1/101. 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.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/101. 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.- - - - - - - - - - ranking = 0.93945654109194keywords = cancer (Clic here for more details about this article) |

4/101. 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.- - - - - - - - - - ranking = 0.23486413527299keywords = cancer (Clic here for more details about this article) |
5/101. 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.- - - - - - - - - - ranking = 1.1743206763649keywords = cancer (Clic here for more details about this article) |
6/101. 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.- - - - - - - - - - ranking = 0.23486413527299keywords = cancer (Clic here for more details about this article) |
7/101. Case report: clostridium septicum infection presenting as liver abscess in a case of choriocarcinoma with liver metastasis.clostridium septicum is an anaerobic, gram-positive bacillus. infection with this organism has a known association with malignant diseases, especially colon and haematological cancers. clostridium septicum is rarely found to be a pathogen of liver abscess. Herein, we report the case of a female choriocarcinoma patient with liver metastasis in which C. septicum infection presented as a gas-forming liver abscess. This case and previous reports indicate that once C. septicum is identified as a pathogen in liver abscess, metastatic liver tumours should be highly suspected.- - - - - - - - - - ranking = 0.23486413527299keywords = cancer (Clic here for more details about this article) |
8/101. choriocarcinoma arising in a squamous cell carcinoma of the esophagus.Extragonadal germ cell tumors are rare neoplasms with histologic features comparable to those of gonadal origin. Squamous cell carcinoma of the esophagus was diagnosed in a 53-year-old male patient, and was palliated for a short period by cisplatin plus 5-fluorouracil. Clinical deterioration and development of gynecomastia led to diagnosis of hormone-secreting choriocarcinoma that originated within the squamous cell tumor of the esophagus. Salvage chemotherapy affected the markers but not the tumor. Extragonadal choriocarcinoma is a chemosensitive tumor, but when arising within squamous cell carcinoma of the esophagus it may be chemoresistant, and lead to a fatal outcome.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
9/101. Chorioepithelioma presenting as a bleeding gingival mass.A case is reported in which a very malignant neoplasm appeared clinically to be a pregnancy tumor or a hemangioma. There was, of course, no question as to the cause of death in this particular case. It was of interest because of the rarity of the tumor, the metastasis to the oral cavity, and the fact that the final diagnosis was established from pathologic examination. The case demonstrates, with emphasis, the great importance of biopsy and routine pathologic examination of all tissue for accurate and correct diagnosis, regardless of its clinical appearance.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
10/101. Acute tumor lysis syndrome with choriocarcinoma.A 52-year-old man with retroperitoneal nodal, lung, and liver metastases from choriocarcinoma received chemotherapy with etoposide, cisplatin, and bleomycin. Within 48 hours of starting treatment, he had hypotension, hypoxemia, and anuria. Laboratory values showed hyperuricemia, hyperkalemia, hyperphosphatemia, hypocalcemia, and metabolic acidosis. He was placed on mechanical ventilation, and hemodialysis was instituted, with marked improvement in renal function. A second, shortened course of chemotherapy with carboplatin and etoposide was given 21 days later. However, on hospital day 48, the patient died of progressive pulmonary insufficiency and cardiac arrest. This represents the first reported case of acute tumor lysis syndrome after systemic chemotherapy for advanced nonseminomatous germ cell cancer.- - - - - - - - - - ranking = 0.23486413527299keywords = cancer (Clic here for more details about this article) |
