructurally, the tumors showed typical features of the carcinoid tumor. Case 1 showed extensive tumor necrosis and vascular invasion. dna flow cytometric analysis showed aneuploidy with dna index of 1.47 and S G2M of 14.0% in case 1 and tetraploidy with dna index of 1.96 and S G2M of 22.1% in case 2. Both patients have been well without any signs of metastasis after operation for 24 months in case 1 and for 16 months in case 2.

6/645. Metastatic testicular teratoma of the nasal cavity: a rare cause of severe intractable epistaxis.

    Malignant neoplasms of the nasal cavity and paranasal sinuses are uncommon. choriocarcinoma is a highly malignant germ cell tumour occurring in the reproductive organs. Metastasis may be principally by the lymphatic route as in other germ cell tumours but choriocarcinoma is also known to spread haematogenously. We present a rare case of metastatic choriocarcinoma to the nasal cavity from testicular teratoma presenting with intractable epistaxis in a 32-year-old Caucasian male, who ultimately succumbed to this disease.

7/645. Familial ovarian germ cell cancer: report and review.

    Ovarian germ cell cancers are rare malignancies accounting for less than 5% of all ovarian cancers. We present a family in which three closely related women were diagnosed with ovarian germ cell malignancies. This family's cancer history prompted a family history investigation of women treated for ovarian germ cell malignancies in the Gynecologic-Oncology Clinic at the University of wisconsin. One of the eight patients whose family histories were reviewed had an uncle who had been diagnosed with testicular germ cell cancer. A review found six other previously reported families in which more than one relative had been diagnosed with a malignant ovarian germ cell tumor. Additionally, several cases of families with both males and females diagnosed with germ cell cancers have been documented. The low incidence of ovarian germ cell cancers suggests that multiple occurrences in the same family may not be due to chance. Rather, it is possible that a gene conferring susceptibility to ovarian germ cell cancers, and possibly to germ cell tumors in males as well, is present in at least some of these families.

8/645. Severe rhabdomyolysis as a complication of high-dose chemotherapy in a patient with advanced testicular cancer.

    BACKGROUND: A 38-year-old man was diagnosed with choriocarcinoma in the left testis, a 9 cm retroperitoneal tumor, left hydronephrosis, multiple lung metastasis and gynecomastia. His serum hCG level decreased but was still above the normal range after four courses of standard chemotherapy. methods: High-dose chemotherapy was then given with ice (ifosfamide, carboplatin, etoposide) from days -7 to-3. RESULTS/DISCUSSION: On day -2 the patient became confused and hallucinated, so the sedatives haloperidol and flunitrazepam were administrated. His creatinine phosphokinase levels increased to 6150 IU/L (reference range <197 IU/L) on day 0. myoglobinuria and myoglobinemia were noted and the renal dysfunction progressed. A peripheral blood stem cell transplantation was performed after hemodialysis on day 0. Although his bone marrow recovered, the patient died of respiratory failure on day 18. An autopsy revealed massive pulmonary bleeding. Pretreatment renal dysfunction, renal damage by high-dose chemotherapy, ifosfamide-induced hallucinations and the administration of sedatives, such as haloperidol and flunitrazepam, may have been causative factors for the rhabdomyolysis observed in this patient.

9/645. Case of gonadoblastoma in a 9-year-old boy without physical abnormalities.

    BACKGROUND: A 9-year-old boy was admitted to Jikei University Hospital complaining of gradual enlarging of the left scrotal contents. methods/RESULTS: physical examination was significant for bilateral descended testicles. No abnormalities were detected in the testicles or along the spermatic cords. Scrotal ultrasound showed that hyperechoic shadows were recognized in the central area of the left testicle. Subsequent testicular biopsy and histopathological examination showed intratubular malignant germ cells in the testicular tubules. One week later, left orchiectomy was performed. CONCLUSIONS: Histopathological evaluation revealed gonadoblastoma. gonadoblastoma, a rare gonadal neoplasm, is composed of germ cells and sex cord derivatives and usually occurs in phenotypically female patients with gonadal dysgenesis. To date, only three cases of gonadoblastoma have been reported in anatomically normal male patients with scrotal testicles. We report on a case of gonadoblastoma unaccompanied by a germ cell tumor in a physically normal male.

10/645. Actinomycin D revisited in testicular cancer. A case report.

    BACKGROUND: Between 20-30% of patients with advanced germ cell tumors relapse or fail to achieve a complete response to conventional cisplatin based chemotherapy. Ifosphamide has been used very effectively in combination with cisplatin and etoposide (VIP) or in combination with cisplatin and vinblastine (VeIP). Actinomycin D with chlorambucil and methotrexate was widely used in the 1960s with complete responses in 20% of patients and long term survival of 6-10%. There exists no information on the use of actinomycin as a salvage in cisplatin refractory patients. methods AND RESULTS: One patient with metastatic germ cell tumor who failed chemotherapy with cisplatin and ifosphamide was successfully treated with an actinomycin D based regimen. CONCLUSIONS: Actinomycin D is an active agent in testicular cancer and maybe used in patients refractory to platinum.
