1/1757. trisomy 9 in a patient with secondary acute myelogenous leukemia detected by fluorescent in situ hybridization.Fluorescent in situ hybridization (FISH) is a molecular cytogenetic technique that is playing an increasingly important role for augmenting the findings of conventional cytogenetics. Here we present the case history of a patient with the clinical diagnosis of secondary acute myelogenous leukemia whose bone marrow cells were found to be hyperdiploid with an extra C group chromosome in a less than optimal preparation. By using FISH the extra chromosome was unequivocally determined to be a chromosome 9. The detection of trisomy 9 in this patient underscores the utility of FISH as an adjunct to GTG banding in the routine diagnosis and management of leukemic patients.- - - - - - - - - - ranking = 1keywords = leukemia, m (Clic here for more details about this article) |
2/1757. Ki-1 large-cell anaplastic lymphoma after Ewing sarcoma.PURPOSE: A large cell anaplastic lymphoma that developed after treatment of a Ewing sarcoma (ES) is described. PATIENT: An 11-year-old girl with a pelvic ES developed a large cell, Ki-1 , anaplastic lymphoma in the same anatomic location 10 months after multimodal therapy. RESULTS: ES recurred in the primary site 16 months after allogeneic marrow transplantation and 3.5 years after initial diagnosis, but the patient remains in remission from her lymphoma. CONCLUSION: The occurrence of lymphoma and ES in a short time interval in the same patient is very unusual. Whether etiologic factors other than chemoradiotherapy, including genetic disposition, play a role remains to be elucidated.- - - - - - - - - - ranking = 8.0055000612062E-5keywords = m (Clic here for more details about this article) |
3/1757. The effectiveness of chemotherapy with cisplatin and 5-fluorouracil for recurrent small cell neuroendocrine carcinoma of the rectum: report of a case.We report herein the case of a 46-year-old-man with small cell neuroendocrine carcinoma (NEC) concomitant with large villous adenoma of the rectum, who underwent abdominoperineal resection with regional lymphnode dissection. The resected specimen was histologically found to contain a small lesion of NEC confined to the submucosa in the large adenoma. A computed tomography scan done 4 months postoperatively revealed recurrences in the liver, lymph nodes, and bone. Therefore, two cycles of sequential intravenous combined chemotherapy with standard doses of cisplatin and 5-fluorouracil (5-FU) were administered, after which the size of each tumor decreased remarkably. Nevertheless, the patient died 8 months after the operation. As there was a fair response of this tumor to the combined chemotherapy of cisplatin and 5-FU, this regimen against NEC of the colon and rectum should be given consideration.- - - - - - - - - - ranking = 9.3036892603207E-5keywords = m (Clic here for more details about this article) |
4/1757. Tumor-related osteomalacia followed after treatment by hyperparathyroidism.Tumor-induced osteomalacia is due to renal phosphate wasting in response to a humoral factor produced by a tumor, usually a benign mesenchymal tumor. Removal of the tumor is followed by resolution of the metabolic disorder. physicians should be aware that sporadic renal phosphate wasting in an adult should prompt a search for a tumor. A case of tumor-induced osteomalacia due to a nonossifying fibroma of the radius is reported. After removal of the tumor, renal phosphate excretion returned to normal, but the patient developed tertiary hyperparathyroidism. Eight years elapsed between symptom onset and the diagnosis of the tumor. The pathogenesis of tumor-induced osteomalacia and the role of treatment for renal phosphate wasting on the subsequent development of hyperthyroidism are discussed.- - - - - - - - - - ranking = 9.3036892603207E-5keywords = m (Clic here for more details about this article) |
5/1757. Ovarian carcinoma, endometrial carcinoma, and pregnancy.A 31-year-old G1 P0 patient with a history of infertility presented with light spotting and cramping at the end of her first trimester. An ultrasonogram at 19 weeks gestation revealed an intrauterine gestation of 21 weeks, a large leiomyoma, and a 8.9 x 6.8 cm complex left ovarian mass. At 35 weeks gestation she had an emergency cesarean section and left salpingo-oophorectomy due to a presumed ruptured ovarian mass. The ovarian mass was diagnosed as a serous cystadenocarcinoma. An exploratory laparotomy with a total abdominal hysterectomy, a right salpingo-oophorectomy, omental biopsy, and periaortic node sampling at 9 weeks postpartum revealed a diagnosis of stage IC ovarian serous cystadenocarcinoma and a stage IA secretory endometrial adenocarcinoma. Adjunctive 32P therapy was successfully administered and at this time the patient has had no recurrence.- - - - - - - - - - ranking = 8.2218649277253E-5keywords = m (Clic here for more details about this article) |
