1/602. 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.

2/602. 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.

3/602. Latent vaginal choriocarcinoma in a postmenopausal woman.

    A 50-year-old Japanese female with choriocarcinoma showed three unusual features: the primary tumor developed in the vagina ectopically without uterine lesion; the first symptoms of atypical vaginal bleeding and coughing occurred 23 years after the last pregnancy; and the tumor appeared during postmenopause. The possible mechanisms for the ectopic location and latency are discussed. ( info)

4/602. Mediastinal choriocarcinoma in a chromatin-positive boy.

    A case of primary mediastinal choriocarcinoma in a chromatin-positive boy is reported. The incidence of neoplasms in patients with so-called Klinefelter's syndrome is discussed as well as embryogenesis and diagnostic evaluation in patients presenting with this tumor. ( info)

5/602. Malignant testicular tumors in three brothers.

    Three brothers out of four had malignant testicular tumors. The first of them had choriocarcinoma, the second seminoma, and the third teratocarcinoma of the testis. ( info)

6/602. Metastatic lung choriocarcinoma resected nine years after hydatidiform mole.

    A 38-year-old woman with metastatic choriocarcinoma of the lung had been treated for a hydatidiform mole nine years previously. During the interval she had conceived and given birth to a child. Following lobectomy she has been metastasis-free for five years. ( info)

7/602. pancreaticoduodenectomy for metastatic tumors to the periampullary region.

    Although operative resection of metastatic lesions to the liver, lung, and brain has proved to be useful, only recently have there been a few reports of pancreaticoduodenectomies in selected cases of metastases to the periampullary region. In this report we present four cases of proven metastatic disease to the periampullary region in which the lesions were treated by pancreaticoduodenectomy. Metastatic tumors corresponded to a melanoma of unknown primary site, choriocarcinoma, high-grade liposarcoma of the leg, and a small cell cancer of the lung. All four patients survived the operation and had no major complications. Two patients died of recurrence of their tumors, 6 and 63 months, respectively, after operation; the other two patients are alive 21 and 12 months, respectively, after operation. It can be inferred from this small but documented experience, as well as a review of the literature, that pancreaticoduodenectomy for metastatic disease can be considered in selected patients, as long as this operation is performed by experienced surgeons who have achieved minimal or no morbidity and mortality with it.

8/602. choriocarcinoma co-existent with an intact pregnancy: case report and review of the literature.

    A patient presenting with antepartum haemorrhage due to a vaginal metastasis of choriocarcinoma is reported. Following delivery she was successfully treated with chemotherapy and surgery. This report details this unusual presentation and reviews the literature on this rare condition. ( info)

9/602. breast cancer with choriocarcinomatous features: A case report with cytopathologic details.

    A case of breast cancer with choriocarcinomatous features (BCCF) is reported. The patient was a 38-year-old Japanese female with a long history of schizophrenia. Her nursing staff noticed a palpable mass in her right breast, which showed rapid growth. Following cytopathologic confirmation of a malignant breast tumor, she underwent mastectomy with ipsilateral axillary lymph node dissection. Histologic examination revealed BCCF, which was positive for placental alkaline phosphatase and human chorionic gonadotropin (HCG) by immunohistochemistry. The serum HCG level was high. She died 7 months postoperatively, with multiple metastases of BCCF to the chest wall, lung and liver. ( info)

10/602. Primary choriocarcinoma and human chorionic gonadotrophin-producing giant cell carcinoma of the lung: are they independent entities?

    AIMS: Human chorionic gonadotrophin (hCG) is a useful marker for chorionic proliferative disorders, such as choriocarcinoma. Although hCG synthesis in lung cancers is frequent, primary pulmonary choriocarcinoma (PCC) is rare. To clarify the differences between primary choriocarcinoma and hCG-producing giant cell carcinoma (GCC) of the lung, we compared the clinicopathological and immunohistochemical findings of these tumours. methods AND RESULTS: Three patients, one with PCC and two with hCG-producing GCC, were included in this study. They were all middle-aged men and habitual smokers. The growth of these tumours and the progression of the clinical courses were extremely rapid, and the patients all died within 8 months after the pulmonary tumours were found. Haemorrhagic appearance was a common macroscopic feature of the specimens obtained. Microscopically, both types of tumours mainly consisted of atypical polygonal cells. While PCC contained many syncytial trophoblast-like multinucleated cells that had strong immunoreactivity for anti-hCG, such cells were relatively few in hCG-producing GCC. These histological and immunohistochemical findings reflected the serum test result for hCG, which was higher in the case of PCC. CONCLUSIONS: There are a few differences between PCC and hCG-producing GCC, as described above. Reliable distinction between them seems to be difficult for pathologists and worthless for clinicians.