6/1757. Secondary glioblastoma remarkably reduced by steroid administration after anaplastic transformation from gliomatosis cerebri--case report.A 45-year-old female presented with gliomatosis cerebri manifesting as hemiballismus-like involuntary movement in the arm, motor weakness in the leg, and hypesthesia in her left side. Computed tomography showed only diffuse swelling of the right cerebral hemisphere, but T2-weighted magnetic resonance imaging revealed a diffuse lesion spreading from the right thalamus to the temporal, parietal, and occipital lobes on the same side. No abnormal enhancement was recognized. cerebral angiography showed no specific finding. A right occipital lobectomy was performed to confirm the diagnosis of gliomatosis cerebri. Anaplastic transformation was recognized 5 months later. The disease did not resolve with radiation or interferon administration, but steroid therapy achieved remarkably effective tumor regression. The patient died due to pneumonia. autopsy showed the features of diffuse glioblastoma. Steroid therapy may be an effective treatment for gliomatosis cerebri before the terminal stage.- - - - - - - - - - ranking = 0.00012765527124626keywords = m (Clic here for more details about this article) |
7/1757. Angiosarcoma. A rare secondary malignancy after breast cancer treatment.life-saving mastectomy and radiation therapy are established in the treatment of early stage breast cancer. Angiosarcoma, i.e. malignant angioendothelioma, is a rare tumor which can develop after several years of such treatment. The number of post-operative and post-irradiation angiosarcomas has increased in recent years. We report four cases of angiosarcoma which occurred after treatment of breast cancer and review the literature. In two of these cases the angiosarcoma developed on the irradiated breast skin after partial mastectomy and radiation therapy, in the other two cases the angiosarcoma appeared on a chronically edematous arm after radical mastectomy and radiation therapy.- - - - - - - - - - ranking = 6.9236757286107E-5keywords = m (Clic here for more details about this article) |
8/1757. Hodgkin's disease following extranodal marginal zone B-cell lymphoma in remission.A patient who developed Hodgkin's disease after an 11-year remission of marginal zone B-cell (MZB) lymphoma (low grade B-cell lymphoma of mucosa-associated lymphoid tissue type) is presented. Except for L26/CD20 expression by reed-sternberg cells, morphologic, immunophenotypic, and genotypic findings were compatible with the diagnosis of Hodgkin's disease. The relationship between Hodgkin's disease and the preceding MZB lymphoma in this patient is discussed.- - - - - - - - - - ranking = 6.4909459955726E-5keywords = m (Clic here for more details about this article) |
9/1757. Multiple cutaneous granular cell tumors of the scrotum.A 55-year-old black man with two firm intradermal nodules of the scrotum is presented. On histopathologic examination, the nodules were determined to be cutaneous granular cell tumors. This was confirmed by strong immunohistochemical reactivity to S-100 protein. There are no previous reports of multiple granular cell tumors of the male genitalia. Only one report of a solitary granular cell tumor of the scrotum appears in the literature.- - - - - - - - - - ranking = 5.1927567964581E-5keywords = m (Clic here for more details about this article) |
10/1757. Synovial sarcoma in the parapharyngeal space: case report and review of the literature.We encountered a rare case of synovial sarcoma in the parapharynx of a 47-year-old Japanese man. This patient presented with an enlarging tumor in the right side of his neck that had grown progressively over a 4-week period. Radiological examinations revealed that the tumor arose from the parapharyngeal space. The tumor could not be completely removed at surgery. Metastasis to the lumbar vertebra was detected postoperatively. The patient underwent three courses of chemotherapy and the delivery of palliative radiation to the lumbar vertebra without success. The patient died of lung metastasis 7 months after surgery.- - - - - - - - - - ranking = 3.8945675973435E-5keywords = m (Clic here for more details about this article) |
